# WhatsApp

Receive approval notifications at your confirmed WhatsApp number.

WhatsApp notifications send a request summary and review link to your confirmed WhatsApp number. WhatsApp is a separate channel from [SMS](/docs/web-app/sms-notifications), even when both use the same number. WhatsApp is a hosted edition channel: the open edition offers email, Slack and Discord.

## Number confirmation

The number needs consent to receive messages and confirmation from WhatsApp. withHuman provides a QR code and an **Open WhatsApp** link with a prepared confirmation message. Sending that message from your account confirms the number; opening the link alone does not.

If the confirmation expires, a new link replaces it. Once confirmed, the number becomes available in your [notification rules](/docs/web-app/notifications#standard-requests-and-interrupts). Add it to the urgency rules that should use it; confirmation alone does not turn on approval messages.

## Messages and availability

Approval messages show the tool, agent and expiry, with a link to the request. Request arguments stay in withHuman. Approval and denial happen in the [Review queue](/docs/web-app/review-queue), not in replies to the message.

WhatsApp delivery must be enabled on the deployment. Approval messages share the organization's phone-message allowance with SMS. When that allowance is unavailable or exhausted, the WhatsApp message is skipped and later notification rules continue.

## Delivery and removal

If a message is missing, check that the number is confirmed, its rule matches the request's urgency and the organization can send phone notifications. Include another channel in your rules as a fallback.

Removing the number also removes its WhatsApp rules. See [Changes and removal](/docs/web-app/notifications#changes-and-removal) for the effect on pending requests.
