call onboarding API returned 401 code

[GavinSun]

Hi Support,

When I tried to call the onboarding API (sandbox), I always get this message, "status":401,"code":"9159","severity":"ERROR","message":"Token Validation Failed"

Could you please help to confirm if this onboarding API's Path and Endpoints is right? if it is right , why does it returned 401 ? I have added header "x-pay-token"

Hi @GavinSun,

This API documentation does not seem to be from Visa Developer. Can you please check the products on Visa Developer and let us know which product this API is part of? Thanks.
