Slack: Team chat app where small teams talk in channels and direct messages instead of email.

Connects

Example call

A caller says their walk-in freezer stopped working. The receptionist takes an urgent message, and the owner's #urgent channel in Slack shows the caller's name, number and a short summary of the problem.

Post every finished call to a #calls channel with the caller's name, number, summary and recording link, using Zapier's Send Channel Message action, Make or n8n.
Filter message.taken events on urgency in Zapier or Make so urgent messages go to an on-call channel or a manager's direct messages.
During a live call, post an alert to a chosen channel with chat.postMessage and the business's own bot token, so the team sees it while the caller is still on the line.

How it connects

Zapier: Send AssistCall events to a Zap (Webhooks by Zapier, Catch Hook), then use the app's Zapier actions. Needs a paid Zapier plan.
Make: Start a Make scenario with a custom webhook and use the app's Make modules.
n8n: Start an n8n workflow with a webhook node, then call the app with its node or an HTTP request.
Live API actions: During the call, the receptionist calls the app's API with your key to look up or create records.
Call forwarding: Forward your business line to AssistCall when busy, after hours or always. Works with any carrier.

About Slack's API

Self-serve API: you can create a key in your account
Style: REST-style Web API, plus Events API
Authentication: OAuth 2.0 bot token (xoxb) from the business's own Slack app; incoming webhook URLs
On Zapier: yes. On Make: yes.

Any workspace can create its own Slack app and bot token; depending on workspace settings, installing it may need admin approval. The bot needs the chat:write scope and must be added to the channel it posts to. Incoming webhooks require a 'text' field, so AssistCall's raw JSON events can't post straight to a Slack webhook. Zapier, Make or n8n turns them into a message. chat.postMessage allows about one message per second per channel.

Not included: no one-click Slack app, no listing in Slack's marketplace, no two-way sync, and no partnership with Slack Technologies (a Salesforce company).
