Shopify Get Customer By Email

This action verifies whether a Shopify customer has historically used only a single first name across all of their saved addresses. It searches for the customer by email, retrieves their address list, extracts the first names, and confirms that they all match the customer’s primary first name.

Inputs

Name	Type	Description
Email	String	The email address of the customer to search for.
Domain	String	The shop’s myshopify.com subdomain (e.g., `your-store` for `your-store.myshopify.com`).
Token	Credentials	Shopify access credentials. Provide either a Basic auth header or a bearer token.

Outputs

Name	Type	Description
Success	Boolean	`true` if the customer has used only one first name across all addresses; otherwise `false`.
First Name	String	(Success only) The normalized first name used by the customer when all addresses match.
Customer	Object	(Success only) Full customer object returned by Shopify.
Error	String	(Failure only) Error reason: either `multiple names used for shipping` or `could not retrieve any customers with this email`.

Notes

Uses the Shopify Admin REST API version 2024-01.
If the customer has no addresses or multiple distinct first names, the action returns an error and success: false.
In case of network or API errors, the action returns success: false and includes the error message.
