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, using at least these query parameters: limit and created_at.

Parameter nameDescription
limitA limit on the number of objects to be returned; between 1 and 100.
created_atA 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 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 three methods includes a more_starting_after key that takes a string value with an event ID. Use this event ID with the starting_after_id query parameter to page the 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 nameDescription
objectA string describing the object type returned.
totalTotal number of records for given filtering query.
data_refThe value for this property indicates the property name containing the results array.

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.
