Hi,
Thank you for reaching out to us.
As per this
guide , if your access to the customer account is through a manager account, this header is required and must be set to the customer ID of the manager account.
To elaborate, if your
OAuth2 credentials were generated using a user / email address associated to your manager account, you will need to specify that manager account's ID as the login-customer-id. Let me know how this goes on your end.
Best regards,
