Sandbox - Invoice refund error

Trying to issue a refund to an invoice in our sandbox. It appears all invoices have this issue.

Sandbox app id: sandbox-sq0idb-9OyqW_2Obzu1AeWT2tbAIw

Maybe a CORS issue since the request is forwarding to the main domain:

Thank you

Are you trying to refund the payment in the sandbox seller Dashboard? If so that is a known limitation in Sandbox. Payments in sandbox can only be refunded by the API at this time. :slight_smile:

Yes, attempting through the Dashboard UI.

Thank you for the quick response!

Is there a list of known limitations or issues anywhere?

Yes, our Sandbox limitations section of our docs has all the known limitations. :slight_smile:
