How to Test API Calls Before Integration

Before connecting Enrich Layer to your tools or workflows, testing your calls in isolation lets you confirm everything is working, understand how credits are used, and get familiar with response structure.

What you'll need

• An Enrich Layer account
• Your API key (found in your dashboard)
• A tool to make HTTP requests — Postman, curl, or a simple Python/JavaScript script

Testing in Postman

1. Open Postman (desktop app or web version)
2. Create a new request and set the method to GET or POST depending on the endpoint
3. Enter the API endpoint URL
4. Under the Headers tab, add your Authorization: Bearer YOUR_API_KEY header
5. Click Send

A successful call returns a JSON response with the enriched data.

Things to keep in mind

• Credits are deducted for valid results, even in test mode
• If you use placeholder or invalid input (e.g. a fake LinkedIn URL), you may get empty or incomplete responses — no credits are charged for those

Example test cases

• Enrich a single LinkedIn profile
• Search for people with basic filters (job title + country)
• Test edge cases like invalid input to see how the API responds
