Customer information pre-population reference

Reference for the customer, billing, and shipping parameters used to pre-populate checkout fields.

If you’re considering pre-populating customer info on the checkout, the API and Single Sign-On (SSO) offer more power and flexibility. All of the parameters below are optional and can be passed in individually.

Parameter	Details
`customer_email`	Notes: Must be a properly formatted email address.
`billing_first_name`<br>`shipping_first_name`	Notes: No validation is performed on values passed in.
`billing_last_name`<br>`shipping_last_name`	Notes: No validation is performed on values passed in.
`billing_address1`<br>`shipping_address1`	Notes: No validation is performed on values passed in.
`billing_address2`<br>`shipping_address2`	Notes: No validation is performed on values passed in.
`billing_phone`<br>`shipping_phone`	Notes: No validation is performed on values passed in.
`billing_company`<br>`shipping_company`	Notes: No validation is performed on values passed in.
`billing_city`<br>`shipping_city`	Notes: No validation is performed on values passed in.
`billing_postal_code`<br>`shipping_postal_code`	Notes: No validation is performed on values passed in.
`use_different_addresses`	Notes: To pass in both shipping and billing information, this must also be passed in with a value of `1` so the checkbox on the checkout is properly checked to display both the billing and shipping fields.
`billing_region`<br>`shipping_region`	Notes: Accepts 2-character ISO codes for the state or province of the country determined by the customer’s IP address, unless a country is specifically set using pre-population.
`billing_country`<br>`shipping_country`	Notes: Accepts 2-character ISO codes for the country.
