Frequently asked questions

Sim's WhatsApp integration adds 6 WhatsApp tools and 1 real-time trigger to the AI agents you build in Sim's visual workflow builder — no code required. Send WhatsApp messages. Teams often pair WhatsApp with Telegram and Microsoft Teams in the same agent.

You can send Message, send Template, send Media, send Interactive, and send Reaction with WhatsApp in Sim, plus 1 more WhatsApp tools listed on this page. Each runs as a tool inside an AI agent block, so an agent can chain WhatsApp with services like Telegram and Microsoft Teams and apply LLM reasoning between steps.

Connecting WhatsApp takes about five minutes: (1) Create a free account at sim.ai. (2) Create an agent in your workspace. (3) Drag a WhatsApp block onto the workflow builder. (4) Paste your WhatsApp API key to authenticate — you can find it in your WhatsApp account settings. (5) Pick a tool such as "Send Message", wire up its inputs, and click Run — your agent is live.

Add a WhatsApp block to your agent and select "Send Message" as the tool. Send a text message through the WhatsApp Cloud API. Fill in the required fields — inputs can reference outputs from earlier steps, such as text generated by an AI block or data fetched from another integration. No code is required.

Add a WhatsApp trigger block to your agent and copy its generated webhook URL into WhatsApp's webhook settings. Sim supports 1 real-time trigger for WhatsApp: WhatsApp Webhook. Once configured, every matching WhatsApp event starts your agent instantly — no polling, no delay.

Sim receives the full event payload WhatsApp sends — typically the record or object that changed, plus metadata like the event type and timestamp. Every field in the payload is available as a variable you can pass to AI blocks, conditions, or other integrations.
