Once you've identified a collection from the Catalog (see: Searching the Catalog) you'd like to monitor, you'll want to create a follower collection. This endpoint helps you do that, taking the name of a collection, and providing you with a new collection name which you can use to pull results out of the API

curl -H "INTRIGUE-ACCESS-KEY: xxxyyyzzz" \
     -H "INTRIGUE_SECRET_KEY: xxxyyyzzz" \

  "success": true,
  "message": "success",
  "result": {
    "collection_name" : "microsoft_kl_X"

Now that you have your own follower, you can utilize the standard "Collection Results" api to schedule and pull information out!
