Capabilities

Tools 28

sealsubscriptions_add_items

WRITE: Add products to a subscription. Prices are in the subscription's currency and change what the customer pays on the next charge. An item with one_time=true is removed after the next renewal. PUT /subscription action=add_items.

Discovered
sealsubscriptions_append_rule_product_variants

WRITE: Add products or variants to a subscription rule without touching the ones already linked. PUT /subscription-rule/append-product-variants.

Discovered
sealsubscriptions_apply_discount_code

WRITE: Apply a Shopify discount code to an auto-charging subscription (not to recurring-invoice subscriptions); it lowers what the customer pays on the next charges. PUT /subscription-discount-code action=apply.

Discovered
sealsubscriptions_cancel_customer_subscription

WRITE: Cancel a subscription now: all future charges and shipments stop and the customer may get Seal's cancellation email. It can be brought back with sealsubscriptions_reactivate_subscription. For a later cancellation use sealsubscriptions_schedule_cancellation. PUT /subscription action=cancel.

Discovered
sealsubscriptions_create_charge_now

WRITE: CHARGES THE CUSTOMER'S PAYMENT METHOD IMMEDIATELY for the next billing attempt of the subscription and creates a Shopify order; it does not wait for the scheduled date. Only call it when the user clearly asked for an immediate charge. With reset_schedule=true the later attempts are rebuilt from today. PUT /subscription-create-charge-now.

Discovered
sealsubscriptions_delete_billing_attempt

WRITE: Delete a billing attempt that has not been processed. Seal keeps 65 days of attempts scheduled, so a deleted one is recreated within hours unless the schedule is moved first (see sealsubscriptions_reschedule_billing_attempt). DELETE /subscription-billing-attempt.

Discovered
sealsubscriptions_edit_items

WRITE: Change existing items of a subscription: variant, quantity (> 0), price (>= 0), SKU, one-time flag, properties. Changes what the customer pays on the next charge. PUT /subscription action=edit_items.

Discovered
sealsubscriptions_edit_subscription

WRITE: Edit a subscription's schedule and details: delivery and billing interval (a billing interval longer than the delivery interval makes it prepaid), min/max number of payments, note attributes (an empty list removes them), delivery method and price, and the shipping address. Only the fields you pass change. To change items use the item tools. PUT /subscription action=edit.

Discovered
sealsubscriptions_edit_subscription_rule

WRITE: Edit a subscription rule: its name, the plan selector label (`options`, e.g. "Deliver every") and the products it applies to. Cannot edit selling-plan pricing, billing intervals or automated interval-change rules; use the Seal app for those settings. product_variants REPLACES all products and variants linked to the rule: to add some without removing the others use sealsubscriptions_append_rule_product_variants. PUT /subscription-rule.

Discovered
sealsubscriptions_get_subscription

One subscription with everything Seal knows: customer, shipping and billing address, status, intervals, delivery method, items with discounts, billing attempts (with status and error messages), fulfillment orders, invoices, tags and the activity log. Private customer links are removed. GET /subscription?id=.

Discovered
sealsubscriptions_get_subscription_rule

One subscription rule by id, with its products, variants and selling plans. GET /subscription-rule?id=.

Discovered
sealsubscriptions_list_selling_plans

Read a subscription rule's complete selling plans, including initial/fixed and recurring pricing policies, cycle thresholds, billing and delivery intervals. Returns Seal's original field names and values. Read only: Seal's public API does not support editing these policies or reading/creating/updating automated interval-change rules; configure those in the Seal app. Does not change existing contracts. GET /subscription-rule?id=.

Discovered
sealsubscriptions_list_subscription_rules

List the subscription rules (plans) of the shop: name, payment type, the products and variants they apply to and their selling plans. GET /subscription-rules.

Discovered
sealsubscriptions_list_subscriptions

List or search the shop's subscriptions (up to 50 per page; pass next_cursor as cursor for the next page): status, customer, interval, total value, shipping address and card brand/last digits. Search by customer email, first or last name; filter by status; optionally include the items and the billing attempts of each. GET /subscriptions.

Discovered
sealsubscriptions_list_subscriptions_by_billing_date

Subscriptions that have at least one billing attempt scheduled between two UTC date-times: the way to see what will be charged tomorrow or this week. Each subscription carries a cursor; pass the last one's cursor as `cursor` to get the next page. GET /subscriptions-by-billing-date.

Discovered
sealsubscriptions_list_webhooks

List the webhooks registered for this shop through the API (topic and address). GET /webhooks.

Discovered
sealsubscriptions_pause_subscription

WRITE: Pause an active subscription: no further charges or shipments until it is resumed. Undo with sealsubscriptions_resume_subscription. PUT /subscription action=pause.

Discovered
sealsubscriptions_process_charge

WRITE: CHARGES THE CUSTOMER'S PAYMENT METHOD NOW for one specific billing attempt (for example a failed or upcoming one) and creates a Shopify order. Only call it when the user clearly asked for that charge. PUT /subscription-process-charge.

Discovered
sealsubscriptions_reactivate_subscription

Discovered
sealsubscriptions_remove_discount_code

WRITE: Remove a discount code from a subscription. Use the discount code id from the subscription's items[].discount_codes[].id (a uuid), not the code text. DELETE /subscription-discount-code.

Discovered
sealsubscriptions_remove_items

WRITE: Remove items from a subscription by item id. The customer stops receiving and paying for them. PUT /subscription action=remove_items.

Discovered
sealsubscriptions_reschedule_billing_attempt
