Operation stripe.postplans

Provider route: POST /v1/plans. Alter supplies the connection’s credentials and routing.

Call through Alter

Install @alter-ai/sdk @alter-ai/stripe with npm, or alter-sdk-stripe with pip. Supply your connected customer’s grant ID and the arguments described below.

import { App } from "@alter-ai/sdk";

Create a plan — response body

Field	Type	Presence	Description and constraints
$	object	Root	You can now model subscriptions more flexibly using the [Prices API](https://docs.stripe.com/api#prices). It replaces the Plans API and is backwards compatible to simplify your migration. Plans define the base price, currency, and billing cycle for recurring purchases of products. [Products](https://docs.stripe.com/api#products) help you track inventory or provisioning, and plans help you track pricing. Different physical goods or levels of service should be represented by products, and pricing options should be represented by plans. This approach lets you change prices without having to change your provisioning scheme. For example, you might have a single "gold" product that has plans for $10/month, $100/year, €9/month, and €90/year. Related guides: [Set up a subscription](https://docs.stripe.com/billing/subscriptions/set-up-subscription) and more about [products and prices](https://docs.stripe.com/products-prices/overview).

Policy, approvals and errors

SDK function policy ID: stripe.postplans. Catalog operation: PostPlans. Rules can name either ID; function rules distinguish managed calls and conservatively cover raw calls sharing the route. Existing grant permissions and policy rules apply. wait() returns an immediate result or waits for a required approval; it never approves the request itself. Persist the approval ID to resume after a restart.

Provider errors retain their response; JSON decoding raises ProviderAPIError for provider failures. ManagedOperationError identifies contract/input/retention errors. See error handling and provider-specific behavior. Sensitive input may be refused before approval storage. A decoding error never resubmits a write.
