The API functions as follows -

If you try registering an identifier that exists in a different source, a new source account is added to the existing account. Details of each source account will be maintained separately.
In a source account, identifiers should be unique - no two customers can have the same identifier.
You cannot update existing customer details with this API. To update customer details, use the customer update API; to update identifiers, use the Update Identifier API.

Note

Hovering over the profile picture on the Member Care home page shows the customer's account ID.
The last part of the URL containing numbers represents the customer ID, or ID. The system generates this internal ID when it registers the customer. For example, the URL https://{host}/member-care/ui/customer/177217505, 177217505 is the ID or the customer ID.
The mandatory attributes for customer registration are determined by the configurations set in Organization Settings > **Miscellaneous **> Registration Configuration. Be sure to check your organization's configurations before using this API. For more details, refer to Setup Customer.
Extended fields are mapped to vertical IDs, which are then mapped to organization IDs.

📘
Extended Fields are proposed fields used to standardize input values and keys across organisations (unlike custom fields that have no control in input values). Platforms back-end team controls the field names, data-types, enum values, and scopes of extended fields. Extended Fields are created at customer level, transaction level, and transaction line-item level. Examples of customer level extended fields are age_group, preferred_store, gender, and nationality. Extended fields are either associated with verticals or a generic category (available for all orgs). To know the list of extended fields enabled for an org, use GET v2/extendedFields API.
