Builder Connect Login

This tool focuses on the decision logic and data flows required to establish a secure login connection between a builder application and an identity provider. It accepts provider configuration, credentials, and endpoints and then simulates the OAuth 2.0 authorization code flow, producing a test authorization_code and a token response. It is aimed at developers integrating SSO, ISV partnerships, or multi-tenant architectures.
Conceptually, the tool validates inputs, constructs an authorization URL, computes PKCE parameters when enabled, and exchanges the code for tokens via the token endpoint. The outputs include access_token, token_type, expires_in, and optional refresh_token. It surfaces structured errors for invalid credentials, misconfigured endpoints, or provider errors, enabling rapid triage without involving live users.
Unique value lies in its ephemeral sandbox and environment presets (dev/stage/prod), PKCE support, and detailed error decoding aligned with OAuth 2.0 RFCs. Use cases include validating client_id/secret pairs, testing redirect_uri correctness, and auditing token lifetimes before production deployments. It benefits platform teams, integration engineers, and partner onboarding specialists.
