Getting notified about System Integration/APP selection

buddy01

Hi Team,
I have two questions:

When a taxpayer logs into our System Integrator software with their TaxMaxPro credentials, is there a way to know if they have indeed selected us as their SI? When I call the GET Entity endpoint of the taxpayer, I don't see details in the API response indicating whether we are the SI, so we know whether to block their access or allow them log in and use our platform.
The same question as above, but for logging into an APP software. I heard it mentioned once that FIRS will block the login if we are not selected as the taxpayer's APP. It will be good to get some data to test this and the scenario above as well.

Dear buddy01

Thank you for your response.

All requests made in your questions are exclusively for Access Point Providers (APP). The entity endpoints are exclusive to APP. System Integrators are expected to work directly with taxpayers by using their credentials or alternatively, enable themselves as taxpayers for e-Invoicing.
