CallSphere + Square
Process payments and manage transactions with CallSphere AI agents and Square. Handle phone payments, refunds, invoice lookups, and subscription management with PCI-compliant security. Whether a customer is calling to pay an outstanding invoice, check a transaction, or request a refund, the AI agent pulls live data from Square and completes the action in real time -- no hold music, no transfers, no manual processing.
Phone, in-store, and online payments all flow through Square's PCI DSS Level 1 infrastructure for one consistent ledger.
How does CallSphere integrate with Square?
CallSphere connects to Square through OAuth, scoped only to payments, invoices, and subscriptions. On a billing call the AI agent searches Square invoices and transaction history to answer questions, then captures card details via PCI-compliant DTMF or a Square payment link so sensitive data is processed through Square's certified infrastructure rather than CallSphere's. Refunds are matched to the original transaction and issued with a full audit trail, and subscription changes sync to Square immediately -- giving customers the same payment experience as your in-store and online channels.
How to connect Square
Get up and running in four simple steps. Most teams go live in under 30 minutes.
Connect Square Account
Authorize CallSphere via Square's OAuth flow. We request only the permissions needed for payments, invoices, and subscriptions -- nothing more.
Configure Payment Rules
Set refund limits, payment thresholds requiring manager approval, accepted payment methods, and subscription modification policies that align with your business rules.
Enable Secure Capture
Activate PCI-compliant DTMF tone capture or tokenized card entry so sensitive payment data is processed through Square's secure infrastructure and never stored on CallSphere servers.
Go Live
Process a test payment to confirm the integration is working, then activate. Your AI agent starts handling payment calls immediately, 24 hours a day.
What the Square integration enables
Payment Processing
AI agents securely collect payment details over the phone and process charges through Square's PCI-compliant infrastructure. Payments are confirmed to the caller in real time with a receipt sent via SMS or email.
Refund Management
Handle refund requests end-to-end during the call. The AI agent locates the original transaction in Square, verifies the amount and refund eligibility, and initiates the refund instantly with full audit trail.
Invoice Lookup
Customers calling about an invoice get immediate answers. The AI agent searches Square invoices by customer name, email, or invoice number and reads back the amount, due date, and payment status.
Subscription Management
Manage recurring billing over the phone. Customers can upgrade, downgrade, pause, or cancel Square subscriptions through a conversation with the AI agent, with changes reflected immediately.
Payment Link Delivery
For transactions that require the customer to enter their own card details, the AI agent generates a Square payment link and delivers it via SMS so the customer can complete the payment securely on their device.
Transaction History
Callers can ask about past payments, view recent charges, and get details on specific transactions. The AI agent pulls transaction history from Square and provides clear, itemized answers.
