We do not recommend using two providers for the same service. Specifically, it is advised against using two repricing service providers simultaneously. However, your inventory management service should operate normally with our Repricing Central or BigCentral.
Simultaneous requests from two service providers for the same or similar data reports can lead to conflicts in adjusting prices and may exceed your SP-API's throttling limit. When you reach the request quota for your SP-API account, Amazon will deny requests for essential data until the hourly quota is under control. In essence, this situation can impact the response time of our services.
Therefore, we recommend revoking SP-API authorization for other service providers when you are ready to begin using our service.
