Hi all, I'm going through implementing a custom UI for Kratos and it's going quite well (everything appears to be working). However I'm not sure I've covered all of the expected query parameters that can appear in links that Kratos generates. For example, many of the URLs are expected to take a

flow

or

id

parameter for a flow id. I've been referencing the pages from the react implementation (https://github.com/ory/kratos-selfservice-ui-react-nextjs/blob/master/pages/registration.tsx) to see which additional query parameters are expected (such as

return_to

, etc.). It appears there are some gaps though. For example, when kratos sends a verification email, the link contains a

code

parameter which I'd like to autofill when given. This parameter does not appear in the reference app and I haven't been able to find any docs for it. I'm concerned I might be missing important parameters that appear on other flows. Is there documentation for the expected set of query parameters that can appear in links generated by Kratos that must be supported by the frontend? If not, is there a place I should look in the code to make sure I have all the bases covered?

@bland-eye-99092 Do you know the status of code in our reference apps or can you help out? here are the docs fwiw but you probably seen them already: https://www.ory.sh/docs/kratos/self-service/flows/verify-email-account-activation

The

code

query param is just used by Kratos directly, as the link in the email should point to your Kratos instance (not your own UI). Kratos will then redirect the user’s browser to your UI with a

flow

parameter set so you can fetch & render the flow. The

code

is then “pre-filled” in the

ui

nodes returned by Kratos, via the

value

attribute. If you implemented rendering the nodes with all it’s attributes this should just work. The docs could be a bit clearer on this, for sure.

Ah I should've looked more closely at the url to see it was pointing to the kratos backend - thanks for explaining that. It is indeed pre-filling as expected
