Accesstoken/refreshtoken API

While calling https://dev.abdm.gov.in/gateway/v0.5/sessions API,we get 2 tokens- accesstoken and refreshtoken.
To call remaining APIs, we need to add accesstoken in the header.When adding accesstoken in the header, the API response is ‘unauthorised’,
but adding refreshtoken the API response is correct.
So Which token should we need to use?

hey @ancya.ehk were you able to figure this out ?
