Help Integrations

WhatsApp

42min doesn't integrate with the WhatsApp API, so there's nothing to "connect". Instead, you reach WhatsApp the simple way: a routing form with a rule whose destination is an external URL pointing at a wa.me link. People who match that rule are forwarded straight into a WhatsApp chat with you.

What it is

  • A WhatsApp click-to-chat link looks like https://wa.me/<your-number> (digits only, with country code), optionally with ?text=<prefilled%20message>.
  • In a routing form, you point a rule at that URL via the external URL destination type, with no API keys and no setup beyond having the link.
  • This is the documented pattern for WhatsApp in 42min; there is no first-party WhatsApp messaging.

When to use it

  • Some leads should chat, not book a calendar slot: e.g. quick pre-sales questions, support, or markets where WhatsApp is the norm.
  • You want a "talk to us now" path alongside the "book a meeting" path on the same routing form.

How to do it

  1. Build (or open) a routing form at Routing Forms.
  2. Add a rule whose conditions match the people who should go to WhatsApp.
  3. Set that rule's destination to external URL and paste your wa.me link (e.g. https://wa.me/15551234567?text=Hi%2C%20I%27d%20like%20to%20chat%20with%20Acme).
  4. Keep a sensible fallback for everyone else (often an event type booking page).

Common pitfalls

  • Wrong number format. wa.me needs the full international number with no +, spaces, or dashes; just digits.
  • Prefilled text not URL-encoded. The ?text= value must be percent-encoded; spaces become %20, etc.
  • No fallback. A routing form still needs its mandatory fallback rule, since WhatsApp is one path, not the catch-all.
