This is normally fine when the integration is polling every 10 min, but for the first use of the integration, it might have more postcards farther back in the feed that need to be discovered.
We can store a flag (boolean or oldest feed item date) once we've traversed the feed back to the beginning, and do that on the first poll after installing, if it hasn't been done yet. Or go back one additional page for each polling internal until reaching the oldest page, if we're concerned about hammering the API.
