Overview

This REST API lets you send WhatsApp messages — text, image, video, audio, document, and location — from a WhatsApp number connected via QR code in the OnlineLiveSupport CRM dashboard. No Meta Business API, template approval, or phone-number verification is required.

Base URL

https://crm.onlinelivesupport.com

Self-hosted / white-label instances use their own domain as the base URL.

Authentication

Every request is authenticated with your API Token, sent as token in the JSON request body.

Get your token: CRM Dashboard → Add WhatsApp by QR → Rest API tab → Copy API Token.
