Stigg Subscriptions — Lifecycle Operations

This skill covers day-to-day subscription operations: provision, preview, update, cancel, trials, multi-subscription products, and plan-version migration (moving an existing sub from plan v1 to plan v2 after a publish).

Before You Start

Per the umbrella stigg skill: search first. Provisioning options, billing-cycle behavior, and trial-conversion semantics evolve. Open the relevant SDK / REST page (Mintlify Stigg docs MCP) before authoring.

The Operation Map

Op	Purpose	Reference
Provision	Create a subscription for a customer on a plan (+ add-ons, trial, billing details)	references/provisioning.md
Preview	Calculate pricing for a hypothetical subscription before provisioning	inline below
Update	Change an active subscription's plan / add-ons / period / quantities / spend / coupons / trial	references/updates.md
Cancel	End a subscription immediately, at end-of-period, or on a specific date	inline below
Trials	Start a trial, convert to paid, handle expiry	references/trials.md
Multiple active subscriptions	One customer, many subscriptions, scoped by resourceId	inline below
Plan-version migration	Move an existing sub from plan v1 to plan v2 (after a publish)	references/plan-version-migration.md

Provision a Subscription

Minimal backend call

const sub = await stigg.provisionSubscription({
  customerId: 'customer-123',
  planId: 'plan-pro',
  billingCountryCode: 'US',           // required for paid plans w/ price localization
});

The provisioning surface includes (see references/provisioning.md for the full list):

• Resource ID — required when the product allows multiple active subscriptions.
• Billing period — monthly / annual / etc., for paid plans.
• Plan configuration — unit quantities for in-advance commitment charges and variable entitlements; price overrides.
• Add-ons — list of add-ons (and quantities) compatible with the plan.
• Subscription start date — Immediately (default) / EndOfCurrentBillingPeriod (if an active paid sub already exists) / SpecificDate (past = back-dated, no immediate charge; future = activates on date).
• Free trial — applicable to paid / custom plans.
• Spend management — minimumSpend, maximumSpend.
• Discounts — applied coupons (catalog-wide or ad-hoc subscription-specific).
• Payment method — automaticallyUsePaymentMethodOnFile / generate-an-invoice / no-payment-via-Stigg.
• Billing cycle anchor — UNCHANGED (default) / NOW.
• Proration — ProrateNow / ProrateOnNextInvoice / NoProration.

Generous-entitlement rule: when a customer's effective entitlements come from multiple sources — active subscription, add-ons, trial, promotional entitlements, additional product subscriptions — Stigg picks the most generous value across all of them. The "trial vs paid" case is just one instance of this rule; it applies whenever sources overlap.

Preview a Subscription

Before provisioning, preview the immediate and recurring invoices:

const preview = await stigg.previewSubscription({
  customerId: 'customer-123',
  planId: 'plan-pro',
  billingPeriod: 'MONTHLY',
  addons: [{ addonId: 'addon-seats', quantity: 10 }],
  couponId: 'SAVE20',                          // optional
  subscriptionId: 'sub-789',                   // optional — preview an UPDATE to an existing sub
});

Node SDK / GraphQL returns immediateInvoice and recurringInvoice with each amount as a { amount, currency } Money object (lowercase subtotal). Direct REST callers see a flatter DTO with scalar amounts and the field name subTotal (capital T). Amounts are in full dollars / units of the currency, not cents — 49 means $49.00 (Stripe convention is the opposite, this catches Stripe-savvy devs). See references/provisioning.md for the full shape and previewSubscription use cases.

Update a Subscription

Critical: updateSubscription (the GraphQL mutation) does not support changing the plan. To change a subscription's plan, call provisionSubscription again — Stigg routes it through the right mechanism (in-place update or replace, depending on plan-type transition; see the migration matrix below).

// Update — addons, billing period, billable features, price overrides
await stigg.updateSubscription({
  subscriptionId: 'sub-123',
  addons: [{ addonId: 'addon-seats', quantity: 10 }],
  billingPeriod: 'ANNUAL',
});

// Change plan — re-provision (NOT updateSubscription)
await stigg.provisionSubscription({
  customerId: 'customer-123',
  planId: 'plan-pro',          // new plan
  // ...other provisioning fields
});

What updateSubscription directly supports (per the GraphQL mutation surface):

• Billing period (paid plans, e.g. MONTHLY → ANNUAL).
• Add-ons (replaces existing — pass the new full list).
• Billable features (in-advance commitment quantities, per-unit quantities).
• Price overrides.

Other update flows surfaced by the Stigg app UI (trial extension / shortening, spend-limit changes, coupon application, billing-cycle anchor reset, proration on the change) flow through separate SDK methods or provisionSubscription re-calls — search the docs for the specific operation.

Scheduled updates replace, don't queue: a new update overrides any pending scheduled update and applies immediately (documented for the Stigg app UI; SDK behavior generally matches — confirm in your SDK's docs).

Detailed flow + patterns: references/updates.md.

