# Overview

Task-shaped walkthroughs that compose multiple endpoints. If you know what you want to accomplish, start here.

* [Onboard a subscriber](/guides/onboard-a-subscriber.md) — create → subscribe → activate, including an inline OpenAPI block
* [Handle a plan change](/guides/handle-a-plan-change.md) — upgrade or downgrade an active subscription
* [Reconcile a payment](/guides/reconcile-a-payment.md) — match a SasaPay payout to a Share payment
* [One-time charges](/guides/one-time-charges.md) — bill a subscriber outside the normal cycle
