I have an App in development, and I have the APIs for get service appoinements and history setup repair orders, show up in my subscription information via the https://subscriptions.fortellis.io/v1/solution/subscriptions endpoint. However, when I try to access these API with the appropriate authentication headers and subscription ids, I am consistently getting 403 errors. More information on the error is given below:
