PolySign OAuth Scopes

OAuth 2.0 derived

PolySign publishes 1 OAuth 2.0 scope via the clientCredentials flow. Scopes are the fine-grained permissions an application requests at authorization time to act against the PolySign API on a user’s behalf.

Tokens are issued from /v1/auth/token.

This index is generated from the provider’s OpenAPI security definitions (and, where available, its documented scope reference) and refreshes on every APIs.io network build. Browse every provider’s scopes at scopes.apis.io.
