🚀 Ready to See Enrich Layer in Action?

If you’re new to APIs—or just new to Enrich Layer—this step can feel like a big one. But don’t worry: testing your first call is easier than you think.

Before you plug Enrich Layer into your tools or workflows, we recommend taking a moment to test things out in a safe environment. That way, you can:

  • Confirm everything is working correctly

  • Understand how credits are used

  • Get a feel for how responses are structured

Let’s walk through it step by step.

✅ What You’ll Need

To test API calls, make sure you have:

  • An Enrich Layer account

  • Your API key (get it from the Dashboard – see instructions)

  • A tool to make HTTP requests, such as:

    • cURL

    • A simple script using Python or JavaScript

Step-by-Step: Testing in Postman (No Code Required)

  1. Open Postman (you can use the desktop app or web version).

  2. Choose “New Request” and set the method to GET or POST (depending on the API you’re testing).

  3. Enter the API endpoint URL. For example:

  4. Under the Headers tab, add:

  5. Click Send to make the request.

If successful, you’ll get a JSON response with the enriched data.

⚠️ Keep in Mind

  • Credits are deducted even in test mode, as long as a valid result is returned.

  • If you’re testing with placeholder or low-quality input (like fake profile URLs), you may get empty or incomplete responses


    ), you may get empty or incomplete responses.

💡 Example Test Use Cases

You can try:

  • Enriching a single known public profile

  • Searching for people with basic filters (e.g. job title + country)

  • Testing edge cases like invalid input or missing fields to see how the API responds
