Twilio is an API for sending text messages and making calls.
Connecting Retool to Twilio takes just a few minutes, and lets you to send texts or make calls programatically from Retool. For example, you could build a tool to send personalized texts to inform users of last minute changes in plans. You could pull your
users from a Postgres database, drag on a
TextInput to write a personalized text message, and then drag on a
Button to actually send the text via Twilio. You can also use Retool to build a UI to track the confirmations.
