Subscriptions

Recurring billing — plans, stored payment methods, and the subscription lifecycle. Access via zenpays.subscriptions.

JavaScript only

The Python SDK does not yet expose a subscriptions namespace. Call the REST endpoints directly from Python.

Plans

A plan defines what is charged and how often. Subscriptions attach a customer to a plan.

createPlan

const plan = await zenpays.subscriptions.createPlan({
  name: 'Pro Monthly',
  amount: 2999,
  currency: 'USD',
  interval: 'month',
  description: 'Pro tier, billed monthly',
  intervalCount: 1, // 3 + 'month' would be quarterly
  trialDays: 14,
})

Parameter	Type	Required	Description
name	string	Yes	Plan name shown to customers
amount	number	Yes	Amount charged each interval, in the currency's minor unit
currency	string	Yes	ISO 4217 currency code
interval	'day' | 'week' | 'month' | 'year'	Yes	Billing interval
description	string	No	Longer plan description
intervalCount	number	No	Intervals between charges. Defaults to 1
trialDays	number	No	Free trial length in days
metadata	Record<string, unknown>	No	Arbitrary key/value data

Returns a SubscriptionPlan.

listPlans

const plans = await zenpays.subscriptions.listPlans()

Returns SubscriptionPlan[] for the authenticated merchant.

archivePlan

Stops new subscriptions on the plan. Existing subscriptions continue to bill.

const plan = await zenpays.subscriptions.archivePlan('plan_xxx')

getPublicPlan

Unauthenticated plan details, safe to render on a hosted subscribe page.

const plan = await zenpays.subscriptions.getPublicPlan('plan_xxx')

Payment methods

To charge a subscription automatically you need a stored payment method. Collect one on the client with a setup token, then store the resulting provider token.

createSetupToken

const setupToken = await zenpays.subscriptions.createSetupToken({
  customerId: 'cust_xxx',
  customerEmail: '[email protected]',
  currency: 'USD',
})

Parameter	Type	Required	Description
customerId	string	Yes	Customer the method will belong to
customerEmail	string	Yes	Customer email
currency	string	No	Currency the method will be charged in
tspProvider	string	No	Force a specific payment provider

storePaymentMethod

const method = await zenpays.subscriptions.storePaymentMethod({
  customerId: 'cust_xxx',
  customerEmail: '[email protected]',
  tspToken: 'tok_from_provider',
  tspProvider: 'stripe',
  type: 'card',
  last4: '4242',
  brand: 'visa',
  expiryMonth: 12,
  expiryYear: 2028,
})

tspToken is the provider token representing the instrument the customer entered. Raw card details never reach ZenPays.

listPaymentMethods

const methods = await zenpays.subscriptions.listPaymentMethods('cust_xxx')

revokePaymentMethod

await zenpays.subscriptions.revokePaymentMethod('spm_xxx')

Subscription lifecycle

create

const subscription = await zenpays.subscriptions.create({
  customerId: 'cust_xxx',
  customerEmail: '[email protected]',
  planId: 'plan_xxx',
  storedPaymentMethodId: 'spm_xxx',
})

Parameter	Type	Required	Description
customerId	string	Yes	Customer to subscribe
customerEmail	string	Yes	Customer email
planId	string	Yes	Plan to subscribe them to
storedPaymentMethodId	string	No	Method to charge. Omit to require setup first
tspProvider	string	No	Force a specific payment provider
metadata	Record<string, unknown>	No	Arbitrary key/value data

list

const all = await zenpays.subscriptions.list()
const active = await zenpays.subscriptions.list('active')

Optionally filtered by SubscriptionStatus.

get

const subscription = await zenpays.subscriptions.get('sub_xxx')

cancel

Cancels at the end of the current billing period by default.

// At period end — the customer keeps access until currentPeriodEnd
await zenpays.subscriptions.cancel('sub_xxx')

// Immediately
await zenpays.subscriptions.cancel('sub_xxx', { immediately: true })

pause

const subscription = await zenpays.subscriptions.pause('sub_xxx')

resume

const subscription = await zenpays.subscriptions.resume('sub_xxx')
