Fetching Data

Learn how to specify the data you would like to fetch.

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, consuming at least these three query 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`

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.
`total`	Total number of records for given filtering query.
`data_ref`	The value for this property indicates the property name containing the results array.

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, 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`
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.

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 the qualification results.

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}}`
