Fetching Data

All top-level API resources have support for fetches via list API methods. For instance, you can list redemptions, list publications, list customers, list products, and more.

These list API methods share a common structure, using at least these query parameters: limit and created_at.

Parameter name	Description
`limit`	A limit on the number of objects to be returned; between 1 and 100.
`created_at`	A filter on the list based on the object `created_at` field. The value is a dictionary with the following options: `before`, `after`. A date value must be presented in ISO 8601 format (`2016-11-16T14:14:31Z` or `2016-11-16`). Examples: - `[created_at][before]=2017-09-08T13:52:18.227Z` - `[created_at][after]=2017-09-08`

Paging the results

Some of the list API methods use the page query parameter to display another page of results.

However, the following list API methods use the starting_after_id query parameter:

The response to these methods may include a more_starting_after key that takes a string value with an ID. Use this ID with the starting_after_id query parameter to display another page of results.

Response format

The listing method returns a dictionary with a data property that contains an array of resources. The maximum number of resources returned is determined by the limit query parameter. If no more resources are available, the resulting array on a given page will be empty. The result can be narrowed down according to the specified (or default) filters.

Property name	Description
`object`	A string describing the object type returned.
`data_ref`	The value for this property indicates the property name containing the results array.
`data`	An array that contains objects for a given list endpoint. In older methods, this is replaced by the name of the respective resource, e.g. `publications`.
`total`	Total number of records for given filtering query. In some methods, this field is absent.
`has_more`	It indicates that there are more results to be returned for given filter parameters.
`more_starting_after`	Present in some of the newer endpoints; it provides an ID that can be used with a `starting_after_id` query parameter to return another page of results.

Shortcuts

List API methods offer a list of query parameters. These parameters allow you to filter the results. Each API resource enables a specific set of options which can be used for simplifying a query. If you need advanced options, read the next section.

Resource	Shortcuts	Example
Vouchers	`customer` `campaign` `category`	`{api-url}/vouchers?customer=source_id`
Redemptions	`campaign_name` `customer` `voucher_code` `related_object_id` `related_object_parent_id`	`{api-url}/redemptions?customer=customer_id` `{api-url}/redemptions?customer=source_id`
Customers	`email` `name`	`{api-url}/[email protected]`
Publications	`campaign_name` `customer_id` `voucher_code` `result` `voucher_type` `is_referral_code` `parent_object_id` `related_object_id`	`{api-url}/publications?campaign_name=TEST`
Validation Rule Assignments	`related_object_id` `rule`	`{api-url}/validation-rules-assignments?related_object_id=promo_id`

Advanced filters for fetching resources

Moreover, API methods for fetching resources offer extended capabilities for filtering data. A user can build advanced queries by passing parameters that define search criteria.

Resource	Examples
Vouchers	`[filters][active][conditions][$active]=true` `[filters][active][conditions][$expired]=true` `[filters][active][conditions][$enabled]=true` `[filters][active][conditions][$disabled]=true` `[filters][redemption.redeemed_quantity][conditions][$is]=0` `[filters][is_referral_code][conditions][$is]=true` `[filters][metadata.seq_number][conditions][$is]=1`
Campaigns	`[filters][metadata.seq_number][conditions][$is]=1` `[filters][metadata.test][conditions][$is]=true`
Products and Skus	`[filters][updated_at][conditions][$after][0]=2020-08-20T14:17:09Z` `[filters][updated_at][conditions][$before][0]=2020-08-20T14:17:09Z` `[filters][created_at][conditions][$after][0]=2020-08-20T14:17:09Z` `[filters][created_at][conditions][$before][0]=2020-08-20T14:17:09Z`
List all promotion stacks	`[created_at][before]=2021-12-30T13:52:18.227Z` `[created_at][after]=2021-12-30T13:52:18.227Z` `[filters][created_at][conditions][$before][0]=2021-12-30T13:52:18.227Z` `[filters][created_at][conditions][$after][0]=2021-12-30T13:52:18.227Z` `[updated_at][before]=2021-12-30T13:52:18.227Z` `[updated_at][after]=2021-12-30T13:52:18.227Z` `[filters][updated_at][conditions][$before][0]=2021-12-30T13:52:18.227Z` `[filters][updated_at][conditions][$after][0]=2021-12-30T13:52:18.227Z`
