Due to Amazon FBA access changes, using MWS credentials has proven more successful than AWS keys to connect your Amazon FBA account to Orderlytics.
Please use the following steps to connect your FBA account:
Click on the "Sign up or manage Amazon MWS" link
Login to your Amazon Sellers account
On the Users Permissions page scroll down to Third Party Developers and Apps button
On Manage your apps page select the "Authorize new developer" button
Enter the following information: Developer Name - Real Buzz Media and Developer ID - 006439491615 (note: Real Buzz Media is the parent company of Orderlytics. Our Amazon developer account is listed under RBM.)
7. Accept the Amazon MWS license agreement to authorize Real Buzz Media to access your Sellers account.
8. The Amazon MWS authorization page provides the Seller ID and MWS Auth Token. Copy the Seller ID, Marketplace ID and MWS Auth Token
9. Enter the MWS Auth Token information in the Orderlytics Fulfillment Account section. (Note: When using MWS credentials leave Secret Key field blank)
10. Click Save. Account inventory and orders should be available within 15 minutes.
