Get Started
Before you start, ensure you have:
Setting up an event in Calendly
Before we begin the Calendly WhatsApp integration, we need to create an event in Calendly. This is an important part of the integration, as we need to modify the default event by adding a question in the scheduling process asking invitees to provide their WhatsApp numbers. We will use that number to automatically send them a message when they schedule a meeting.
- Go to your dashboard in Calendly and click Create.
- Select Event type.
- Pick one of the options for event type.
- Click Next.
- Name your event.
- Select a location for your event.
- Click Next.
- Edit the availability options if necessary and click Next.
- Add an additional option → Invitee Questions.
- Type your question.
- In Answer type, select One line.
- Mark Required.
- Click Apply.
- Click Save and Close.
Once you’re done setting up your event, you can add the Calendly link in your marketing materials, inviting users to schedule a meeting with you.
Important: If no meetings are scheduled yet, schedule one yourself and then proceed with the integration. This is important because if you skip this step, you won’t be able to finish the integration.
