Frequently asked questions

Sim's Twilio SMS integration adds 2 real-time triggers to the AI agents you build in Sim's visual workflow builder — no code required. Send SMS messages. Teams often pair Twilio SMS with AgentPhone and Discord in the same agent.

Connecting Twilio SMS takes about five minutes: (1) Create a free account at sim.ai. (2) Create an agent in your workspace. (3) Drag a Twilio SMS block onto the workflow builder. (4) Paste your Twilio SMS API key to authenticate — you can find it in your Twilio SMS account settings. (5) Choose the Twilio SMS event you want to listen for, and your agent runs automatically from then on.

Add a Twilio SMS trigger block to your agent and copy its generated webhook URL into Twilio SMS's webhook settings. Sim supports 2 real-time triggers for Twilio SMS: Twilio SMS Received and Twilio Message Status. Once configured, every matching Twilio SMS event starts your agent instantly — no polling, no delay.

Sim receives the full event payload Twilio SMS sends — typically the record or object that changed, plus metadata like the event type and timestamp. For example, the "Twilio SMS Received" trigger fires when an inbound SMS or MMS message is received via Twilio. Every field in the payload is available as a variable you can pass to AI blocks, conditions, or other integrations.
