hey guys, is there some mechanism that allows to make refresh token request if I got a special error and repeat the initial request after that ?

Yes. Ktor Auth

Use a custom provider

[ribesg]

You have 2 options I think

[ribesg]

if it’s a JWT token or similar, you can read it and see if it’s still valid. If it’s not, refresh it in your implementation of addRequestHeaders before adding it

[ribesg]

The other option is to have 2 providers, one which always adds the auth headers to requests, and the other which only exists to handle 401

[ribesg]

See how it works https://github.com/ktorio/ktor/tree/master/ktor-client/ktor-client-features/ktor-client-auth/common/src/io/ktor/client/features/auth
