OAuth is an open authorization framework that lets one application access a user's data on another service without sharing the user's password. Instead of credentials, OAuth exchanges short-lived access tokens that the client presents to protected APIs.
Common OAuth Flows
- Authorization Code (3-legged): Browser redirects the user to log in → service returns a code → client swaps it for an access token.
- Client Credentials (2-legged): Machine-to-machine flow—no user approval; the client authenticates with its own key/secret.
- Device Code: Designed for devices without browsers—user enters a code on a separate screen to approve access.
Why Pair OAuth with Proxied?
- Anonymity & trust: Some APIs geo-restrict or throttle calls by IP. Routing token exchanges and subsequent API requests through Proxied's 4G/5G mobile IPs prevents location blocks and improves request reputation.
- Rate-limit resilience: Rotate IPs per token refresh or per request to avoid "429 Too Many Requests" errors during high-volume data pulls.
- Consistency for user flows: When an OAuth flow needs the same IP across redirects (e.g., during login approval), Proxied offers sticky mobile sessions so your client retains the same trusted carrier address until the flow completes.
