OAuth Scopes
OAuth scopes are named permission strings that define what an access token is allowed to do, such as read contacts or write payments. During authorization, the user or admin approves requested scopes, and the issued token carries only those grants.
Technical Architecture & Deep-Dive
Providers document canonical scope names per API surface. Requesting excess scopes increases consent friction and breach impact. Service integrations should map each feature to the minimal scope set, store granted scopes with tokens, and reject API calls that exceed them.
Edge pipelines can enforce scope-like rules by exposing only specific operations per client token, even when upstream credentials could do more. This mirrors least privilege at the integration boundary.
Key Architectural Benefits
Implement OAuth Scopes at the Edge
Deploy lightweight API aggregation, edge caching, and secret injection in minutes without Docker containers or complex servers.
Frequently Asked Questions
Q:Can I change scopes without re-authorizing the user?
Generally no. New scopes require a fresh authorization. Plan scope needs up front to avoid disruptive re-consent flows.
Related Architecture Concepts
OAuth 2.0 is an authorization framework that lets an application obtain limited access to a user account on another service without handling the user password. The user approves requested scopes, and the application receives an access token it uses to call the service API.
The principle of least privilege states that every user, service, and credential should have only the minimum permissions required to perform its task. For APIs, this means using restricted keys, narrow OAuth scopes, and client tokens limited to specific endpoints.
An access token is a credential that authorizes calls to a protected API on behalf of a user or application. OAuth providers issue access tokens with a limited lifetime and scopes. APIs validate the token signature or call an introspection endpoint before executing the request.
A Client Token is a scoped, revocable authentication credential designed for frontend web and mobile applications. It grants permission to invoke specific edge API pipelines while enforcing allowed-origin domains and rate limits, safely abstracting sensitive upstream API secrets.
Ready-to-Use Edge Recipes
You should not store Salesforce credentials in React client code. Vault-inject OAuth or integration tokens at the edge; React calls one public client token URL. RealComposer Secret Vault injects headers on Cloudflare Workers so only your edge URL is public.
To solve how to connect stripe to retool securely, never execute unauthenticated requests or embed private tokens directly in client bundles. RealComposer acts as a sub-10ms edge gateway running on Cloudflare Workers that securely injects credentials from your Secret Vault, normalizes responses, and prevents unauthorized API usage. Route calls through your RealComposer edge URL to guarantee complete privacy, robust origin validation, and low mobile latency.
