How To Send Data From Checkout UI Extension to Backend?

[Joy_Matubber]

For an app, I need to send some data in the backend from the Checkout UI Extension to store them in the app database. I'm using the Shopify Remix template. How can I send data in backend?

Hello,

I  just want to fetch data from my backend  to customer ui extension on profile target  so how can i do that thing.

When I used npm run dev command, I used the tab which created the url accordingly but I am getting 302 status code which is redirecting me to the login page while I have also passed the session token in the header.
Please see the screenshot below of my code

also see the screenshot below of my response

Thank you

I've done something very similar to you. Are you sure the address in your fetch call is correct?
How do you digest the token at the request route? I am struggling with this.
