API Settings

API Settings provide the opportunity to configure the Messenger API. Primarily these settings control how we call your servers when new messages or statuses arrive into our system.

Callback URL Format

Callbacks from the Messenger API can be either in XML or the HTTP FORM format. Changing this setting modifies the return payload for all callbacks sent to the Callback URL, so make sure your server supports the selected format.

Default Callback URL for Replies

You can specify the Callback URL for replies within each individual API call and this works well for messages that come in as replies to outbound messages, however it does not function when you have your own virtual number or short code. Setting this value to an http or https endpoint is supported, and you can also specify an email address using the mailto format.

Default Callback URL for Statuses

You can specify the Callback URL for Status messages within each individual API call and this works well for messages that come in as replies to outbound messages, however it does not function when you have your own virtual number or shortcode. Setting this value to an http or https endpoint is supported, but mailto: is not supported for status callbacks.
