How do I send an SMS or MMS via Twilio?

Short answer: You can send sms in Twilio by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Twilio Send SMS action to a workflow, map its 4 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

FAQ

Questions about Send SMS.

What does the Send SMS action do in Twilio?

Sends an SMS (or MMS, by adding MediaUrl) via Twilio to the destination number. US/Canada destinations require 10DLC or short-code registration to avoid carrier filtering.

What inputs does Send SMS require?

Required: To Phone Number, From Phone Number, Message Body. Every input accepts a static value or a variable from any upstream node in your workflow.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if Twilio returns an error?

The run history shows the failed step with its input and the error message Twilio returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.

Does Send SMS support batch operations?

Run Send SMS inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within Twilio's rate limits.
