Subscription Feeds

Each subscription object has a set of activity feeds -

https://api.intercom.io/subscriptions/{id}/sent : A feed of notifications sent.
https://api.intercom.io/subscriptions/{id}/error : A feed of errors returned by the webhook.

Where {id} is the value of the subscriptions's id field.

The feeds are not permanent archives and notifications may only retrievable for a period of time; a best effort is made to keep 30 days of activity data.

The error feed for a subscription,https://api.intercom.io/subscriptions/{id}/error, contains a list delivery failures. Each item in the list is the notification that also contains a http_request object that captures the request details.

The http_request object has the following fields -

Attribute	Type	Description
type	string	value is 'http.request'
request_method	string	The HTTP method.
request_uri	string	The fully qualified request URI
request_headers	object	An object containing the request header names and values sent to the server
response_status_code	number	The HTTP response code returned by the server
response_headers	object	An object containing the response header names and values returned by the server
response_entity	string	The response body returned by the server. If the response was JSON, the data will be escaped.
request_entity	string	The request body sent to the server.

The request_entity will contain an escaped JSON document with a field called "type" whose value is "self" indicating the containing notification JSON was what was submitted to the server.

A notification may appear multiple times in the error feed, once for each failed attempt to send.
