Chargebee provides HTTP based API which follows the essence of REST*. The HTTP protocol's rules are followed thereby enabling simple HTTP client tools like "curl" to be used.

Here are the recent changes in Chargebee's API V2 . Subscribe to keep track of the changes and upgrades in Chargebee API.

The following client libraries provide a "easy to use" wrapper around the raw HTTP based API.

Refer to our documentation for a detailed definition & description of all the components in Chargebee.

Chargebee now supports two API versions - V1 and V2. V2 version has been released to accommodate certain backwards-incompatible changes that we wanted to make over V1 for a more streamlined functionality.

All further developments will happen in V2. However we will continue to support V1 in order to avoid breaking your code.

Downloading/Installing Client libraries:

As we support multiple API versions now, we request you to

  • Use the appropriate GitHub branches if you are building from source. The master branch will have the API V2 code, and chargebee-v1 branch will have the API V1 code.
  • Use appropriate version specifiers, if you are installing/updating using package managers (composer, gem, pip, easy_install, maven, NuGet, npm, etc.).

Webhooks and API Versions:

With multiple versions of API being supported, the property Api Version has been added to Webhooks, which decides the structure of the event content sent to the webhooks.

Which API version am I using?

Find out the version of the API you are using, with the following indicators:

  • The Chargebee client lib release version: Release versions 1.x.x indicate that you're on V1 and 2.x.x indicate that you are on V2.
  • The API end-points: They start with /api/v1 for V1 and /api/v2 for V2.

What changes does Chargebee consider to be "backwards-compatible"?

  • Adding new API resources.
  • Adding new attributes to existing API responses.
  • Changing the order of attributes in existing API responses.
  • Adding new API methods for a resource.
  • Adding new 'optional' input params to existing API methods.
  • Adding new attributes to existing API responses.
  • Making an input param 'required' in API methods (very rare).
  • Adding new event types.

You could use cURL to test Chargebee API easily from command line.

curl https://{site} -u {site_api_key}:

Chargebee uses HTTP BASIC Auth for authenticating the API calls. The user name is your "API key" and the password is empty. The API key could be got from 'Your API Keys' page under integration tab in the web client console.

Note: The API keys are different for your test site and your live site.

Authentication in cURL

For curl you could specify the API key using the -u option

curl {api url} -u {api key}:

Since the password is not present, nothing is specified after the colon(:)

Chargebee follows the REST model of exposing resources as urls. For example, subscriptions are exposed as



The HTTP method (like GET,POST) determines the operation type on the resource. Query parameters allow you to provide additional options to the GET requests. POST parameters provide the data to write operations like creation, modification of resource(s).

By default curl uses GET method. Use -X option to specify a specific HTTP method to use. For passing parameters, use -d option. ( Note: cURL automatically uses to POST method if any parameter is sent via -d option ).


The response is in JSON format. Currently Chargebee does not support any other response format.

Some of the resources have a corresponding details page in the Chargebee's admin console. In some cases you might want to construct the admin console url for easy access from your app (or from exported xls sheets). As the admin console urls are based on internal ids you need to construct the url in the below given format.


Here is an example of a constructed url for a subscription with id 123xyz


  • Accessing the constructed url in a browser will redirect it to the details page.
  • The login page will be shown if the user has not yet logged-in into Chargebee's admin console.
  • Not all resources will have the corresponding details page. To know if it is supported, please look at the cURL documentation under the retrieve operation for that resource.
  • Do not store the redirected internal id based url as it may change.

Chargebee supports billing in 100+ currencies.

Take a look at the list of supported currencies here.

Handling Currency Units

While specifying amount in any currency, you need to provide the amount in the smallest unit of that currency. For example, to specify an amount of $1.50, you would set amount=150 (i.e. 150 cents).

For zero decimal currencies (currencies that do not have decimal units), however, you need to provide the amount in the regular denomination. For example, to specify an amount of ¥15, you would set amount=15 (i.e. 15 yens).

Chargebee currently supports below zero-decimal currencies:

  • KRW - South Korean Won
  • JPY - Japanese Yen
  • XAF - Central African CFA Franc
  • XOF - West African CFA Franc

Multicurrency Support

With our Multicurrency support, you will be able to process transactions in additional currencies apart from your site's Base currency.

Before enabling Multicurrency support, ensure that the currency_code input parameter is passed to the following methods, to avoid the cannot be blank error:

Note: If you are using the older version of our API (V1), you need to upgrade to our latest version (V2) to be able to pass currency_code input parameter to the above methods. Otherwise, with Multicurrency support enabled, the above methods will throw cannot be blank error in (V1).

Chargebee supports configuring multiple gateway accounts for a gateway type (eg: you can configure multiple accounts to process multiple currencies).

The following methods were accepting gateway / card[gateway] / payment_method[gateway] input parameters. This is an optional parameter, which needs to be passed only if you want to override your gateway account preferences configured under Smart Routing:

If you were passing the gateway parameter, ensure that you pass the gateway_account_id parameter instead to avoid getting the multiple_gateway_accounts_exist error.

Note: If you are using the older version of our API (V1), you need to upgrade to our latest version (V2) to be able to pass gateway_account_id input parameter for the above methods. Otherwise, with multiple accounts of a gateway type configured, the above methods will throw the multiple_gateway_accounts_exist error in (V1).

Chargebee supports multiple payment methods/sources for a customer. So a customer can have a Card and a Paypal Account linked to them, or they can have multiple cards. Moreover, you can mark one of them as Primary and one as Backup payment source.

The purpose of a Backup payment source is that if a charge made via the Primary payment source fails, then the backup payment source will be automatically used for processing the transaction.

Updating a payment source:

  1. To update the Primary payment source for a customer:
    • Use any of the create payment source APIs with 'replace_primary_payment_source' set to 'true'. This will update the payment source and make it the Primary payment source for the customer.
  2. To update alternate payment sources:
    • Delete the payment source that you want to update
    • Create a payment source for the customer using any of the create payment source APIs

An optional parameter, payment_source_id, is available in the following APIs:


  1. If you are using the older version of our API (V1), you need to upgrade to our latest version (V2) to be able to use Payment Source API.
  2. The first payment source created for a customer will be automatically marked as the Primary payment source for the customer.
  3. The Payment Source provided in the hosted pages by a customer always replaces the Primary payment source for the customer. If a payment source does not exist, it creates a new payment source and marks it as Primary.

HTTP status code is used to indicate success or failure of an API call. The body of the response contains the details of the error in JSON format.

Sample error response:

Below is the sample error that is returned for 'create subscription' api call when the plan referred in the plan_id parameter is not present. The returned http status code will be 404.

{ "message":"Plan is not present", "type":"invalid_request" "api_error_code":"resource_not_found", "param":"plan_id" }

Http Status Codes

The standard http status codes used are

  • 2XX The response code in this range implies the API call has succeeded.
  • 3XX This range is not used currently.
  • 4XX response codes indicate failure due to wrong input (i.e, client) side. As the usable list of http codes in the 4xx range is limited we predominantly use the 400 ( BAD REQUEST ) error code for client side errors.
  • 5XX response codes indicate API request was valid but failed due to bugs on the Chargebee server side.

Error Attributes

The following attributes are returned as part of the error content.
A descriptive information about the error. This is for developer(/merchant) consumption and should not be used for showing errors to your customers.
An optional attribute which groups errors based on the error handling routine that is required. The types are payment, invalid_request and operation_failed. The client libraries throw a corresponding exception for easy error handling.
A more specific code allowing you to handle the specific errors.
An optional attribute which is filled if the error was due to a specific parameter. The parameter name format that is sent is based on the underlying Chargebee's REST api format which can be referred in cURL api documentation.
For example, in create subscription for a customer API call if the plan referred in the plan_id parameter is not present in the site, then param value set as plan_id. For 'multivalued' parameters , the index is part of the parameter name. For the same API, if the second addon id is wrongly passed then the param value is set as addons[id][2].
Note: For the same API customer id is part of the url. If the given customer is not present, then resource_not_found error is thrown without the param attribute.

Note: There would be additional deprecated attributes (like error_code) which are present to support older versions of the libraries.

Error handling recommendations

Chargebee will return the first encountered error when validating the API call. Hence we strongly recommend you to validate the user input on your side before calling Chargebee's API. Otherwise you will have to show the mistakes one at a time for the user to correct it before proceeding to the next.

