Update phone number
This endpoint updates the editable attributes of a phone number you own. Currently this is the nickname — a short, human-friendly label (e.g. “Sales line”, “Support — US”) shown next to the number across the dashboard. Only the owner of the number can update it. Numbers shared with you (granted) display the nickname but cannot be changed by you.

Path Parameters

integer
required
The unique identifier of the phone number to update

Body Parameters

string
A short label for the phone number. Maximum 50 characters. Send null or an empty string to clear it.

Response

The updated phone number
The nickname is the same label you can set in the dashboard. It is returned by the phone number listing endpoints (GET /user/phone-numbers/all, GET /user/phone-numbers/sip-trunks), so other resources that reference a number by phone_number_id can resolve its nickname from there.
