Amazon Seller
Org-level connection
Amazon Seller is connected once at the org level by an admin. The credential is shared across all groups that have been granted access — individual team members don't need to connect their own accounts.

Create a developer profile if you don't have one
In the SP-API console, register your application and generate LWA (Login with Amazon) credentials
Complete the OAuth self-authorization flow to obtain a refresh token for your own seller account

Troubleshooting
"Invalid API key" or "Unauthorized" error
Double-check that you copied the full key without any leading/trailing spaces. Some platforms show a truncated preview — make sure to copy the full token. If the key was generated with restricted scopes, verify it includes the permissions listed above.
Connected but Claude can't access data
Check that your group has been granted access to this integration in On Belay → Groups → [your group] → Integrations. Also verify the specific scopes your group is permitted to use match what your query requires.
The key expires or stops working
Some API keys have expiration policies. Generate a new key in Amazon Seller and update it in On Belay → Integrations → Amazon Seller → Update key. Consider creating a dedicated service account or machine user for On Belay so the key isn't tied to a personal account.