Cancel a Subscription

Via @stigg/node-server-sdk (which translates to the cancelSubscription GraphQL mutation):

await stigg.cancelSubscription({
  subscriptionId: 'sub-789',                              // Node SDK uses subscriptionId
  subscriptionCancellationTime: 'END_OF_BILLING_PERIOD',  // or 'IMMEDIATE' / 'SPECIFIC_DATE'
  // endDate: '2026-06-01T00:00:00Z',                     // required when SPECIFIC_DATE
  // subscriptionCancellationAction: 'DEFAULT',           // or 'REVOKE_ENTITLEMENTS'
  // prorate: false,
});

Field-name note: Node SDK uses subscriptionId. Python / Go / Ruby / Java / .NET SDKs and the raw GraphQL mutation use subscriptionRefId. Direct REST takes the ID in the URL path.

subscriptionCancellationTime:

Value	Behavior
IMMEDIATE	Cancel immediately.
END_OF_BILLING_PERIOD	Cancel at the end of the current billing period. Default for most products. Not applicable to custom-priced plans or trial subscriptions.
SPECIFIC_DATE	Cancel on the date specified by endDate. Not applicable for trial periods.

subscriptionCancellationAction:

Value	Behavior
DEFAULT	Product's default cancellation behavior (revoke access or downgrade to free, per product policy).
REVOKE_ENTITLEMENTS	Immediately revoke all entitlements upon cancellation.

States after cancel: CANCELED (already ended) or CANCELLATION_SCHEDULED (pending).

Direct REST users (calling https://api.stigg.io/api/v1 via curl): the unprefixed REST field names are cancellationTime, cancellationAction, endDate, prorate. Same enum values.

Trials

Trials apply to paid and custom plans. The plan defines the default trial; provisioning can override it.

• Provision with trial — pass trial config at provision time.
• Convert trial → paid — provision a paid subscription on top; Stigg starts the paid plan at the trial end.
• Trial expired without conversion — fires the trial.expired event; trigger win-back from your app.
• One trial per customer per product in self-served flows (admin overrides exist).
• Customers who already paid are not eligible for another self-serve free trial.

Multiple Active Subscriptions Per Customer

For multi-tenant products (workspaces / projects / apps), a single customer holds many subscriptions, scoped by resourceId:

const sub = await stigg.provisionSubscription({
  customerId: 'customer-123',
  resourceId: 'workspace-abc',
  planId: 'plan-team',
});

Once enabled (it's a product-level setting, fixed at product creation):

• Pass resourceId on every relevant call — provision, update, entitlement check, usage report, paywall widget.
• The customer can have separate plans on each workspace, all paid with the same payment method.
• Trial vs paid: at most one active trial and one active non-trial subscription per (customer, resource) pair.
• Combine with single-instance products (set the other product to "single active subscription") to model "account + sub-accounts" / "platform + app instances" — e.g., Webflow's account + per-site model.

Once a product has any subscriptions, you cannot toggle multi-active on/off. Decide at product creation.

Plan-Version Migration (Catalog v1 → v2)

When a plan is republished, existing subscriptions stay on the old version unless migrated. Routine, ongoing operation.

Catalog-side publish flow (drafts, version policy, what triggers grandfathering) lives in stigg-pricing-modeling/references/plans.md. This section is the subscription-side migration mechanics.

Two migration mechanisms, picked automatically by Stigg based on the plan-type transition:

Path	Mechanism	Why
Free → Paid	Provision new subscription	Paid plans need billable metric values.
Free → Custom	Provision new subscription	Custom plans need values for variable entitlements.
Paid → Free	Migrate to latest version	In-place.
Paid → Custom	Migrate to latest version	In-place; the existing external-billing-system subscription is not canceled — only Stigg-side metadata is removed.
Custom → Paid	Provision new subscription	Paid plans need billable metric values.
Custom → Free	Migrate to latest version	In-place.

Triggering migration:

• UI: open the subscription, ⋮ → Migrate to latest → pick Immediately or At end of current period.
• Programmatic: the migrate-subscription mutation / SDK method. Allows gradual rollout.

If migration is immediate and the customer's current price differs from the latest published price, Stigg auto-charges or credits the prorated amount.

Detailed migration reference: references/plan-version-migration.md.

• Runtime entitlement checks / usage reporting → stigg-entitlements.
• Strategic advice on pricing models → stigg-pricing-expert.

Common Mistakes

Mistake	Fix
Forgetting resourceId on multi-active products	Every call (provision / update / entitlement / usage / widget) needs it.
Treating scheduled updates as a queue	A new update replaces scheduled ones. If you need a queue, model it in your app.
Cancelling immediately when the product policy says end-of-period	Use the product's default; opt-in to immediate only when you mean it.
Trying to cancel a custom-priced plan at end of period	Not supported by the cancellation modal. Use a specific date or coordinate with billing.
Self-serve trial for a customer who's already paid	Not eligible. Admin override needed. Surface the right CTA in your app.
Skipping previewSubscription before charging	Customers expect to see what they'll pay. Preview first, then provision.
Not setting billingCycleAnchor: NOW on a major upgrade	The customer's bill cycle drifts. Reset explicitly when the change should start a fresh period.
