Build agentic AI SaaS Billing workflows

Automate recurring Billing workflows using the Stripe API and AI-driven agents.

You can enable your AI agents to create and manage subscription-based SaaS Billing programs with Stripe. In this guide, you’ll learn how to:

Provision a new customer and subscription
Respond to subscription lifecycle events using webhooks
Invoke billing actions from an AI agent using the agent toolkit

Before you begin

This guide assumes you have a working agent toolkit setup and a Stripe account. You’ll link to these resources throughout:

Additionally, make sure that you have the following:

Node.js 14 or later and an existing agent toolkit project
A Stripe test account with API keys
Either the Stripe Agent Toolkit installed or Model Context Protocol (MCP) server configured to talk to your Stripe account

Provision customers and subscriptions

To provision customers and subscriptions, your agent needs to create a new customer and attach a subscription. Here’s an example using the Stripe Node.js SDK:

See Build subscriptions for pricing and trial options.

Handle billing events with webhooks

Subscriptions in your application trigger various events such as renewals, failed payments, and cancellations. Some billing events are asynchronous, and you need your agent to respond to them. For example, if a subscription cancels, have your agent follow up with the customer or make an offer to retain them.

To manage these events, use webhooks to listen for and respond to these triggers.

The code example below demonstrates how to set up an Express server that listens for Stripe webhook events, validates incoming requests, and handles specific event types such as successful payments, failed payments, and subscription cancellations. After you capture these events, call into an agent to react accordingly.

Manage billing using the agent toolkit

You can use the agent toolkit to enable AI agents to automatically initiate billing flows.

You can implement this directly in code or in an application such as Claude or an MCP server.

Here’s an example using Vercel’s AI SDK:

Here’s an example using Stripe’s MCP server with OpenAI’s Responses API:

Testing

You can test your integration using Sandboxes. This allows you to simulate payment processing and other features without affecting your live account or data.
