You can test multiple account owners using just our API endpoints or using our Connect Widget and API endpoints. By the end of this testing, an object will return for multiple account owners along with their contact information.

You must use the MXCU (OAuth) institution ("institution_code": "mxcu_oauth") in the integrations environment. The MXCU (Credential) institution doesn’t support multiple account owners. If you’re unable to find this institution using our Connect Widget or through searching with our API endpoints, please contact us and we’ll enable this institution for you.
LOGIN CREDENTIALSWhen following the guides to test multiple account owners using the MXCU (OAuth) institution ("institution_code": "mxcu_oauth"), you must use the following credentials:
  • Username: multipleaccountowners
  • Password: testpassword
If you’re only using the API, refer to Integrate without using MX’s Connect Widget guide. For this test institution, you’ll need to create an OAuth member. If you’re using the Connect Widget, refer to Integrate using MX’s Connect Widget.

​
Credentials & OAuth

This section further details how OAuth works for the MXCU (OAuth) institution. When you select MXCU (OAuth) from search, or load the Connect Widget with it by configuring current_institution_code, you’ll see the following screen before going to the OAuth provider: Screenshot of oauth connection screen where you select log in For this test institution only, you must use the following credentials:
  • Username: multipleaccountowners
  • Password: testpassword
Then, you’ll end up on this page: Screenshot of oauth connection screen for authorization From here you can select Authorize to simulate authorization and success paths, and Deny to simulate an error path.
