Before the app can communicate with the API, 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..."
Using an SDK is recommended. SDKs make the process of generating a token a lot easier and are probably available in the preferred programming language. This is covered in the next step.

Create a new API key

To use the API you need to generate a new API key. Please reach out to your Wpay representative who provides you with the API key.
Learn more about private keys, key-pairs, and JWT in the in-depth guide on authentication.

Summary

In this step:
  • Learned about API authentication.
  • Created a new private key for the API.
  • Stored this API key in a secure place where the app can access it.
