I have exactly same issue.
Validate endpoint is validating my TIN and BRN number and get 200 response. Btw `Validate` has to be GET not POST. you can check API documentation. And i tried sending wrong numbers, it sends 404, when correct combo you get 200.
When i submit a dummy document i get this error ;

"message": "The authenticated TIN and documents TIN is not matching "



i decided to develope a e-invoice tool and cannot do a full flow now
