Subscriptions

Subscriptions renew a customer on a recurring price. Ching handles the first charge, the renewal cron, retries on failure, and document issuance.

Use cases: Build SaaS billing, offer yearly plans, or run memberships with free trials.

POST/v1/subscriptions

Create a subscription and charge the first period immediately (unless the price has a trial, in which case the first charge runs at trial end).

If the first charge fails in live mode, the response is 402 with error.code CHARGE_FAILED and no subscription is created.

Body Parameters

Name	Type		Description
`customer`	string	required	The customer id.
`payment_method`	string	required	Active payment method id to charge on each renewal.
`price`	string	required	A recurring price id. Determines amount and renewal cadence.
`metadata`	object		Set of key-value pairs you can attach to the object for your own use. Returned as-is on retrieval.
