Connect WhatsApp with Cal ID
Use WhatsApp as a meeting location so guests meet you over a WhatsApp chat or video call.
Cal ID lets you use WhatsApp as a meeting location for your event types. Install the WhatsApp app from the Apps section, add it as the location on any event type with your WhatsApp chat link, and every booking carries that URL so you and the guest can start the chat or video call straight from the booking details. It is a simple way to meet people where they already message, with no video link to join, and it works on every Cal ID plan, including the free plan.
Why connect WhatsApp
Meet where guests already are
Connect over a WhatsApp chat or video call instead of a separate video meeting link.
Added to every booking
The WhatsApp URL you set becomes the meeting location, visible to both the host and the booker in their booking details.
Set it per event type
Choose WhatsApp for each event type separately, and decide whether to show the location on your public booking page.
Free on every plan
Using WhatsApp as a meeting location is available on every Cal ID plan at no extra cost.

Common questions about connecting WhatsApp with Cal ID.
01 Is the WhatsApp integration free?
Yes. Using WhatsApp as a meeting location is available on every Cal ID plan, including the free plan, at no extra cost.
02 What does the WhatsApp integration do?
It lets you set WhatsApp as the meeting location for an event type. When someone books, your WhatsApp chat URL is added to the booking so you and the guest can start the chat or video call from the booking details.
03 Do I need a WhatsApp Business account?
No. You only need a WhatsApp chat link, a wa.me URL for the number you want guests to reach. The integration adds that link as the meeting location and does not send messages on your behalf.
04 Does it start the WhatsApp call automatically?
No. The WhatsApp URL is the meeting location, so the host or the guest opens WhatsApp and starts the chat or call from the booking details.
05 Can I use a different WhatsApp number for each event type?
Yes. WhatsApp is configured separately on each event type, so you can use different chat URLs for different meetings.
