Update customer is a WordPress ability from LatePoint — usable via Easy MCP AI, which connects Claude, ChatGPT, and any AI assistant to your site.
Install Free Plugin →Update customer
WriteUpdates one or more fields on an existing customer profile.
Requires the LatePoint plugin on WordPress 6.9+ (the WordPress Abilities API is only available from 6.9 onward). All abilities also require the site's 'latepoint_abilities_api' master toggle to be enabled; write abilities additionally require the 'latepoint_abilities_api_edit' setting, and destructive abilities additionally require the 'latepoint_abilities_api_delete' setting. Each ability further requires the current user to hold the matching LatePoint capability (e.g. 'booking__view', 'customer__edit'), and some abilities also verify the user is allowed to act on that specific record.
What it does
This ability updates an existing customer record by ID, changing only the fields explicitly supplied in the request (first name, last name, email, phone, or notes) while leaving all others untouched. Each provided value is sanitized before being saved. It confirms the customer exists and that the current user is allowed to edit that specific record before applying changes, then returns the refreshed customer profile.
