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.mattildapayments.com/transactions \
  -H "authorization: bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIi..."
