📘
Getting the final status for a message
Once submitted, we process your message and try to deliver it down one of the channels specified. It is still possible the message can fail at this stage if no channels accept the message. To find the final status of a message you can query it using the Get Status method, or register a Webhook to have data pushed to your systems.

Batch Submission Response Details

Successful Submission Response

Once you successfully send to the Omnichannel API, you then receive a HTTP 202 and a JSON body. The JSON is an array of objects in the following format, one for each message submitted in the batch:

Property	Type	Description
index	int	The index of the message send request in the original batch submission this response is for.
messageId	string	The unique identifier for the message. This id can be used to request status details and correlate inbounds and receipts to the original message.

🚧
Whats happens after sending a batch of messages
The messages are processed as fast as possible after submission, but it may take a few seconds before this process is finished, and the message is available for status updates. You can get updates on your messages statuses asynchronously using our webhooks system.
