Headers
Client reference ID for a tax invoice request. This header is optional. Enter a non-blank value between 1 and 255 characters. After this value is used with a tax invoice issuance API, the same API key cannot reuse it, regardless of the request content or endpoint. A duplicate returns 400 Bad Request with INVALID_REQUEST. If you do not receive a response, do not resend the request. Check the accepted request with the request status API.
