Quick Start

The Stacksync API Proxy is a unified, secure gateway that simplifies how you interact with third-party SaaS APIs like Salesforce, Airtable, and Attio.

Instead of building complex custom integrations, handling OAuth tokens, refresh flows, API rate limits, and bulk operation logic, you send requests to Stacksync's standardized endpoints. We handle the complexity and forward the request to your destination app, returning the response directly to you.

Why the API Proxy is useful

No auth or token hassle: Connect once with OAuth and use a single stable service token instead of managing app-specific tokens, refresh logic, or rotating secrets for every API.
Future‑proof: When an external API changes auth or versions, you update the connection in Stacksync instead of touching every app and script that calls it.
Secure by design: Stacksync stores and rotates underlying app credentials, so you never pass raw SaaS keys around in your app or copy them into scripts.
Consistent calls across tools: Call https://<region>.api-proxy.stacksync.com/v1/proxy/... for any supported app instead of learning each vendor’s base URLs, versions, and quirks.

When to use it

You’re doing one‑off or low‑volume operations (triggering workflows, special updates, admin actions) that don’t warrant a full continuous Stacksync Sync. If you need to read or write large volumes of data, use Stacksync Syncs instead so Stacksync can handle data movement, retries, and rate limits at scale.
You want to call your SaaS APIs (e.g. Airtable, Salesforce, HubSpot, etc.) from a backend service without managing each API’s auth yourself.
You’re building internal tools (Retool, low‑code, custom dashboards) that just need a simple HTTP endpoint and a bearer token.

Use Stacksync Syncs when you need ongoing, high‑volume, data synchronization; Use the Stacksync API Proxy only when you need direct, on‑demand, low-volum API access.
