I would like to suggest the possibility of create specific access tokens to retrieve data related with the Subscriptions APIs (Identity, Sales and Retail APIs) in order to increase the security of the personal data linked with registers and payments. As you can suppose, these are sensible data that require more careful management to avoid security holes.

Thank you for the suggestion! We are in the process of planning for the implementation of additional access tokens, and subscription specific API access is being considered in the planning phase.