There are cases where you have to depend on Chargebee's validation for handling errors like coupon code validation or VAT validations. In such cases check for the specific param and api_error_code combination to show proper error message to your users.

The following are the list of codes grouped based on type.

Note: 'New' codes might get added (though additions are very rare). If you are handling for specific codes also ensure that there is a default block for handling unknown(/new) error codes.

These errors may occur when trying to store the payment method details(such as card, paypal, ACH etc) or when trying to collect a payment. These errors should be handled and appropriate message should be shown to the user. The type attribute in the error response is sent as payment.

Returned when the payment collection fails.
HTTP Code: 400, Sample message: Subscription cannot be created as the payment collection failed. Gateway Error: Card declined.
Returned when validation or verification fails for the provided payment method. For example if the payment method is card, this will include all card parameter validation errors and also verification failures from the gateway.
HTTP Code: 400, Sample message: Problem while adding the card. Error message : AVS check failed.
Returned when the request requires payment collection but the 'payment method' details (such as card) is not present for the customer. This error will not occur if auto-collection is disabled for the customer.
HTTP Code: 400, Sample message: Card is not present when reactivating the subscription
Returned when the payment gateway configured is incompatible with the transactional currency. This error will not occur if auto-collection is disabled for the customer.
HTTP Code: 400, Sample message: The configured gateway account [ PAYPAL_EXPRESS_CHECKOUT ] does not support transactions in INR.

The following errors are caused due to invalid request. In most cases the errors should occur only during the development phase. The type attribute in the error response is sent as invalid_request.

Returned when any of resource(s) referred in the request is not found.
HTTP Code: 404, Sample message: 82sa2Sqa5 not found
Returned when any limit constraint is violated by the request. For example this error is thrown when the coupon provided has already expired or its maximum redemption count has been reached.
HTTP Code: 400, Sample message: Coupon has expired
Returned when the value does not meet the required specification for the parameter. For example, wrong email format. It is strongly recommended to do the validation at your end before calling Chargebee's API (other than specific cases like VAT number validation).
HTTP Code: 400, Sample message: invalid email format
Returned when the request provides a duplicate value for an attribute that is specified as unique for that site. For example in 'create subscription api' if you are passing the subscription id then this error will be thrown if a subscription exists in site with the same id.
HTTP Code: 400, Sample message: The value Hy5r4129u is already present.
Returned when the requested operation is not allowed for current state of the resource. This error will occur if the state of the resource has not been checked for the validity of the request. For example this error is returned when we try to schedule subscription changes at 'end of term' for canceled subscriptions.
HTTP Code: 409, Sample message: Only pending invoices can be closed.
Returned when the 'http method', specified in the request, is not allowed for this URL. It should not occur if you are using one of the standard client library.
HTTP Code: 405, Sample message: Sorry,the http method GET is not supported for this URL.
Returned when the request has incompatible values or does not match the API specification. As it is a generic error, handling this error is recommended only in combination with param attribute.
HTTP Code: 400, Sample message: The plan's billing period and addon's billing period are incompatible.

HTTP Code: 400, Sample message:

These errors are returned when the request was valid but the requested operation could not be completed. These errors should occur very rarely. You generally need not handle them specifically other than showing a generic error message to your users. The type attribute in the error response is sent as operation_failed.

Returned when the request parameters were right but the operation couldn't be completed due to a bug in Chargebee side.
HTTP Code: 500, Sample message: Sorry,Something went wrong when trying to process the request.
Returned when temporary occured in Chargebee side. The request can be re-tried, with exponential backoff in case of repeat failures.
HTTP Code: 503, Sample message: Sorry,A temporary error occured when trying to process the request.
Returned when request is blocked for your site. The blocking could be only for a specific set of operation(s) . The reason would be provided as part of the message. You would have to contact support for additional details.
HTTP Code: 403, Sample message: Sorry, The request is blocked
Returned when requests have been blocked temporarily due to request count exceeding acceptable limits.
HTTP Code: 429, Sample message: Sorry, access has been blocked temporarily due to request count exceeding acceptable limits. Please try after some time.

Currently the api_request_limit_exceeded occurs when the number of API calls exceeds the threshold value.

