Send Automated WhatsApp Link Calls For Your Business Meetings

WhatsApp call links remove the pressure of joining a call when you’re busy. Instead, your customers or partners can join a few moments later when they’re free.

With everyone being so busy on any given day, it’s not easy to get someone to answer a WhatsApp call — not to mention group calls. In the past, if you weren’t able to join a call on time, you had to call someone back, wait for the person to call you back, or align on a suitable time.

But it’s now easier to do that. WhatsApp has rolled out call links, which allow users to join an ongoing call. Here’s all you need to know about creating a call link on WhatsApp with Wassenger.

FAQs

1. How do I create a WhatsApp meeting link, and what is its purpose?

You can create a new WhatsApp meeting link for voice or video calls using the Meeting Links feature. This lets you start a call with any WhatsApp user by simply sharing a URL link. Optionally, you can add a description to remind you of the call’s purpose and set an expiration time for the link.

2. When does a WhatsApp meeting link expire?

By default, a meeting link will expire in 15 days if it’s not used. Once the link is used for a call, it will expire automatically. If the session is offline, the link cannot be created, and an error (503 Not Available) will be returned.

3. Can I delete or revoke a WhatsApp meeting link?

You can delete meeting links internally using their ID, URL, token, or creation date. However, once shared, the link cannot be revoked on WhatsApp. Others can still use the link if it has not expired.
