A successful HTTP response to this endpoint (code 200) does not necessarily mean that the message has been correctly delivered to the consumer, only that it has been created on Partoo. To ensure that the message has been delivered successfully, we recommend subscribing to the Message Updated Webhook, and checking that the status field of the message has switched to Success.

If the answer has failed to be sent, you can send it again by using the /retry endpoint