Threshold value for test site: ~750 API calls in 5 minutes.

Threshold value for live site: ~150 API calls per site per minute.

If you would want the limit to be increased for a short period of time for scenarios such as importing subscriptions, promotional campaigns, etc., reach out to

Most of these errors occur due to improper API environment setup in your server or changes to the site's configuration. The type attribute is not sent in the error response.

Returned when authentication failed for the request. The possible reasons could be the api key is invalid or authentication header is not present in the request or the header's format is invalid.
HTTP Code: 401, Sample message: Sorry, authentication failed. Invalid API Key.
Returned when the API key does not have sufficient privileges to perform the particular operation.
HTTP Code: 403, Sample message: Sorry, authorization failed. The key does not have the required permissions
Returned when the site is not found.
HTTP Code: 404, Sample message: Sorry, we couldn't find the site acme
Returned when the request is not compatible with the configuration for the site or the configuration is incomplete.
HTTP Code: 400, Sample message: Return URL for the hosted page not configured.

Sometimes you would want to disable emails or webhooks for the events that are generated for a particular api call. Typically you would need this when you are migrating customers from your system to Chargebee via api. One option would be to disable all the emails(/webhooks) for all events during the import process. But then you would still want to send emails for new customers who are signing up.
Chargebee supports custom http headers on each api request that allow you to control the actions that are triggered on the events generated by that particular api call.

  • To skip all actions to be done on the events pass the header chargebee-event-actions with value all-disabled
  • To skip only emails pass the header chargebee-event-email with value all-disabled
  • Similarly to skip only webhooks pass chargebee-event-webhook with value all-disabled
        curl \
     -H chargebee-event-actions:all-disabled \
     -u myapikey: \
     -d customer[email]="" \

Note: Reminder mails (such as card expiry) and other scheduled events cannot be disabled using this option

Passing user details like IP address, email address and Device information from your website to Chargebee is always useful. IP address information is routed to the payment gateway (where it will be validated against active fraud detection filters), used for EU tax validation, referral integration and event reports. Email addresses and Device information, even more ubiquitous, are used for identification. Chargebee supports http headers to send user details.

Use the following headers to send user details across:

  • For the IP address of the customer where the request originated - chargebee-request-origin-ip; where an example is
  • For details of the customer - chargebee-request-origin-user; where an example is
  • For the device from which the customer has made the request - chargebee-request-origin-device; where an example is Android.
 curl \
     -H chargebee-request-origin-ip:\
     -H chargebee-request-origin-device:Android\
     -u myapikey: \
     -d customer[email]="" \

Chargebee provides the option of creating custom fields for the Customer and Subscription objects. You can use this option to track additional information about a customer or their subscription. Once the custom fields are created, they can be added to the hosted checkout pages and invoices. They can be accessed through the web interface, and via the API. More on Custom Fields here.

Custom Fields for Customers

Use the option to create custom fields for the Customer object if you need to collect customer-specific information, such as date of birth, age, or gender.

Custom Fields for Subscriptions

Use the option to create custom fields for the Subscription object when the information you need is subscription-specific, and your customers have multiple subscriptions. E.g. Domain URLs, phone numbers, Tracking ID, Shipping Date, t-shirt size, etc.

Meta Data

If you would want to store additional/custom data at a resource's level, you can make use of Meta Data.

For example, if you're a data service provider and would want to store certain features of a particular plan such as "Usage Limit", "Speed within limit", etc., you can have it stored in the Meta data of the Plan.

Meta Data can be passed during the Add/Update operations, for the following resources:

  • Subscriptions
  • Customers
  • Plans
  • Addons
  • Coupons

Meta Data can only be stored in the JSON format. You can also use nested JSON objects.

Considering the same example as above, if you'd want to store the additional features of a particular data plan here's how the JSON would look:

{ "features":{ "usage-limit":"5GB", "speed-within-quota":"2MBbps", "post-usage-quota":"512kbps" } }

  • Meta Data is completely for your reference and will not be visible to customers in the hosted pages. If you'd like to include fields other than the default ones in the hosted pages, you could use Custom Fields.
  • Meta data will not be a filter criteria, or a part of the exports. For this purpose, Custom Fields can be used if necessary.
