When our shop use Multipass, can we synchronize EC site (shopify) and original web site?

Is it possible to receive the customer_id as a callback from the EC side when the new registration on Shopify's Multipass?

Hi Yuno-7,

Shopify does not directly provide a callback with the `customer_id` when a new registration is made via Multipass. When you create a Multipass login for a customer, you're essentially creating a new customer record in Shopify. The `customer_id` is generated by Shopify and is not directly accessible during the Multipass login process.

If you need to keep track of the `customer_id` for new customers registered via Multipass, you would need to use Shopify's Admin API. You could create a process on your server that periodically polls Shopify for new customers (using the /admin/api/2023-07/customers.json endpoint, for example) and then updates your original website with the new `customer_id` values.

Hope this helps!

Hi, Liam

I am trying to set up our shop with multipass login. 

I have the same issue with this question. Thanks your reply on this question.

But, I got one problem.
I tried to login with Multipass login process after creating a customer process on my server with Customer Create API . But it returns error which is email duplicated. Do you know what the reason is? I used email and multipass_identifier with creating a customer, email and identifier variables with multipass login.
