Airtable terminology

Extension - Extensions are modular components that add visuals or functionality to a base, and were shown in the base's dashboard. Users can create custom extensions, or they can use extensions created by Airtable or other open-source extensions.

Configure the extension settings

Once you do this, you can configure the extension settings. First, pick a table containing the phone numbers of the people to whom you'd like to send your messages; next, pick the specific phone number field containing the phone numbers. Lastly, you'll need to pick a view within the selected table—messages will only be sent to records visible in that view.

When writing your message, you can add values from the fields associated with each recipient by surrounding field names in curly brackets. You can use this to send each recipient a personalized message containing their own name, a date specific to an appointment they have, or other personalized data.
