## **Instructions to Use Postman Collection** 



1. Juspay uses HTTP Basic Auth for authentication. API Key is used to authenticate the Server-to-Server API Calls. API Key can be generated through the Juspay Dashboard. Navigate to `Login>EC Operations>Settings>Security>Create API Key`
2. Add your API Key in Postman. Select `Juspay APIs - OpenAPI 3.0 → Authorization`
   
   * Set 'Type' = Basic Auth
   * Set 'Username' = <Your_API_Key>
   * Set 'Password' = <Blank>
3. You may use the_Variables_  tab to store and reuse values in Postman. By storing a value as a variable, you can reference it throughout the collection.
