What is Make used for in a Bolna voice agent?

Make connects Bolna to other apps in visual scenarios: it can place outbound calls through your agent, and it can start a scenario with the full call data every time a call ends. Pick it when you want post-call follow-ups or CRM updates without running your own webhook server.

How do I set up Make with Bolna?

  1. For actions, add the Make an outgoing phone call module to your scenario and create a Bolna API connection with an API key from Developers → API Keys in the Bolna dashboard.
  2. For post-call automations, add the Watch end of phone call trigger, create a webhook connection, give it a name and copy the webhook URL Make generates.
  3. Paste that URL into the Webhook URL field on your agent's Extractions tab and save the agent.
  4. Add your next modules (Gmail, Twilio, WhatsApp or any other app), map fields from the call payload, then run the scenario with a test call.

Which modules does Bolna support on Make?

ModuleTypeWhat it doesConnection
Make an outgoing phone callActionPlaces an outgoing call from your Bolna agent to a phone numberBolna API connection
Make an API callActionCalls any authorized Bolna API endpointBolna API connection
Watch end of phone callTriggerReceives the full call payload after each callBolna webhook connection

Useful fields in the trigger payload: extracted_data for your extractions, context_details.recipient_data for the variables you passed when making the call, and summary when Call Summary is on.

What can you automate with Make and Bolna?

Email after every call. Send the caller or your team an email with details pulled from extracted_data. The docs example uses Gmail.

SMS follow-ups. Text the caller a short summary or next step after the call. The docs example uses Twilio, and any SMS module works.

WhatsApp follow-ups. Send a WhatsApp message once the call ends, using recipient data such as the caller's name. If you only need WhatsApp templates inside a Bolna workflow, AiSensy does that without Make.

Calls from other apps. Use Make an outgoing phone call to dial a lead when a new record appears in your CRM, sheet or form tool.

Multi-step updates. Branch on the call payload and update several systems in one scenario, for example a CRM record and a team notification.

FAQ

Make (formerly Integromat) on Bolna: frequently asked questions

There are two action modules, Make an outgoing phone call and Make an API call, and one trigger, Watch end of phone call. Actions use a Bolna API connection; the trigger uses a webhook connection.

The Watch end of phone call trigger gives you a webhook URL. Paste it into your agent's webhook URL field and save the agent, and Make receives the full call payload after every call.

Yes. Extractions arrive under extracted_data, and the variables you passed when making the call arrive under context_details.recipient_data. The summary field is filled only if you turn on the agent's Call Summary toggle.

Yes. The Bolna docs walk through a scenario that uses the Watch end of phone call trigger with a Whatsable module. Any WhatsApp, email or SMS module on Make works the same way.

Tools & Workflows

Tools let your voice agents take action during a call, not just talk. Book a calendar slot, look up an order through your own API, push a lead into your CRM, or trigger a multi-step automation in Zapier. These integrations turn voice agents from answering machines into workflow engines.

Browse

Telephony

Telephony providers connect your voice agents to the phone network so they can make and receive real calls. Bolna supports managed integrations with major carriers as well as bring-your-own-carrier via SIP trunking, giving you full control over call routing, number provisioning, and cost.

Large Language Models

The LLM is the brain of your voice agent. It understands what callers say and decides how to respond. Bolna lets you switch between models like GPT-5.4 mini, Claude and DeepSeek by changing the provider and model in your agent LLM settings, so you can tune for speed, cost or reasoning depth.

Browse

Speech-to-Text

Speech-to-text converts what callers say into text that your LLM can process. Transcription accuracy and latency directly affect how natural a conversation feels. Bolna supports streaming STT providers optimized for telephony audio, including specialized models for Indian languages.

Text-to-Speech

Text-to-speech turns your agent responses into spoken audio. Voice quality shapes how callers perceive your brand. Flat, robotic speech kills trust while natural, expressive voices build it. Bolna integrates with the fastest TTS providers so responses sound human and arrive without awkward pauses.
