Issue with Amazon Sync: InvalidInput Error
When using Amazon Sync, you may encounter an error message that looks like this:
CreateFeed: { "errors": [{ "code": "InvalidInput", "message": "Invalid request parameters", "details": "" }] }
Why am I seeing this error?
This error typically occurs when there is an issue with your Amazon account configuration in Amazon Seller Central, most commonly related to payment or billing information.
Unlike other feed errors (e.g., missing attributes or mapping issues), this error usually happens before the feed is fully processed, which is why no detailed field-level error is returned.
Most Common Cause
Missing or Invalid Payment Information
Expired or invalid credit card
Incomplete billing details
Issues with your charge method
👉 This is the most frequent cause of this error
Other Possible Causes
Account not fully activated or under review
Marketplace not properly enabled
Temporary Amazon system issue
How to Fix It
1. Check Your Payment Method
Go to Settings → Account Info → Charge Methods
Make sure your credit card is:
Active
Not expired
Properly set as default
2. Verify Account Status
Check if your account is fully active
Resolve any notifications or alerts in Seller Central
3. Wait for Account Activation (if new account)
If your account is newly created or recently updated
Allow 24–72 hours for Amazon to complete verification
4. Retry the Feed
After fixing the issue, resend the feed from ExportYourStore
Important Notes
This error is usually not related to product data or mapping
If it were a feed issue, Amazon would return a specific attribute error
This error often appears when Amazon blocks the request at account level
