Providers API
List
GET /providers/get/ returns the configured provider properties.
Edit provider restrictions
POST /providers/edit/ requires a JSON body containing id.
The public endpoint updates the supported allowed-service and restriction properties. It is not a generic WordPress user editor.
Edit provider service settings
POST /providers/edit/service/?serviceId=s_example&providerId=12
Use this endpoint only for provider/service properties accepted by the current public route. Service-scoped duration and buffer settings must be changed on the service, not as provider overrides.
