Service-to-Service flow

The service-to-service flows is for data exchanges that don't require the presence of a (human) user. Credentials that are presented during this flow are typically subject to legal organizations (e.g. registered care organizations).

This flow uses a custom grant type called vp_token-bearer. Presentation requests always and only target organization wallets.
