Create a widget for a location, or change an existing one's title and settings. Without unique_id a new widget is created; with it, that widget's widget_title and widget_options are replaced (its style stays). Leaving either field out clears it. Returns the widget's unique_id, which goes in the embed code. Creating a widget counts toward your plan's widget limit (402 when reached); the location needs an active widget add-on (400 otherwise).

Prerequisites: a bearer token, the location's store_id, a style id (widget_type_id) from List widget styles, and to edit, the widget's unique_id.

Authentication: Partner or Account token. store_id must be inside your own account tree (a Partner token reaches any location under the partner, an Account token only its own); otherwise 422. To edit, unique_id must be one of your widgets.

Rate limit: none.
