:play_button: How to Apply for Access

Please follow the appropriate application process based on your current status:

  • New to the MSU API?
    If you do not yet have an API key, please apply through the API Access page.
  • Already have an API key?
    If you already hold an API key issued prior to June 8, please submit a separate request to have your existing key updated with the New Endpoint Permissions.

Once your application is reviewed and approved, we will update your API key permissions and notify you so you can begin development immediately.
