Delivery Report (DR) are webhooks for Chat Apps delivery statuses: POST requests sent by the Wavecell platform in JSON format to the callback URL configured for your account.

To receive Wavecell Delivery Reports, you need:

1. A configured account, to use Wavecell Chat Apps product.
2. A webhook: indicate to us which URL Wavecell platform should forward the inbound messages addressed to you.

Flow:

1. You send a message to one user on WhatsApp (for example)
2. The message is delivered or read.
3. Wavecell programmatically transmits the message status to the callback URL configured for your webhook.

Whenever a message will have a new delivery status associated with the stage it is in, Wavecell will send a POST request with the new status.

Retry Mechanism

In case of connection error/timeout or HTTP response code 4XX or 5XX, there will be multiple retry attempts with progressive intervals: 1, 10, 30, 90 sec.
