I’m using this documentation to register a seller https://docs.tosspayments.com/guides/v2/payouts#%EB%B3%B4%EC%95%88-%ED%82%A4. After I send the request, I receive a JWE response. When I decrypt it, I get the following: "error": { "code": "FORBIDDEN_REQUEST", "message": "Not allowed request" } Please help me with this issue. Thank you all.
