Once you've defined variables in Requestly—whether global, environment, collection, or subcollection — you can reference them directly in your API requests. This allows you to dynamically inject values into URLs, headers, request bodies, scripts, and more.
Use Variables in API Requests
Step 1: Create or Open a Request
Create or open an existing request in the API Client.
Step 2: Replace Static Values
Replace static values with your environment variables using the {{variable_name}} syntax.
Step 3: View Variable Values
Hover over a variable to see its resolved value.
Test Your Setup
Step 1: Execute the Request
Click Send to execute the request.
Step 2: Verify Resolved Values
Check the resolved values in the Request Preview to ensure that variables are substituted correctly.
If a variable isn't resolving, verify that the variable name matches exactly (case-sensitive) and is present in the selected environment.
