Skill: Custom Connectors
When to Use
Trigger when building, configuring, or debugging custom connectors — reusable API wrappers that expose REST APIs as Power Platform connectors for use in Power Automate, Power Apps, and Copilot Studio.
When to Use Custom Connectors vs Alternatives
| Scenario | Use | Why |
|---|---|---|
| Standard connector exists | Standard connector | Zero maintenance, Microsoft-supported |
| REST API used in one flow only | HTTP action in Power Automate | Simpler, no connector overhead |
| REST API used across multiple flows/apps | Custom connector | Reusable, typed, discoverable |
| REST API with complex auth (OAuth 2.0) | Custom connector | Auth handled once, shared across all uses |
| High-volume API calls needing throttling | Custom connector + Azure APIM | APIM handles rate limiting, caching, monitoring |
| On-premises API (no public endpoint) | Custom connector + On-premises Data Gateway | Gateway bridges private network |
