# Send an einvoice for credit notes

> For the complete machine-readable documentation index, see [llms.txt](https://apidocs.chargebee.com/llms.txt).


[Idempotency Supported](/docs/api/idempotency)

This endpoint is used to send an e-invoice for invoice. To support cases like TDS and invoice edits, we need to stop auto e-invoice sending and be able to send e-invoices manually. This endpoint schedules e-invoices manually. This operation is not allowed when any of the following condition matches:

-   If e-invoicing is not enabled at the site and customer level.
    
-   If there is an e-invoice generated already for the invoice.
    
-   If the **Use automatic e-invoicing** option is selected.
    
-   If there are no generated e-invoices with the `failed` or `skipped` status.
    
-   If the invoice status is `voided` or `pending`.
