@agritheory I remember this, the create_contact fails to set phone no and gives error if the phone no from shipstation has extension ext in it, as the Options for field is set as Phone, it validates phone number here. To solve this issue we either need to parse phone no to remove ext from the data we are getting from shipstation or we can customize and remove Options Phone from the field. Let me know your thoughts on this.
