## Request Body

**Content type:** `application/json`

Schema: [`ContractPlanCreateDto`](https://devportal.demo.winkpg.io/docs/api/models/ContractPlanCreateDto.md)

Properties:
- `merchantId` (string(uuid)) required: The merchant that owns the plan. (nullable)
- `name` (string) required: The plan's operator-facing name. Must be unique within the owning merchant. (nullable, max length 128)
- `code` (string): The merchant's own short code for the plan. Optional, and not resolved by the platform. (nullable, max length 64)
- `description` (string): What the plan covers, in the operator's own words. (nullable, max length 1024)
- `currencyCode` (string) required: The ISO 4217 alphabetic currency code the plan's amounts are denominated in. (nullable, min length 3, max length 3, pattern ^[A-Za-z]{3}$)
- `isActive` (boolean): Whether the plan may be subscribed to. Turning it off hides it from the plan picker and  blocks new subscriptions; it does not stop billing the contracts already on it.
- `defaultSchedule` ([ContractSchedule](https://devportal.demo.winkpg.io/docs/api/models/ContractSchedule.md)): The recurrence a new contract on this plan starts from. Optional, and a suggestion only: the  contract owns its schedule once created.
  Fields:
  - `frequency` ([Frequency](https://devportal.demo.winkpg.io/docs/api/models/Frequency.md)): The type of the recurrence rule.
    Values:
    - `Secondly`
    - `Minutely`
    - `Hourly`
    - `Daily`
    - `Weekly`
    - `Monthly`
    - `Yearly`
  - `count` (integer(int32)): The number of occurrences in a particular recurrence. (nullable)
  - `until` (string(date-time)): The datetime that bounds the current recurrence. (nullable)
  - `interval` (integer(int32)): The recurrence interval.
  - `bySecond` (array<integer(int32)>): BySecond rule modifier. (nullable)
  - `byMinute` (array<integer(int32)>): BySecond rule modifier. (nullable)
  - `byHour` (array<integer(int32)>): BySecond rule modifier. (nullable)
  - `byDay` (array<[ContractScheduleByDayRule](https://devportal.demo.winkpg.io/docs/api/models/ContractScheduleByDayRule.md)>): Week day rule modifier. (nullable)
  - `byMonth` (array<integer(int32)>): Month day rule modifier. (nullable)
  - `byMonthDay` (array<integer(int32)>): Month days rule modifier. (nullable)
  - `byYearDay` (array<integer(int32)>): Year days rule modifier. (nullable)
  - `byWeekNumber` (array<integer(int32)>): Week number rule modifier. (nullable)
  - `bySetPosition` (array<integer(int32)>): BySetPosition rule modifier. (nullable)
  - `firstDayOfWeek` ([DayOfWeek](https://devportal.demo.winkpg.io/docs/api/models/DayOfWeek.md)): The first day of week, used in calculating weekday-based recurrences (nullable)
    Values:
    - `Sunday`
    - `Monday`
    - `Tuesday`
    - `Wednesday`
    - `Thursday`
    - `Friday`
    - `Saturday`
  - `nextScheduledRun` (string(date-time)): The next computed billing date, updated after each billing run. Null for contracts that  have never been scheduled or have ended. (nullable)
  - `startDate` (string(date-time)): The earliest date on which this contract is eligible to bill. Set by the user  when creating the contract (defaults to the creation date) and may be set to a  future date to delay first billing. The recurrence engine anchors expansion to  this date and the daily billing job will not fire a contract whose  `startDate` is in the future.                Null on contracts created before this field existed. When it is null, the server  anchors the schedule on the contract's creation time, or on the current time when  that is also absent; callers that compute a schedule themselves should apply the  same fallback. (nullable)
- `trialDays` (integer(int32)): The trial length a new contract on this plan inherits, in days. Optional; empty or zero  means no trial. A default for contract creation only: each contract owns its own trial end  date once created, and changing this never moves an existing subscriber. (nullable, min 0, max 365)
- `billSubtotalAmount` (number(double)): The base amount the plan charges each cycle, before tax. (min 0)
- `taxAmount` (number(double)): The tax added to the base amount each cycle. Leave empty when the plan carries no tax line. (nullable, min 0)
- `totalAmount` (number(double)): The total charged to a subscriber each cycle. This is the amount the billing engine charges;  the subtotal and tax are the operator's breakdown of it. (greater than 0)

_Example: Plan without a trial_

Adds a plan that charges subscribers 129.90 a month (120.00 plus 9.90 of tax). The opening price is in force from the moment the plan exists; change it later with POST /api/contract-plans/{id}/prices, which keeps every earlier price. The name must be unique within the merchant. The default schedule only seeds a new contract's recurrence, and each contract owns its schedule once created.

```json
{
  "billSubtotalAmount": 120,
  "taxAmount": 9.9,
  "totalAmount": 129.9,

  "currencyCode": "USD",
  "isActive": true,
  "defaultSchedule": {
    "frequency": "Monthly",
    "interval": 1
  }
}
```

