Initiate an outbound SMS

Zoom SMS handler for initiating outbound SMS

Zoom SMS Handler seamlessly initiates outbound SMS messages from third-party applications directly in the Zoom client.

A dedicated handler URI scheme makes it easy to pre-fill phone numbers from external apps in Zoom to initiate SMS communications.

Handler URI scheme

zoomphonesms://{recipient_nr}?callerid={from_nr}

Initiate outbound SMS messages

Zoom provides support for various URI schemes that empowers you to send SMS messages from the Zoom client directly from your applications.

Prerequisites

Before using these schemes, ensure the following prerequisites:

• Installation of the latest version of the Zoom client with an active session. (Zoom client 6.1.0 and above for both desktop and mobile clients)
• Possession of a valid Zoom Phone number that enables you to send and receive SMS.

Supported URI schemes

Zoom extends support for the following URI scheme to seamlessly launch the Zoom client and send SMS messages: zoomphonesms://{recipient_nr}?callerid={from_nr}

Implement the SMS scheme

Recipient number

The recipient's phone number follows immediately after the scheme component, indicated by a colon (:) and two slashes (//).

This parameter is mandatory and specifies the recipient who will receive the message.

CallerID parameter

The callerid parameter allows users to specify the desired caller ID for the outbound SMS message. For example zoomphonesms://+123456789?callerid=+16692520210 initiates an SMS message with the specified callerid +16692520210.

Note that the callerid must adhere to Zoom's format requirements. If the caller ID is invalid, we ignore the parameter.

Streamlined SMS messaging

The Zoom SMS Handler simplifies outbound SMS messaging. As a result, you can prefill phone numbers from third-party apps into Zoom with the designated handler URI scheme.
