Nango
A unified API auth and data sync layer for connecting agents to external services. Handles OAuth 2.0, API keys, and token refresh for 200+ integrations. Gives agents authenticated access to Salesforce, HubSpot, Google, Slack, GitHub, and more without handling credential management directly. The agent proxy pattern: the agent calls Nango with a connection ID and action, Nango handles auth, calls the downstream API, and returns structured data. Removes the biggest operational burden in multi-service agentic workflows.
Viable option — review the tradeoffs
You need your AI agents to securely connect to 700+ external APIs like Salesforce, HubSpot, and Slack without building OAuth flows, token refresh, or credential storage from scratch.
Battle-tested scaling and retries work great for production; full 1:1 API passthrough aids debugging, but private/custom APIs need manual base URL and lack pre-built syncs.
Your agents require reliable tool calls to external services with per-user/org scoping, observability, and no credential leaks into LLM context.
Direct API access prevents normalization black boxes; scales elastically but requires custom logic for complex permissions—strong for multi-tenant agents.
Private API Gaps
Generic private APIs lack pre-built syncs, pagination, rate limits, and base URLs—must override manually or contribute to catalog; not for core use cases.
Secret Key Auth Only
All API calls require Nango Secret Key as Bearer token; expose it and your integrations are compromised—store securely, use env vars, never in frontend.
Self-hosting or Cloud Account
Nango runs as a service (Docker/self-hosted preferred for control); cloud is easier but may add latency/vendor lock for high-scale agents.
