VantegrateNative API integrationIntegrate Aircall with AI agentsand connect the call with WhatsApp
Aircall is your sales and support team's cloud phone system. Vantegrate's AI agents connect through its REST API and real-time webhooks: when a call ends with its transcript, the agent follows up on WhatsApp with the context already in hand, and when the lead asks to talk, it hands off to a call without losing the thread.
How the data flows
What does it mean to integrate Aircall with Vantegrate's AI agents?
Integrating Aircall with Vantegrate's AI agents means connecting your cloud phone system to the WhatsApp channel through Aircall's REST API and webhooks. When a call ends, its event and its transcript trigger the agent to follow up on WhatsApp with context; and when the lead asks to talk, the agent hands off to a call or alerts the sales rep. Voice and chat stay in the same thread, synced in real time.
That is different from having the phone on one side and the chat on the other. Here the WhatsApp conversation starts already knowing what was said on the call, and every interaction is tagged and logged in Aircall and in your CRM. Aircall provides the phone system and the transcription; the agent's logic and the CRM live outside it and connect through the API. It's not a CRM or a bot builder: it's the voice channel of the flow.

What data moves between Vantegrate and Aircall
The agent works against the Aircall REST API and listens to its real-time webhooks: what happens on the call feeds the WhatsApp conversation, and what happens in the chat is logged in Aircall.
Call events and transcription
Aircall's webhooks report when a call ends (call.ended) and, through Conversation Intelligence, deliver its summary, sentiment and topics; that event triggers the WhatsApp follow-up with context.
Contacts, tags and comments
The agent matches the WhatsApp phone number against Aircall's Contact object to know whether the person is already a customer, see their call history and leave tags and comments on the record.
Messages and handoff to voice
Every WhatsApp conversation is logged as activity in Aircall; and when the lead asks to talk, the agent triggers an outbound call or alerts the sales rep without losing the thread.
How the integration works, step by step
Vantegrate handles the setup against the Aircall API. Your team validates, approves and starts using it.
Access to your account
We connect to your Aircall account through its REST API, using Basic Auth (api_id and api_token) or OAuth depending on your case, with the permissions you define.
Listening to webhooks
We subscribe a secure URL to the events that matter (call.ended, messages, contacts), so the agent reacts in real time as soon as something happens.
Mapping to your workflow
We define what triggers a WhatsApp follow-up, what hands off to a call and where each interaction is logged, in line with your CRM.
Validation with real data
We test with real calls and conversations, validate with your sales and IT teams, and roll out in phases.
From the call to WhatsApp without starting over
The classic problem is the break between channels: the customer calls, something is left pending, and when they pick it up again on WhatsApp they have to explain everything all over again. With the integration, Aircall's call.ended webhook marks the end of the call and its Conversation Intelligence delivers the transcript and the summary, which gives the agent the context to start the chat already knowing what was discussed.
It works the other way around too: if the WhatsApp conversation needs a human voice, the agent triggers a call or alerts the sales rep with the full history in view. Voice and chat stop being two separate systems and become a single journey, logged in Aircall and in your CRM.
| Dimension | Separate phone and chat | Integration with Vantegrate |
|---|---|---|
| Context | The customer repeats everything when switching channels | The call transcript feeds the WhatsApp chat |
| Trigger | Manual, it depends on someone remembering | Automatic by webhook (call.ended) |
| Handoff to voice | Passing the details to the sales rep by hand | A call triggered through the API, with the history |
| Record | Voice in one place, chat in another | Unified activity and tags in Aircall and the CRM |
| Identity | No way to know if they're already a customer | Phone number matched against the Aircall Contact |
Comparison of work patterns; the exact implementation is defined with your team based on your Aircall account and your plan.
The transcript and the analysis come from Aircall: its Conversation Intelligence generates the summary, the sentiment and the topics, and it depends on your plan. Vantegrate consumes that data through the API to give the agent context; it doesn't replace your phone system or your CRM, it connects them.

An agent connected to your Aircall vs. a standalone tool
| Standalone AI tool | Agent connected to your Aircall | |
|---|---|---|
| Data source | A copy that drifts | Your source of truth, live |
| Where your data lives | In a third-party system | In your environment, encrypted end to end |
| Result of each operation | Stuck in another app | Written back to your Aircall |
| Permissions and audit | Broad and hard to audit | Least-privilege scope and an audit trail |
| Reaching production | Often stalls as a pilot | Validated, phased rollout |

Which agent runs on your Aircall
The sales agent on WhatsApp uses Aircall as its voice layer: it listens to its events, reads the context of the call and logs the outcome.
The integration doesn't take your phone system anywhere else
The principle is simple: AI comes to your data, not your data to the AI. The agent works against your Aircall account through its official API, with the permissions you define and a log of every operation.
- Connection through the official Aircall REST API, with Basic Auth or OAuth, with no fragile bridges and no extra credentials.
- Only the permissions needed: the agent accesses what the use case requires and nothing more.
- Every interaction is logged and tagged in Aircall and synced to your CRM, with full traceability.
- Vantegrate enables and configures the integration; you operate your own Aircall account and your own CRM.
Frequently asked questions about the Aircall integration
What sales and IT teams usually ask before connecting an AI agent to their cloud phone system.
How do I integrate Aircall with an AI agent?
How do I integrate Aircall with an AI agent?
With the Aircall REST API and its real-time webhooks. The agent listens to events such as the end of a call (call.ended), reads its transcript and summary, and triggers a WhatsApp follow-up with context; it can also look up contacts, leave tags and trigger outbound calls. Vantegrate handles the setup; your team validates and approves it.
Is the WhatsApp integration included in Aircall?
Is the WhatsApp integration included in Aircall?
In Aircall, WhatsApp is a paid add-on and isn't included in every plan; Meta's messaging rates are also billed separately. Vantegrate's integration can use Aircall's WhatsApp or the WhatsApp Business API directly as the agent's channel. It's worth confirming your Aircall plan before you define the flow.
Does Aircall replace my CRM or my phone system?
Does Aircall replace my CRM or my phone system?
No. Aircall is your cloud phone system (voice, SMS and WhatsApp), and it provides call transcription and analysis through its Conversation Intelligence, depending on your plan. The AI agent's logic and your CRM live outside it and connect through the API: the integration joins those pieces, it doesn't replace them.
How does the context of a call carry over to the WhatsApp conversation?
How does the context of a call carry over to the WhatsApp conversation?
When a call ends, Aircall's call.ended webhook reports it, and the Conversation Intelligence webhooks deliver the summary, the sentiment and the topics of the conversation. Those events trigger the agent, which starts the WhatsApp chat already knowing what was said on the call, instead of starting from scratch. The transcription and the analysis are Aircall features and depend on the plan you have.
