1. The consumer signs into the issuer's app.
2. The customer authenticates the consumer.
3. The customer sends a signed request to the Points Activity Service for points adjustment details.
   * The request for points adjustment details requires the following mandatory request parameters:
     * user_id
     * user_id_type
4. Mastercard API Gateway authenticates/authorizes the customer and routes the request to the Points Activity Service in the case of a valid customer.
5. The Points Activity Service validates the request parameters received via the `/points-adjustments-details` endpoint.
6. The Points Activity Service retrieves the points adjustment details.
7. The Points Activity Service sends a response with points adjustment details (200).
