Before your application can communicate with the API you will need to create a new API key. The API handles authentication using a signed JSON Web Token (JWT) which is passed in a HTTP header.

curl -X GET https://api.example.gr4vy.app/transactions \
  -H "authorization: bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIi..."

We recommend you use an SDK. Our SDKs makes the process of generating a token a lot easier and is probably available in your preferred programming language. We will get to this in the next step.

Create a new API key

To use the API you will need to generate a new API key. Please reach out to your Wpay representative who will provide you with the API key.

Learn more about private keys, key-pairs, and JWT in our in-depth guide on authentication.

Summary

In this step you:

  • Learned about API authentication.
  • Created a new private key for the API.
  • Stored this API key in a secure place where your application can access it.
