Customer API

[Madhav_netlynx]

Hi Shopify Team,

I am facing an issue with updating the phone number with /admin/api/2021-10/customers/customer_id.json on my settings page. Actually, It's updating a few of the phone numbers like +15999999999 and not updating a few which started +30. Can you please also tell me if there is any validation with the phone in Shopify customer API?

Thanks & Regards,

Yes, there is some base format validation.
Do you have an example (ideally a fake number) that doesn't work that you think should?
