We should also review the onboarding process for products where this process can be different (STRR) and compare it with the standard API Client onboarding process. Identify any product-specific steps, prerequisites, or support procedures. Assess whether existing client-facing and internal documentation accurately reflects the actual onboarding process.

Note: The API process is documented (from a Registries staff perspective) [here](https://bcgov.sharepoint.com/teams/12339-RegistriesandDigitalServices/Shared%20Documents/Forms/AllItems.aspx?id=%2Fteams%2F12339%2DRegistriesandDigitalServices%2FShared%20Documents%2FRegistries%20and%20Digital%20Services%2FStrategic%20Services%20and%20Registries%2FStaff%20Information%20Centre%20Resources%2FSTAFF%20INFO%20CENTRE%2FResources%20to%20help%20with%20client%20questions%20%26%20issues%2FBusiness%20Unit%20Processes%20%2D%20API%20Request%20Management%2Epptx%201%2Epdf&parent=%2Fteams%2F12339%2DRegistriesandDigitalServices%2FShared%20Documents%2FRegistries%20and%20Digital%20Services%2FStrategic%20Services%20and%20Registries%2FStaff%20Information%20Centre%20Resources%2FSTAFF%20INFO%20CENTRE%2FResources%20to%20help%20with%20client%20questions%20%26%20issues).
