Property Type Description

external_id

string

Reference for this order, supplied by the customer.

When set, external_id makes order idempotent. All requests that use the same external_id after the initial order creation, will result in a response that returns the data of the initially created order. The response will have a 201 response code. These responses fail to create any further orders.

It also allows for retrieving by external_id instead of id only.

### Funding sources There are different ways to pay for gift cards and rewards on Tremendous. Every payment mechanism is called a "funding source". You can retrieve a list of all available funding sources by using the [Funding sources API endpoint](https://developers.tremendous.com/reference/list-funding-sources). The Tremendous API sandbox environment comes with a single funding source that allows you to spend up to $5,000 in *fake money* to test the API. [Learn more about the sandbox environment](https://developers.tremendous.com/docs/sandbox-environment). The HTTP status code `200` on the response will be used to indicate success. After processing successfully the reward gets queued to be delivered to it's recipient (for delivery method `EMAIL` and `PHONE`). Delivery will happen asynchronously, after the response has been sent. ### Idempotence Requests issued with the same `external_id` are idempotent. Submitting an order with an already existing `external_id` will not create a new order. If the payload is the same as a previously issued order, our API will return a `201` response code, along with a representation of the already-existing order in the response body. If the `external_id` used is for an order with different parameters (e.g. amount, recipient), our API will return a `409` response code, indicating a conflicting resource.
