Newoldstamp

Newoldstamp GraphQL API

The undocumented application GraphQL API that powers the Newoldstamp dashboard — signatures, departments, campaigns, segments, Google Workspace and Microsoft 365 deployment, and billing. Introspection is anonymously open; auth is a bearer access token from the signIn mutation. No public developer program.
