Question

Is there any equivalent to signUpFeature for signin I m trying to add a token form field for my CAPTCHA token and this works fine for signup as I ve added the validator in the backend override but how do I do the same for signin

Hey < Noodles>

rp · Answer

You can t modify the formField for sign in at the moment But you can use the preApiHook to modify the request body and add the token to that

rp · Answer

And then read that token from the request body in the backend

Noodles · Answer

Okay cool considering that a new captcha token is generated on the frontend with every render how can I pass the token along to the preApiHook to then be passed to the backend

rp · Answer

which frontend SDK are you using

Noodles · Answer

Web JS

see this example of how to use the pre API hook https discord com channels 603466164219281420 1049600730236977202 1049970495078010910

Oh I see Alright so let s say my token is generated within login tsx how would I pass that same token to my frontend ts file where my frontend configuration is located sorry if these are dumb sounding questions just trying to grasp a deeper understanding of this

rp · Answer

where are you calling the supertokens web js function In login tsx or in frontend ts

Noodles · Answer

I m calling signIn from login tsx but supertokens is initialized in frontend ts

rp · Answer

right So you can add the preAPIHook to the sign in function itself

rp · Answer

see the link above

rp · Answer

it s calling createCode and to that function its giving the pre API hook You can do a similar thing for the sign in function call too
