Create a subscription
The subscriptions.create operation: POST /api/v1/subscriptions in the REST API and the subscriptions_create tool in the MCP server.
/api/v1/subscriptionsStarts a subscription of a customer to one or more recurring prices (spec §16.2). The prices must share a currency, and their intervals must be whole multiples of each other (monthly with yearly). A customer has at most one live item per metered price's meter.
- Trial:
trialEnd, elsetrialDays(0 = none), else the prices' shortest trial. The subscription istrialingand nothing is invoiced until the trial ends; free plans have no trial. - Free plans (only zero-amount licensed prices) are
activeat once, with no invoice and no payment method. - First invoice: licensed items for the first period, with the coupon or promotion code applied, taxed now
with the customer's stored location evidence (a new sale: a blocked location is refused). A later
billingCycleAnchorbills a prorated first period (prorationBehavior: nonebills nothing until then). A zero total isn't issued. - Collection:
charge_automaticallycharges the invoice to the customer's saved payment method (paymentMethodId, else their default): the subscription isincompleteuntil the payment succeeds (23 hours at most). Without a saved payment method the answer carriespaymentSetup.url, a hosted checkout in setup mode where the customer saves one; the first invoice is charged right after.send_invoiceemails the invoice with the bank transfer details and isactiveat once.
Emits subscription.created (and invoice.issued/invoice.finalized for the first invoice); the customer's
entitlements are recomputed. Dry-run it to see the first invoice before charging anyone.

Body
A JSON object (Content-Type: application/json):
| Field | Type | Required | Description |
|---|---|---|---|
customerId | cus_… ID | Yes | The customer (cus_…). |
items | array of object | Yes | The recurring prices: one currency; intervals that are whole multiples of each other. |
items[].priceId | price_… ID | Yes | A recurring price (price_…). |
items[].quantity | integer (1 to 1000000) | No | Seats or units of a licensed price (1 to 1,000,000). Metered prices take no quantity. |
collectionMethod | one of charge_automatically, send_invoice | No | charge_automatically (the default payment method is charged) or send_invoice (the invoice is emailed with bank transfer details and paid by the due date). |
daysUntilDue | integer (0 to 365) | No | send_invoice: days from an invoice's issue date to its due date (default 14). |
trialDays | integer (0 to 730) | No | Trial days (0 = no trial). Default: the shortest trial of the prices. |
trialEnd | date-time | No | When the trial ends (instead of trialDays). |
trialEndBehavior | one of convert, cancel_if_no_payment_method, pause_if_no_payment_method | No | What happens at the trial's end without a payment method: convert (bill anyway), cancel_if_no_payment_method or pause_if_no_payment_method. |

promotionCode | string | No | A promotion code as the customer typed it (case doesn't matter). |

prorationBehavior | one of create_prorations, always_invoice, none | No | With a later billingCycleAnchor: create_prorations and always_invoice charge the partial first period now; none bills nothing until the anchor. |
paymentMethodId | pm_… ID | No | A saved payment method of the customer (pm_…); default: the customer's default method. |
setupSuccessUrl | string | No | Without a payment method (charge_automatically): where the setup checkout sends the customer after saving one. |
usageThreshold | object | No | Invoice metered usage as soon as what it would charge reaches this amount (spec §16.7): limits the credit risk of usage-heavy customers. In the subscription's currency, whole minor units. |
usageThreshold.amount | string | Yes | Integer micros as a string (12500000 = 12.50). |
usageThreshold.currency | string | Yes | ISO 4217 currency code: the price's currency. |
metadata | object | No | Your own key-value pairs (at most 50 keys). On updates the whole set is replaced. |

Errors
| Code | HTTP status | When | What to do |
|---|---|---|---|
validation_failed | 400 | A field is malformed or out of range. | Fix the fields listed in details.issues and send the request again. |
resource_not_found | 404 | No subscription (or customer, price, coupon) with this ID is visible to the request. | Check the ID and that your credentials are scoped to the right organization, entity, brand and mode. |
customer_deleted | 400 | The customer was deleted. | Create a new customer for this buyer. Deleted customers stay readable for the records they belong to, but can't be changed. |
subscription_price_invalid | 400 | A price isn't recurring, is archived, is in another currency, or its interval doesn't combine with the others. | Use active recurring prices of one currency whose intervals are whole multiples of each other (monthly with yearly, weekly with 2-weekly). details.reason says what's wrong and param names the item. |
subscription_meter_conflict | 409 | The customer already has a live subscription item for a metered price's meter. | Change the existing subscription's metered item instead, or cancel it first. A customer has at most one active metered item per meter. |
subscription_payment_method_invalid | 400 | paymentMethodId isn't a saved, attached payment method of the customer. | Use a saved payment method (pm_…) of the subscription's customer that isn't detached, or leave it out to use the customer's default. |
subscription_anchor_invalid | 400 | billingCycleAnchor is before the start or too far ahead. | Set billingCycleAnchor after the subscription starts (after the trial, if any) and at most one of its longest interval later, or leave it out to bill from the start. |
coupon_not_redeemable | 409 | The coupon is archived, expired or used up. | Check details.reason: reactivate an archived coupon, or create a new coupon when it expired or reached its redemption limit. |
promotion_code_not_redeemable | 409 | The promotion code can't be used for this customer or amount (details.reason). | Check details.reason and tell the customer: the code may have expired, be used up, belong to another customer, need a larger purchase or be for first-time customers only. |
registration_required | 422 | An invoice issued now can't be taxed: the seller isn't registered where the customer is (a new sale). | Register the entity for the regime named in details.regime (see its prerequisites and deadline), or arm the jurisdiction once the prerequisites are done. The customer can join the waitlist meanwhile. |
jurisdiction_blocked | 422 | The customer's location is blocked for new sales. | This jurisdiction isn't covered by usable tax knowledge for this seller. Contact support if you need to sell there. |
evidence_conflict | 422 | The customer's stored location evidence isn't enough to tax an invoice issued now (§13.3). | Collect another piece of location evidence (billing address, card country, or the customer's confirmation of their country) and quote again. |
invoice_bank_transfer_missing | 409 | send_invoice: the entity has no bank transfer details to put on the first invoice. | Add the IBAN, BIC, bank name and account holder in the entity's invoice settings, then send the invoice again. A send_invoice invoice tells the customer where to pay. |
permission_denied | 403 | The credentials can't change this brand's subscriptions (subscriptions:write). | Ask an organization owner or admin for a role or scope that allows this action. |
entitlement_required | 403 | The organization's plan doesn't include subscriptions (subscriptions.enabled). | Upgrade the organization's plan, or remove something to get back under the limit. |
org_suspended | 403 | Live mode, while the organization is suspended (§37.5). | If this is your organization, pay the open Ownrecord invoice in Organization → Billing; it is active again as soon as it is paid. Renewals, refunds, the customer portal and filings keep working. |
It can also return these common errors: api_version_unsupported, invalid_json, unsupported_media_type, authentication_required, api_key_invalid, scope_required, idempotency_key_required, idempotency_key_reused, idempotency_in_progress, approval_required, approval_rejected, approval_expired, stale_approval, approval_policy_denied, rate_limited, internal_error.
