Be considerate when making API calls, this service is provided free of charge, please do not abuse it. Repeatedly accessing the same feed in very short time periods will result in your IP being blocked or your feed disabled.
If you start receiving a 403 error when you attempt to access your feed it is because you are polling much too quickly and you will need to email firstname.lastname@example.org in order to get your feed reinstated. Please allow as least 2.5 minutes between calls of the same feed and if you are pulling multiple feeds have your application sleep at least 2 seconds between feed requests.
The default content type returned by the API is JSON. Some browsers apparently display it as XML even though the API returns it as JSON. If you want to ensure your content type, append the appropriate switch (.xml or .json).
-- The API will only return data from the point where the feed was created, up to a maximum of 7 days. --
The XML document will contain 0 or more messages. Only the messengers and message types enabled by the customer will be available in this data stream. In addition, viewing limits are imposed on all shared page links and abuse of this feature may cause the viewing limits to come into effect.
