##### Following are the execution steps: {#following-are-the-execution-steps}

1. The consumer signs into the issuer's app.
2. The customer authenticates the consumer.
3. The customer sends an encrypted request to the Points Activity Service for points adjustment.
   * The request for points adjustment requires the following mandatory input parameters:
     * bankAccountNumber
     * pointsToAdjust
     * adjustmentTypeCode
     * adjustmentReason
     * adjustedBy
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 encrypted request received via the `/points-adjustments` endpoint.
6. The Points Activity Service performs points adjustment.
7. The Points Activity Service sends a response with the number of points adjusted (200).
8. The Points Activity Service sends a response with a status code of 4xx/5xx in case of an invalid request.

You will receive an error response for an invalid request or any missing request parameter. In that case, you need to update the input and perform step 3 again.
