This endpoint is for merchant-initiated termination only. ## OpenAPI ````yaml /openapi.json post /v0/subscriptions/{id}/termination openapi: 3.1.0 info: title: Paygentic API version: 0.1.0 description: > The Paygentic API provides a comprehensive platform for building and scaling monetization infrastructure. ## Authentication All API requests require authentication using an API key passed in the `Authorization` header: ``` Authorization: Bearer YOUR_API_KEY ``` ## Base URL All API requests should be made to: ``` https://api.paygentic.io/v0 ``` contact: name: Paygentic Support email: support@paygentic.io license: name: Proprietary servers: - url: https://api.paygentic.io description: Production API - url: https://api.sandbox.paygentic.io description: Sandbox API security: - BearerAuth: [] tags: - name: Customers description: >- A `Customer` is an entity connected to a `Merchant` via a `Subscription`. This represents the merchant-facing perspective of `Consumers` who purchase their `Products`. - name: Billable Metrics description: >- A `Billable Metric` defines a measurable quantity tied to a `Product`'s consumption. Each metric stores details including its label, an explanatory description, and measurement units. - name: Grants description: >- Grants credit a customer's metered entitlement balance. Merchants can create grants directly or void existing ones. Use `GET /v1/entitlements?customerId={id}` or `GET /v1/entitlements?subscriptionId={id}` to find the metered entitlement `id` needed for these endpoints. - name: Features description: >- A `Feature` represents a specific capability or functionality provided by a `Product`. Features can be metered (usage-based), static (fixed allocation), or boolean (enabled/disabled). - name: Fees description: >- A `Fee` defines a recurring or one-time charge tied to a `Product`. Fees are linked to prices, and cadence is defined on the Price. - name: Plans description: >- A `Plan` links a collection of `Prices` to a `Product`. It functions as a pricing structure document for a particular feature set or service offering. - name: Prices description: >- A `Price` determines the monetary value for a single unit of a `Billable Metric`. Prices are exclusively grouped within a `Plan`. - name: Products description: >- A `Product` is an offering sold by a `Merchant`. It includes product metadata like title, summary, and pricing details. `Plans`, `Prices`, and `Subscriptions` are all associated with products. - name: Sources description: >- A `Source` is an external data provider capable of automatically creating usage events. Configuration occurs at the plan level, enabling data retrieval from third-party platforms such as Stripe to produce billable events. - name: Subscriptions description: >- A `Subscription` is a customer's commitment to purchase a `Product` following the terms of a `Plan` and its linked `Prices`. - name: Users description: >- A `User` is an entity granted access to an Organization's resources. All operations are performed by users. - name: Invoices V2 description: >- Invoice V2 operations supporting billing cycles organized by time periods. Warning: v0 invoice endpoints are no longer supported. - name: Revenue description: Revenue data from invoices and payments - name: Profitability description: Per-customer profitability summaries - name: Test Clocks description: >- Test clocks provide programmable time control to simulate subscription and billing scenarios during testing. - name: Events description: Ingest raw metering events that are processed by the meters service. - name: Payments description: >- Create and manage one-off payments. A payment represents a single charge that a merchant wants to collect from a customer. - name: Payment Sessions description: >- Handle payment session lifecycle and processing across various entity types including invoices and subscriptions - name: Costs description: >- A Cost represents the operational or infrastructure expense of serving customers for a given product. Costs are metered (driven by event-based usage) and are tracked in parallel with billable metrics to give merchants visibility into both revenue and cost per customer. - name: ExternalReferences description: >- An `ExternalReference` links a Paygentic entity (e.g. an `Item`) to a record in an external system such as Salesforce or NetSuite. Multiple external records may map to the same Paygentic entity, but each external id is the *primary* reference of at most one entity per merchant. - name: Items description: >- An `Item` is the canonical "thing you sell" that external-system mappings point at. It is fully decoupled from the billing `Product` and holds no pricing/plan/metering, and it is CRM/ERP agnostic — which providers map to it lives entirely in its `ExternalReference` rows. - name: MerchantIntegrations description: >- A `MerchantIntegration` records a merchant's connection to an external provider. One connection per `(merchant, provider)` — re-connecting upserts in place. - name: Approvals description: Submit, decide, cancel, and read maker-checker approvals. - name: Orders description: Manage Orders, their line items, and billing schedules. - name: Billing Schedules description: >- Owner-polymorphic billing schedules with intervals and staged invoice projections. A BillingSchedule belongs to exactly one Order or one Subscription (XOR). Cadence lives on ScheduleIntervals (cadence-on-the-line). paths: /v0/subscriptions/{id}/termination: post: tags: - Subscriptions summary: Terminate description: >- Terminates a subscription with a required reason.
