Api application status synchronization error in advertising office

Were lobsters. Our product is an advertising office to participate in the Tinkoff Bank partner program.

We have broken the synchronization of applications in one of the blocks of the system, we need help.

How it all works: https://miro.com/app/board/o9J_lfRI2Qo=/

Whats broken:

The synchronization between Datamind and the tracker has been disrupted. Datamind has 13,255 applications and 5,680 applications in the tracker. Probably something broke down when the same number of applications came in 3 weeks as 3 months earlier.

We are looking for an experienced developer with a qualified and suitable stack of technologies to help solve this error.

If you know how to help us, offer your price and the time it will be. If you are ANP or self-employed, report it separately, please.
