</div>

is it possible to add a cutomClaim to the idToken so i can use it with third-part API from my next app

The scenario is that my logged in used should select and item and on the select event i will call my external API by adding the used choice.

The external API also use my auth0 token to determine the user.

Hi @ghomraniilyas ,

From what I understand, you want to add a custom claim to the access token which is issued to your API to authorize user for the requested resources. To do so, there is a [Post Login Flow](https://auth0.com/docs/customize/actions/flows-and-triggers/login-flow/event-object) (Actions feature) with a method: `api.accessToken.setCustomClaim(name, value)`.

Hope this helps, please let us know any questions!

Thank you for your response @marcelina.barycka i want to add the custom claims after the user make a choice in my app (NextJS app the value is the value of the choice)

So i want to change the token from my app goes to Auth0 and returns to my next app with the new token so i can send it to third-part API

The flow is described in this doc - [Redirect with Actions](https://auth0.com/docs/customize/actions/flows-and-triggers/login-flow/redirect-with-actions) (redirect to an external page during the login flow and use the gathered from user data to add custom token claims that will be later returned to your app).
