This authorizes Stellar Support to read your Vendor Central data through the Selling Partner API — purchase orders, shipment confirmations, invoices and their transaction status — so your procurement flow can be tracked without exporting anything by hand.
You will be sent to Amazon Vendor Central to review and approve access, and you will need to be signed in as a user who can authorize applications for your vendor group. Nothing is granted until you approve it on Amazon's own screen.
Ready
Start authorization when you are ready.
We will generate a one-time state token, send you to Amazon, and then finish the handshake on the registered callback page.

What happens next
Three-step handoff
Stellar Support creates a secure authorization session for your browser.
Amazon Vendor Central asks you to approve access for the registered app.
Amazon sends a short-lived code back to our callback page, where we exchange it for a refresh token.
Authorization is granted per vendor group, and covers every vendor code inside that group.
Security note
What we store
Short-lived OAuth state values for CSRF protection.
The partner ID Amazon returns once the flow starts.
The resulting refresh token, stored encrypted in Google Secret Manager.
Access tokens are short-lived runtime credentials. The long-lived refresh token is the one we persist so Stellar can request fresh access later.
