Connects

Example call

A caller asks for a consultation while the owner is with a client. The receptionist takes their details and what they need. A Zap creates the contact in Capsule with a note and a callback task, and the owner sees the task in Capsule.

• After a call, a Zap finds or creates the caller as a Capsule contact and adds the AssistCall summary as a note.
• lead.captured events create an opportunity in your Capsule pipeline through Zapier.
• During a call, the receptionist uses your personal access token to search Capsule for the caller's details and greets existing contacts by name.

How it connects

• Webhook: Signed JSON for every call, message and booking, sent to any HTTPS URL you choose.
• Live API actions: During the call, the receptionist calls the app's API with your key to look up or create records.
• 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.
• Call forwarding: Forward your business line to AssistCall when busy, after hours or always. Works with any carrier.

About Capsule's API

• Self-serve API: you can create a key in your account
• Style: REST (v2)
• Authentication: Personal access token (Bearer) from My Preferences > API Authentication Tokens, or OAuth 2.0
• On Zapier: yes. On Make: yes.

Personal access tokens suit integrations for a single account, and OAuth is for apps other people use. REST hooks (subscribe and unsubscribe) let Capsule push changes so integrations don't have to poll. This research did not find published rate limits or plan limits on API access.

Not included: no one-click Capsule app, no listing in Capsule's marketplace, no two-way sync, and no partnership with Capsule.
