Capabilities

Tools 21

smartrr_cancel_customer_subscription

WRITE, DESTRUCTIVE: cancel a customer's subscription in the merchant's store (this is the customer's Smartrr subscription, not your usefulapi plan). It stops all future orders and charges; the reason may trigger Smartrr's configured cancellation emails or actions. It can be undone only with smartrr_resume_subscription. Get reason_id from smartrr_list_cancellation_reasons. PUT /vendor/customer/{customerId}/purchase-state/{subscriptionId}/cancel.

Discovered
smartrr_get_analytics

Active subscription count and active subscriber count for each day in a date range. GET /vendor/analytics-simple.

Discovered
smartrr_get_bill_history

The audit trail of one bill: every status change, retry and error. GET /vendor/bill/{billId}/history.

Discovered
smartrr_get_order

One order by its Shopify order id (the `shopifyId` field in smartrr_list_orders, passed as shown). GET /vendor/orders/{shopifyId}.

Discovered
smartrr_get_subscription

One subscription by its Shopify subscription id (the `shopifyId` field from smartrr_list_subscriptions, passed exactly as shown): status, schedule, next billing date, line items, discounts, shipping address, customer and payment method (brand, last digits and expiry only). GET /vendor/purchase-state/{shopifySubscriptionId}.

Discovered
smartrr_get_subscription_bills

Billing attempts of one subscription (amount, status pending/processing/succeeded/failed/canceled, billing date, retry count, error), by its Shopify subscription id. GET /vendor/purchase-state/{shopifySubscriptionId}/bills.

Discovered
smartrr_get_subscription_events

The 250 most recent events on a subscription (pause, skip, cancel, activate, billing attempts and failures, line-item and address changes, discounts) with who did it. GET /vendor/purchase-state/{shopifySubscriptionId}/events.

Discovered
smartrr_get_subscription_orders

Orders generated by one subscription, by its Shopify subscription id. GET /vendor/purchase-state/{shopifySubscriptionId}/orders.

Discovered
smartrr_list_bills

List billing attempts across all subscriptions with amount, status (pending, processing, succeeded, failed, canceled), billing date, retry count, error and the subscription and customer. Filter by billing date; `status` filters the returned page only (use page_size 100 and next_page to cover more). Bill ids are numbers. GET /vendor/bill.

Discovered
smartrr_list_cancellation_reasons

The cancellation reasons configured in Smartrr (id, type, text, action, retention discount). Use an `id` as reason_id when cancelling a subscription. GET /vendor/cancellation-reasons.

Discovered
smartrr_list_customer_subscriptions

List the subscriptions of one customer, by Smartrr customer id (`custRel.id` from smartrr_list_subscriptions, or `id` from smartrr_list_customers). GET /vendor/customer/{customerRelationshipId}/purchase-state/.

Discovered
smartrr_list_customers

List Smartrr customers (subscribers) with email, name, phone, order count, total spent and custom attributes. Search by email fragment or filter by Shopify customer id. GET /vendor/customer-relationship.

Discovered
smartrr_list_orders

List orders Smartrr has synced from Shopify (subscription and one-time) with totals, status, financial and fulfillment status, tracking, items and customer. Filter by processed date or order label (e.g. #1001). GET /vendor/order.

Discovered
smartrr_list_selling_plan_groups

The store's subscription programs (selling plan groups) and their plans: name, options, delivery and billing frequency, discounts. GET /vendor/selling-plan-group.

Discovered
smartrr_list_subscriptions

List customer subscriptions (Smartrr 'purchase states') with status, next billing date, selling plan, line items, shipping address, discounts and the customer (id, email, name). Filter by status, next billing date or creation date. The ids you need for the other tools: `id` (subscription id), `custRel.id` (customer id) and `shopifyId` (Shopify subscription id). GET /vendor/purchase-state.

Discovered
smartrr_pause_subscription

WRITE: pause a customer's subscription until a date: no orders or charges are created while it is paused, then it resumes on that date. Reverse it with smartrr_resume_subscription. Takes the customer id and subscription id from smartrr_list_subscriptions. PUT /vendor/customer/{customerId}/purchase-state/{subscriptionId}/pause.

Discovered
smartrr_resume_subscription

WRITE: reactivate a paused or cancelled subscription; the customer will be billed on next_billing_date and every cycle after. Customer-facing: it restarts charges to the customer's card. PUT /vendor/customer/{customerId}/purchase-state/{subscriptionId}/activate.

Discovered
smartrr_retry_bill

WRITE, CHARGES THE CUSTOMER: retry a billing attempt now. If it succeeds the customer's saved payment method is charged for the bill amount and the order is created.

Discovered
smartrr_unskip_order

WRITE: restore a previously skipped order of a subscription, so it is billed and shipped again. `date` is the skipped order date; omit it to restore the earliest skip. PUT /vendor/customer/{customerId}/purchase-state/{subscriptionId}/unskip.
