Endpoint: https://einvoiceapiuat.impact.gr/Authentication/refresh

Request Payload: “[token value from the refreshToken object]”

The response will be similar to the one received when issuing the access token. This request needs to be authenticated.

Insert your "accessToken" value in the "Authentication" param on the header of the POST call.

All requests to the API need to be authenticated by implementing JWT Bearer token authentication.

For example, to issue an invoice using the endpoint: https://einvoiceapiuat.impact.gr/invoice/json, the corresponding header would look like this:

Key: “Authorization”
Value: "Bearer<your_RefreshToken_here>"
