# Checkout

> Accept payment and activate subscriptions in a hosted checkout flow, without building any payment UI.

Flexprice Checkout is a hosted payment integration that handles the full subscription activation sequence for you. Connect a payment provider, create a session from your backend, and redirect your customer. Flexprice takes care of the payment page, the subscription, the invoice, and the cleanup if something goes wrong.

It is the fastest way to go from a pricing page to an active, paying subscriber.

## When to use Checkout

Use Checkout when your customers initiate and pay for their own subscription: a self-serve pricing page, an upgrade flow, or a sign-up gate.

If you create subscriptions on behalf of customers from your own backend (after a sales call, from an admin dashboard, or via contract), use the [Subscriptions API](/docs/subscriptions/customers-create-subscription) instead.

## How it works

Your backend creates a Checkout Session with the customer, plan, and payment provider. Flexprice generates a hosted payment page URL and returns it to you. You redirect the customer there. Once payment is complete, Flexprice activates the subscription and finalizes the invoice.

If the customer cancels, the session times out, or the payment fails, Flexprice cleans up all draft records automatically.

## Choose your payment provider

Each provider has its own setup page with connection instructions, webhook configuration, and test credentials.
