Error message

Customer email conflicts with existing customer ID %s.

Common causes

• Another customer already uses this email. Email addresses are unique regardless of letter case, and archived customers still count.
• You're updating a customer's email to an address that another customer already uses.
• Multiple requests to create a customer with the same email address were made.
• A third-party integration you authorized may be trying to create a customer that already exists.

Troubleshooting

• Get the ID of the existing customer from the error detail and use that for subsequent requests.
• To find the existing customer, list customers using the email query parameter with status=active,archived. Archived customers aren't returned by default.
• If the existing customer is archived, set its status to active to use it again.
• Don't send multiple requests to create a customer with the same email address.
