All top-level API resources have support for fetches via "list" API methods. For instance, you can list redemptions, list publications, list customers, and list products. These list API methods share a common structure, taking at least these three parameters: limit, page, and created_at .

Parameter name	Description
`limit`	A limit on the number of objects to be returned, between 1 and 100.
`page`	Which page of results to return.
`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`.

Parameter name

Description

limit

A limit on the number of objects to be returned, between 1 and 100.

page

Which page of results to return.

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.

Response format

The listing method returns a dictionary with a data property that contains an array of up to limit resources. Each entry in the array is a separate object. If no more resources are available, the resulting array will be empty. The result can be narrowed down according to specified (or default) filters.

Property name	Description
`object`	A string describing the object type returned.
`total`	Total number of records for given filtering query
`data_ref`	A value for this property directs to the property name which points to the results array

Shortcuts

"List" API methods offer a list of query parameters which easily allows filtering results. Each API resource enables a specific set of options which can be used for simplifying a query. If you need advanced options, you can 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`

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 describing 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`

Advanced filters for qualification API

Examine qualifications methods display all vouchers or campaigns qualified to the given customer and context (e.g., order). Using the advanced filters listed below you can limit qualification results:

Resource	Filter	Example
Campaigns	category	[filters][categories][conditions][$is]={{category_name}}
Campaigns	voucher type (DISCOUNT_VOUCHER, GIFT_VOUCHER or LOYALTY_CARD)	[filters][voucher_type][conditions][$is]={{voucher_type}}
Campaigns	metadata	[filters][metadata.{{Campaign metadata key}}][conditions][$is]={{campaign_metadata_value}}
Voucher	category	[filters][categories][conditions][$is]={{category_name}}
Voucher	voucher type (GIFT_VOUCHER, or DISCOUNT_VOUCHER)	[filters][type][conditions][$is]={{voucher_type}
Voucher	metadata	[filters][metadata.{{Voucher metadata key}}][conditions][$is]={{voucher_metadata_value}}
Voucher	holder_id (when a code is published to a customer, he/she becomes its holder)	[filters][holder_id][conditions][$in]={{customer_id}}
Voucher	campaign_ids	[filters][campaign_id][conditions][$in]={{campaign_id}}
