Introduction

Maven is payment infrastructure for AI applications. Collect credit card payments securely over voice calls or inside a chatbot, using any major payment gateway.

Voice Payments

Collect card details via natural speech over phone calls.

Chat Payments

Embed a secure card form inside your chatbot or web app.

Any Gateway

Stripe, Authorize.net, Braintree, Shift4, or Fiserv — same API.

Two ways to collect

Voice
Chat / Web

Create a session

Your server calls the Maven API with the customer’s phone number, amount, and payment mode.

Transfer the caller

Your voice AI agent transfers the caller to Maven’s secure payment line.

Card details collected

Maven’s voice agent guides the caller through reading their card number, expiry, and CVV.

Payment processed

Card details are tokenized through VGS and the payment is processed through your gateway.

Get the result

Receive a webhook with the payment status and gateway details.

Create a session

Your server calls POST /v1/widget-sessions with the amount and gateway.

Mount the widget

Maven.createPayment({ sessionId }).mount("#slot") — the card form appears inline.

Customer pays

Card data goes browser → Maven iframe → VGS → gateway. Your page never touches it.

Callbacks fire

onSuccess({ transaction_id, card_brand, card_last4 }) on your page, plus a webhook to your server.

Security

Your server never touches card data in either flow — Maven handles tokenization and the gateway call. See Chat Widget Overview or Voice Overview for the full data-flow diagram.