_Example: Plan with a 14-day trial_

Adds a 49.00 monthly plan whose new subscribers start on a 14-day trial: a contract created on the plan with no trial end date of its own is not charged until the trial ends. The trial is a default for new contracts only, so changing it later never moves an existing subscriber.

```json

  "billSubtotalAmount": 49,
  "totalAmount": 49,

- `currentPrice` ([ContractPlanPriceDto](https://devportal.demo.winkpg.io/docs/api/models/ContractPlanPriceDto.md)): The plan's price today: the revision in force at the moment the plan was read, with no  scheduled run to measure a next-cycle change against.
  Fields:
  - `id` (string(uuid)): Identifies this revision.
  - `billSubtotalAmount` (number(double)): The base amount charged each cycle, before tax.

  - `taxAmount` (number(double)): The tax added to the base amount each cycle, or null when the plan carries no tax line. (nullable)
  - `totalAmount` (number(double)): The total charged to the subscriber's payment method each cycle.
  - `effectiveFrom` (string(date-time)): The moment this revision starts applying, in UTC.
  - `policy` ([ContractPlanPriceChangePolicy](https://devportal.demo.winkpg.io/docs/api/models/ContractPlanPriceChangePolicy.md)): The propagation policy the revision was saved under.
    Values:
    - `Immediate`: The new price applies to every charge executed from the moment the change was saved, including a charge that was already due and has not run yet.
    - `NextCycle`: The new price applies only to charges that fall due after the change was saved. A charge that was already due when the price changed still bills at the old price, so a subscriber is never re-priced part-way through a cycle they have already entered.
    - `Scheduled`: The new price applies to charges executed on or after an operator-chosen effective moment. Until then every subscriber keeps billing at the previous price.
  - `recordedAt` (string(date-time)): When the revision was saved, in UTC.
  - `recordedByUserId` (string(uuid)): The operator who saved the revision, or null when the platform wrote it. (nullable)
  - `note` (string): Why the price changed, in the operator's own words. (nullable)
- `concurrencyStamp` (string): The concurrency stamp used for optimistic concurrency control. (nullable)
- `entityVersion` (integer(int32)): The entity version, incremented on each modification.

_Example: Request failed validation_

One or more fields were rejected before any rule ran. error.code is null on the envelope and the causes are in validationErrors, one entry per failure. An entry carries code when the validator declared a publishable one, and memberPaths when the full path says more than members does (an element inside a collection, for example). Both keys are omitted when they would add nothing.

_Example: Resource not found_

The id in the path names no record the caller can see. Most resources answer with a null error.code and a message naming the resource type and the id; a resource that publishes a not-found code in the catalog above carries it in error.code instead, so check for one before matching on the message.

### default

The request failed. The body carries the standard error envelope: a machine-readable `error.code`, a human-readable `error.message`, and `error.validationErrors` when the failure was a validation rejection. The [error reference](https://devportal.demo.winkpg.io/docs/errors.md) lists the values `error.code` can take.

_Example: Business rule refused the request_

The request was understood and rejected by a platform rule. This is the shape that carries a code from the catalog above, so branch on error.code rather than on the message text. The HTTP status is the one listed against the code.

```json
{
  "error": {
    "code": "Transactions:OperationNotAllowed",
    "message": "The operation 'Void' is not allowed on a Sale transaction with result 'Approved' and settlement state 'Settled'.",

    "data": {
      "correlationId": "0123456789abcdef0123456789abcdef"
    },
    "validationErrors": "null"
  }
}
```

### 429

The request was refused because a rate limit was exceeded, or because something a later retry can clear stopped it. A rate limit refusal carries an `application/problem+json` body: wait at least the interval `Retry-After` names before retrying, then back off. Limits are tuned per deployment, so read the allowance from the response headers rather than assuming a fixed ceiling. Any other refusal carries the standard error envelope as `application/json`, and its `error.code` names the cause.

**Content type:** `application/problem+json`

Schema: [`RateLimitProblemDetails`](https://devportal.demo.winkpg.io/docs/api/models/RateLimitProblemDetails.md)

Properties:
- `type` (string) required: The problem type identifier. Always the same value: the failure is the status code itself,  so there is no sub-type for a caller to branch on. (nullable)
- `title` (string) required: A short, human-readable summary of the problem type. (nullable)
- `status` (integer(int32)) required: The HTTP status code, repeated in the body as the problem-details format defines.
- `detail` (string) required: A human-readable explanation of this occurrence of the problem. (nullable)
- `retryAfterSeconds` (integer(int32)) required: How long to wait before retrying, in whole seconds, carrying the same figure as the  `Retry-After` header. Always at least one: a value of zero would invite an immediate  retry that is certain to be rejected again.

## Example request

Every block below sends the same request. Replace {{BASE_URL}} with the address of the API you are calling and {{API_KEY}} with your own key.

The request body is a ContractPlanCreateDto. See the Request body section below for its fields.

These blocks send the Plan without a trial example. The other examples follow under Other request examples.

Adds a plan that charges subscribers 129.90 a month (120.00 plus 9.90 of tax). The opening price is in force from the moment the plan exists; change it later with POST /api/contract-plans/{id}/prices, which keeps every earlier price. The name must be unique within the merchant. The default schedule only seeds a new contract's recurrence, and each contract owns its schedule once created.

## Other request examples

Each example below is one request, shown in every language with the same placeholders.

### Plan with a 14-day trial

Adds a 49.00 monthly plan whose new subscribers start on a 14-day trial: a contract created on the plan with no trial end date of its own is not charged until the trial ends. The trial is a default for new contracts only, so changing it later never moves an existing subscriber.
