Example : Register New contacts at website X Thet registered at website Y

Hallo Wixers I just Wrote code thet auto register users as contacts in website X (mother website) from website Y (daughter website)

Mother website - Recive contacts with Http POST , and save them with WIX BACKEND CRM

Creat new Backend file name - http-functions.js

Add the next code:

import { created, serverError } from 'wix-http-functions';
import wixCrmBackend from 'wix-crm-backend';

export function post_addContact(request) {
    let options = {
        "headers": {
            "Content-Type": "application/json"
        }
    };
    return request.body.json()
        .then((body) => {
            return wixCrmBackend.createContact(body.ans)
                .then((contactID) => {
                    return contactID;
                }).catch((errr)=>{console.log(errr);});
        })
        .then((results) => {
            options.body = {
                "inserted": results
            };
            return created(options);
        })
        .catch((error) => {
            options.body = {
                "error": error
            };
            return serverError(options);
        });
}

Daughter website - When Contect Created - > Add a tag, and send it to the Mother website.

Creat new Backend file name - events.js

Add the next code:

**you just need to change 2 CONST:

1 - the ID of the tag

2- your Domain

import wixCrmBackend from 'wix-crm-backend';
import wixFetch from 'wix-fetch';

const TAGID = "SomeTagId" //Need to change this ID of the TAG
const DOMAIN = "https://www.yourdomain.com" //Need to change Domain
export function wixCrm_onContactCreated(event) {
    const contactId = event.metadata.entityId;
    
        return wixCrmBackend.contacts.labelContact(contactId, [TAGID]) 	
            .then((contact) => {
                return wixCrmBackend.getContactById(contactId).then((ans)=>{

                console.log("contact", ans);
                return wixFetch.fetch(DOMAIN  + "/_functions/addContact/", {
                    method: 'POST',
                    headers: {
                        'Content-Type': 'application/json'
                    },
                    body: JSON.stringify({
                        ans
                    })
                }).then((httpResponse) => {
                    if (httpResponse.ok) {
                        console.log("Post ok");
                        return httpResponse.json();

                    } else {
                        console.log(httpResponse);
                        return Promise.reject("Fetch did not succeed");
                    }
                });
             })
       })   
}
