Customer Custom Attributes API

Upsert customer custom attribute

POST

 /v2/customers/{customer_id}/custom-attributes/{key}

Use this endpoint to set the value of a custom attribute for a specified customer profile. A custom attribute is based on a custom attribute definition in a Square seller account, which is created using the CreateCustomerCustomAttributeDefinition endpoint.

To create or update a custom attribute owned by another application, the visibility setting must be VISIBILITY_READ_WRITE_VALUES. Note that seller-defined custom attributes (also known as custom fields) are always set to VISIBILITY_READ_WRITE_VALUES.
