Get an order by idempotency key

Path Parameters

The order's idempotency key.

Order idempotency keys must be unique per account.


Returns: Order object


The order's unique identifier


Account-unique identifier provided by the client.

idempotency_key has two purposes:

  1. Clients can safely retry order requests without accidentally performing the same operation twice. The current state of the original order is returned.
  2. Clients can use idempotency_key to reconcile orders with other entities on their system.

  • quantity
  • value

Order creation timestamp

bundlesarray of objectrequired

bundles are set when the order's status is placed, paid, retiring or complete.

The bundles associated with the order including their relative quantity and cost breakdown.

projectsarray of objectrequired

Projects are set when the order's status is retiring or complete.

The projects associated with the order including their relative quantity and cost breakdown.

Orders are placed against bundles, not projects. Projects in a bundle may change based on supply.

This property is set as soon as we can guarantee project supply.


Carbon credits PDF certificate URL.

This property is set when an order has state 'complete'

The property is set (and the certificate is available) regardless of the Sustainability page configuration.

The URL requires API authentication and cannot be accessed anonymously.


The Carbon credits certificate public URL.

Once the Sustainability page of the associated account is enabled and configured to include the certificate section, and the order is set to 'complete', this URL will link to the publicly accessible certificate.


An arbitrary dictionary (key-value pairs) to store application-specific information.

Lune doesn't use this information for order processing. Its purpose is for the API clients to be able to attach arbitrary information (to an order for example) and then retrieve it.


The offset link identifier, if the order was placed through an offset link


End-user email.

This property is currently populated on orders placed through offset links.
