What it does
API contract testing, authentication flows, rate limit handling, and error scenario coverage for n8n integrations with external services. Use when testing n8n node integrations.
n8n Integration Testing Patterns
<default_to_action> When testing n8n integrations:
- VERIFY connectivity and authentication
- TEST all configured operations
- VALIDATE API response handling
- CHECK rate limit behavior
- CONFIRM error handling works
Quick Integration Checklist:
- Credentials valid and not expired
- API permissions sufficient for operations
- Rate limits understood and respected
- Error responses properly handled
- Data formats match API expectations
Critical Success Factors:
- Test in isolation before workflow integration
- Verify OAuth token refresh works
- Check API version compatibility
- Monitor rate limit headers </default_to_action>
Quick Reference Card
Common n8n Integrations
| Category | Services | Auth Type |
|---|---|---|
| Communication | Slack, Teams, Discord | OAuth2, Webhook |
| Data Storage | Google Sheets, Airtable | OAuth2, API Key |
| CRM | Salesforce, HubSpot | OAuth2 |
| Dev Tools | GitHub, Jira, Linear | OAuth2, API Key |
| Marketing | Mailchimp, SendGrid | API Key |
Authentication Types
| Type | Setup | Refresh |
|---|---|---|
| OAuth2 | User authorization flow | Automatic token refresh |
| API Key | Manual key entry | Manual rotation |
| Basic Auth | Username/password | No refresh needed |
| Header Auth | Custom header | Manual rotation |
Connectivity Testing
// Test integration connectivity
async function testIntegrationConnectivity(nodeName: string): Promise<ConnectivityResult> {
const node = await getNodeConfig(nodeName);
// Check credential exists
if (!node.credentials) {
return { connected: false, error: 'No credentials configured' };
}
