Question: How to create, update or append a contact with a user’s input values Created contacts should appear on the Dash in Customers & Leads > Contacts right? But nothing has worked yet even at a basic level ▶ Attempts (all failed!) : Many thanks!

[image] onemoretime: you have your own custom field values and are trying to handle them using extendedFields, right? yes So, all the steps worked except just the appending part, which I kept manipulating, and I GOT IT! For your guidance @onemoretime ありがとうございます! The full the working code f…

[image] Gideon_Skarzgard: Created contacts should appear on the Dash in Customers & Leads > Contacts right? Correct :slight_smile: I noticed the second example suggested contacts.jsw, however .jsw is deprecated, and the code within the suggestion is for a .web.js file (which is what we enco…

Thanks Noah. I tried this, had nothing & spent a while debugging with GPT, no related errors are even showing. I feel completely clueless😓

Can you share a link to the site?

Hi, @Gideon_Skarzgard !! Just to confirm, have you installed the SDK as Noah mentioned? I think he probably meant that you need to search for and install "@wix/crm" and "@wix/essentials" via npm. :innocent:

Heyy @onemoretime & @noahlovell , I found my error; a rookie mistake! Your related code was correct! even some older attempts.

Thanks:) Based on your tips, I split the code to the front & backends & tried several iterations. Still nothing //backend code import { contacts } from '@wix/crm'; import { auth } from '@wix/essentials'; // Required for elevated permissions if needed export async function updateContactCustomField(c…

Have you already checked the logs in detail to determine exactly how far the process has succeeded? :upside_down_face:

This is the one console error I got, which I’m not knowledgeable enough to interpret, but it seems the backend function hasn’t worked even at a basic level. If this doesn’t help find the issue, pls let me know how I can make it easier for you [Screenshot 2025-10-14 203621] GPT just says I should …

Yeah, that’s a very simple mistake. :kissing_face_with_smiling_eyes: The issue is that the backend function updateContactCustomField is still written in the old .jsw format, even though it’s being imported on the frontend as a .web.js module. This is a very common mistake. In other words, you can e…
