Migrating to Prices

Learn how to update your integration to use prices for one-time purchases and recurring billing.

The Prices API adds more flexibility to how you charge customers. It also replaces the Plans API, so Stripe recommends migrating your existing integration to work with prices. To migrate, you need to identify how you use plans, products, and payment flows and then update these parts of your integration to use the Prices API.

Identify how you use plans, products, and payment flows

The Prices API impacts the Invoices, Subscriptions, and Checkout APIs. Stripe recommends updating your integration if you:

Bill your customers using invoice items and the create invoice API.
Bill customers with subscriptions.
Use subscription schedules to manage subscriptions for your customers.
Use Checkout with custom line_items, items with SKUs, or subscription_data[items] with plan IDs. See the Checkout migration guide to make sure you’re using the latest version of Checkout before working through the rest of this guide.

Review the differences between plan and price

The price object is similar to the plan object, but a few fields have been renamed and some fields are now optional. Below is a summary of the changes to the API for creating prices:

Plan	Price
`amount` optional	`unit_amount` optional
`amount_decimal` optional	`unit_amount_decimal` optional
`interval` required	`recurring[interval]` optional
`interval_count` required, defaults to 1	`recurring[interval_count]` optional
`trial_period_days` optional	`recurring[trial_period_days]` optional
`usage_type` optional	`recurring[usage_type]` optional
`aggregate_usage` optional	`recurring[aggregate_usage]` optional
`transform_usage` optional	`transform_quantity` optional

Invoices

If you manually create invoice items to bill your customers, replace unit_amount or amount with a price and quantity. For example, if you charge a 20 USD setup fee, you pass the unit_amount and quantity in every /v1/invoiceitems call. Instead, you create a product and a price, and then pass the price in /v1/invoiceitems calls instead.

Subscriptions

If you use subscriptions to bill your customers, you can continue to pass plan IDs into the Prices API. Plans are recurring prices, and can be updated and retrieved in the /v1/prices endpoints. You can also pass plan IDs into the various price fields. For example, if you have a plan with ID plan_abc:

: \
  -d customer=cus_GWZ4fLmuDlz4Ye \
  -d "items[0][price]"=plan_abc

If you previously implemented one-time fees on subscriptions by adding invoice items to a customer or subscription, you may continue to do so. You can also pass a price and quantity in add_invoice_items within the Subscriptions API. For example, if you previously included a setup fee when you created subscriptions, you had to create a pending invoice item and create the subscription. You can now do this in a single API call:

: \
  -d customer=cus_GWZ4fLmuDlz4Ye \
  -d "items[0][plan]"=plan_abc \
  -d "add_invoice_items[0][price]"=price_def

This subscription appends a 20 USD invoice item for the setup fee defined in price_def to the first invoice.

Subscription schedules

For subscription schedules, replace all references to plan with price, and pass add_invoice_items into phase configurations, similar to the migration for subscriptions above.
