What you can build

With this server connected, an agent can send a fraud signal to Sift's Events API (POST /v205/events), fetch the latest Sift score(s) for a user (GET /v205/users/{user_id}/score), remove any existing label on a user (DELETE /v205/users/{user_id}/labels), and fetch the decisions currently applied to a user (GET /v3/accounts/{account_id}/users/{user_id}/decisions).
