Hello, I still am not seeing how to easily integrate Slack/Calendly and other apps into AI Assistants. Is there a clear guide?

To integrate Slack with your Vapi AI Assistant, follow these steps: 1. In the Vapi Dashboard, go to Providers Keys > Tools Provider > Slack and connect your Slack workspace. 2. Create a Slack tool, specifying the target channel in the description (e.g.,

#customer-support

). 3. Add the tool to your assistant under the Functions tab. Example configuration:

json
{
  "type": "slack.message.send",
  "name": "notifySupport",
  "description": "Send urgent notifications to the #customer-support channel when a customer needs immediate attention."
}

For more details, see the [Slack integration guide](https://docs.vapi.ai/tools/slack) in the documentation. Source: - [Slack Integration](https://docs.vapi.ai/tools/slack)

You should take a look at building Custom Tool backends using Make.com. Make gives you access to almost 3,000 SaaS solutions, including all the major (and many minor) CRMs, ERPs, Finance/Accounting systems, HR systems, Project Management tools and more.

is there documentation regarding make.com

Hi NickVapi, If you have any specific questions or require help with our features, feel free to ask. With recent updates, you can now utilize features such as making phone calls over WebSockets with

vapi.websocketCall

and simplify transport configurations in calls. Additionally, if you're exploring workflow enhancements, consider the new conversation tasks using the "Conversation" node. For full details on these updates, check the relevant sections [here](https://docs.vapi.ai/changelog/2025/4/8) and [here](https://docs.vapi.ai/changelog/2025/5/8).

@NickLLMVoice There are a lot of YouTube videos, but I'll admit the documentation on using the Vapi app in Make hasn't been great up to this point. We're releasing a new version of the Vapi app in Make at VapiCon on Oct 2. One of the goals of the new version is to make it way easier to configure Custom Tools. There'll be a supporting post on the Make blog showing best practice in how to use this. If you can wait till then it will be easier - but if your need is urgent, check out the various YouTube vids for guides.
