Here is my request

09/08/2022, 1:56 PMCould you post the validation error as well?

09/08/2022, 2:03 PMIt seems that you are sending the request from a browser? We highly advice against that, as that opens you up to a whole host of security issues.

09/08/2022, 2:07 PMYes ,What is the best way to update the traits.

09/08/2022, 2:08 PMWell, if I understand your situation correctly, you have a service running somewhere that has a URL that is called by Ory Kratos after a user logged in, correct? You would then call the kratos API from that service (not a browser) to update the traits.

09/08/2022, 2:12 PMI have selfhosted kratos as a mean of authentication with a react app on the side.
Currently everything is working fine.
I would like to check if it's the first time the user login so I can show a different UI.

09/08/2022, 2:15 PMI have added a trait on kratos schema called

bland-eye-99092
09/08/2022, 2:19 PMYes, but for that you will need a separate service running somewhere to update the trait. It can’t be a browser, because you should not call the admin API from a user’s browser.

09/08/2022, 2:20 PMIs there a way I can update a trait from kratos config in webhook ?

bland-eye-99092
09/08/2022, 2:23 PMWell yes, just as I described: You need a service that runs somewhere on the internet. You register the service as an after login webhook. Once you receive the call you then go ahead and call the Kratos Admin API from this service to update the trait. But you definitely need a separate service (for example written in JavaScript, Go, etc.) that handles this as it can not happen from a browser.

09/08/2022, 2:31 PMI don't see any example when external service outside service is called in webhook here.😔

09/08/2022, 3:28 PMHere for example: https://www.ory.sh/docs/kratos/hooks/configure-hooks#webhooks
For your case (with some annotations):

OPTIONALcan_interrupt: true _# You Probably want to set this to false_auth:type: _# Can be one of 'basic_auth' or 'api_key'_config: _# Additional auth config for the hook.

09/09/2022, 2:01 PMThanks @bland-eye-99092 I got it working on a separate service.
Is there a way to set default value to a traits in the schema ?
