Troubleshoot API Transmissions

Troubleshooting API transmissions involves verifying the accuracy and efficiency of API calls made to Amazon Vendor Central. This process is crucial for identifying and resolving errors that may arise in transaction processing.

• GET Transactions: Returns an immediate, synchronous response for checking accuracy against request parameters. Errors trigger messages explaining failure reasons.
• POST Transaction: Vendors use APIs like Direct Fulfillment Transaction Status to track asynchronous processing, identified by a unique transaction ID (GUID).
• Error Handling: Vendors should monitor transaction status via APIs to ensure successful processing, providing error details for corrections if necessary.

Checking if changes are reflected in Vendor Central is advised, and troubleshooting tools aid in maintaining compliance with Amazon’s performance policies.
