Kind of want to follow-up on this because it is still unclear how the flow works. I'll go through my findings with the scenarios.
1. User creates an account never placing a guest order previously.
Here, it is a brand new account using customerCreate. As stated in the documentation, "if the mutation is successful, then a welcome email is sent to the customer with the information that their account has been activated." This happens, and a customer object is returned after calling the mutation. The account is activated automatically.
2. User creates an account with a guest order existing for that email
We run customerCreate for an existing email, however this time, customer is NULL and doesn't return customerUserErrors stating that an email has been sent. The activation email is sent though. Here I guess I can just assume when customer is null that the activation email is sent, but not sure if this is intended.
Moreover, the activation form, I'm using the shopify theme ( not headless ) requires a password to activate. So why does customerCreate require a password? I would understand if the user had to repeat and confirm their password, but customCreate password can be different from the Activation password.
I can make this flow work as long as I can distinguish activation by email from automatically activated accounts.
*note that these guest orders were created manually in the admin, so not sure if this is what is affecting it.
3 User create an account that exists
If the account was previously made, customerCreate returns customer NULL. I believe we should be getting the customer object or at least a customerUserErrors that the customer has already been created?
