description: Gupshup is a conversational messaging and CPaaS platform (headquartered in India) that lets businesses send and
  receive messages across WhatsApp, SMS, RCS, and other channels, plus build chatbots and conversational AI journeys. The
  developer platform exposes REST APIs on api.gupshup.io - most prominently the WhatsApp Business API (send session and template
  messages, opt-in management, templates, media, and inbound webhooks) - authenticated with an apikey header and scoped to
  a registered app. Separate SMS, RCS, and Partner API surfaces are also documented.
