Resmark API: Orders

An order in Resmark is a completed purchase with associated date/time and customer information. Orders created through the API are automatically marked as paid by an external source. No real payment processing occurs, and customer email notifications are disabled by default.

Orders created through the API are automatically marked as paid. No real payment is collected. If you want the customer to receive a confirmation email, set disableConfirmationEmail to false.

Create New Reseller Order

POST /order

Uses the same endpoint and parameters as Create New Order. The difference is that you use a Reseller Cart ID (created through the reseller cart endpoint with supplierId) as the id parameter.

Cancel Order

DELETE /order/{id}

Cancels an entire order and returns all inventory seats to availability.

Parameter	Type	Required	Description
id	string	Yes	Order ID or Confirmation ID
applyCancellationFee	boolean	No	Set to `false` to suppress cancellation fees.

Cancel Inventory Item

DELETE /order/{id}/item/{itemId}

Cancels a specific date/time from an order that contains multiple items. Useful when the customer needs to cancel one activity but keep the rest of the order.

Parameter	Type	Required	Description
id	string	Yes	Order ID or Confirmation ID
itemId	string	Yes	Inventory ID for the date/time to cancel
applyCancellationFee	boolean	No	Set to `false` to suppress cancellation fees.

Cancel Participant

Cancels a specific participant from an order item, returning their seat to availability.

Parameter	Type	Required	Description

itemId	string	Yes	Inventory ID for the date/time
participantId	string	Yes	Participant ID from the order's `participantList` (e.g., `HfU`)
applyCancellationFee	boolean	No	Set to `false` to suppress cancellation fees.

Cancel Unit

DELETE /order/{id}/item/{itemId}/unit/{unitId}

Cancels a specific unit from an order item. This is used for rental-type products that have a unitList instead of a participantList.

Parameter	Type	Required	Description
id	string	Yes	Order ID or Confirmation ID
itemId	string	Yes	Inventory ID for the date/time
unitId	string	Yes	Unit ID from the order's `unitList` (e.g., `HUy`)
applyCancellationFee	boolean	No	Set to `false` to suppress cancellation fees.

Cancellation Levels

The API provides four levels of cancellation granularity:

Cancel Order — cancels everything on the order
Cancel Inventory Item — cancels one date/time from a multi-item order
Cancel Participant — cancels one person from an activity-type item
Cancel Unit — cancels one unit from a rental-type item

All cancellation endpoints accept applyCancellationFee: false to waive fees. If omitted, the account's configured cancellation policy applies.
