The Manage Registration Overview diagram displays the main steps for the Supplier registration process.
Note: With the April 2023 release, an approved linking request is required when the Supplier payment preference flag is set to `NO`. The flag default state is set to `NO`. If the display options for Supplier payment preferences are set to `YES`, then the available Supplier payment preferences are displayed. Contact your Mastercard representative to set the Supplier payment preferences flag.

**Step 1:** The Supplier Payment Agent submits the registration request by calling the Supplier registration APIs.

**Step 2:** Commercial Direct Payments validates the registration.

**Step 3:** Commercial Direct Payments completes the request.

**Step 4:** Commercial Direct Payments notifies the Supplier Payment Agent of the completed registration request.
