Connects

Example call

A gym member calls asking what she still owes. The receptionist finds her in Stripe by phone number, sees one open invoice, and tells her $65 is due on the 1st. The owner gets the call summary by email.

• During a call, the receptionist searches your Stripe customers by the caller's phone number to confirm who is calling.
• The receptionist lists that customer's open Stripe invoices and tells the caller the amount still due and the due date.
• When AssistCall captures a new lead, a Zap uses Stripe's Find Customer action and then Create Customer if no match is found, adding the caller to Stripe.

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 Stripe's API

• Self-serve API: you can create a key in your account
• Style: REST (form-encoded requests, JSON responses)
• Authentication: Secret or restricted API key, sent as a Bearer token. Keys stay valid until you roll or delete them.
• On Zapier: yes. On Make: yes.

Create a restricted key in the Stripe Dashboard with read access to Customers and Invoices, and save it in AssistCall as 'Authorization: Bearer rk_live_...'. Stripe's v1 API takes form-encoded request bodies, not JSON, so AssistCall's live lookups should use GET requests. For customer search, use GET /v1/customers/search with query=phone:"+1...". It's an exact match, so the phone numbers stored in Stripe need to be in the same format as caller ID. For invoices, use GET /v1/invoices?customer=...&status=open, or search by invoice number. Stripe rejects parameters it doesn't recognize, so switch off AssistCall's automatic caller_phone and call_id fields for these calls. New or changed records usually show up in search within a minute. Search endpoints are limited to 20 reads per second, and search isn't available to businesses in India.
