WasenderApi WhatsApp API

Create or Update Contact

Contacts

PUT/api/contacts

Creates or updates a contact in the session's address book.

Create or Update Contact

This endpoint allows you to manage contacts associated with the WhatsApp session. If you provide a jid that does not exist in the session's contacts, a new contact will be created with the provided fullName. If the jid already exists, its name will be updated.

The optional saveOnPrimaryAddressbook parameter can be used to sync the contact to the primary address book of the device running WhatsApp, though this behavior may vary by platform.

Parameters

Name	Type	Required	Description
jid	string	Yes	The JID of the contact to create or update (e.g., [email protected]).
fullName	string	No	The full name to assign to the contact.
saveOnPrimaryAddressbook	boolean	No	If set to true, it attempts to save the contact on the device's primary address book. Defaults to false.
