Do I need an API gateway for partner integrations?

Not always—but often yes if partner integrations are external, numerous, or need strong control.
Use an API gateway if you need:
- Authentication/authorization for partners
- Rate limiting / throttling
- Request/response transformation
- Logging, monitoring, and audit trails
- Versioning and routing
- Centralized security policies
- A stable public endpoint in front of internal services
You may not need one if:
- You have only a few trusted partners
- Integrations are simple and low traffic
- A single backend service can safely expose the needed APIs
- You’re okay managing security and routing inside the app
- A lighter approach like a reverse proxy or B2B integration service is enough
Common pattern
For partner-facing APIs, many teams use:
- API gateway in front
- Dedicated partner API layer or BFF
- Internal services hidden behind private networks
Rule of thumb
If partners will call you directly over the internet and you care about security, observability, or governance, an API gateway is usually worth it.
If you want, I can help you decide based on your setup (number of partners, traffic, auth model, and whether partners need sync or async integrations).
