Connects

Example call

Caller says "Is my pickup order ready?" AssistCall finds the caller in Square Customers by phone, searches their recent orders and reads back the status; the owner gets the call summary by email.

• During a call, AssistCall searches your Square customer directory by the caller's phone number so the receptionist can greet returning customers by name.
• During a call, AssistCall searches that customer's recent Square orders with your personal access token and tells the caller the order's status.
• When AssistCall captures a lead, a Zap creates the caller as a Square customer with Create Customer.

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.
