Marker-based Pagination

Marker-based Pagination

APIs that use marker-based paging use the marker and limit query parameters to paginate through items in a collection.

Marker-based pagination is often used in cases where the length of the total set of items is either changing frequently, or where the total length might not be known upfront.

Paging

To fetch the first page of entries in a collection the API needs to be called either without the marker parameter, or with the marker set to 0. The limit parameter is optional.

curl https://api.box.com/2.0/folders/0/items?limit=100&usemarker=true \
    -H "authorization: Bearer ACCESS_TOKEN"

APIs that support both offset-based pagination and marker-based pagination require the usemarker query parameter to be set to true to ensure marker-based pagination is used.

To fetch the next page of entries the API needs to be called with an marker parameter that equals value of the next_marker value that was received in the API response.

curl https://api.box.com/2.0/folders/0/items?marker=34332423&limit=100&usemarker=true \
    -H "authorization: Bearer ACCESS_TOKEN"

The final page of items has been requested when the next next_marker value is null in the response object. At this point there are no more items to fetch.

With marker-based paging there is no way to determine the total number of entries in a collection except by fetching them all. Applications should not retain the next_marker value long-term as the internal implementation of the markers may change over time.

Marker & Limit

The following query parameters are used to paginate a collection.

Query parameterTypeDefault
markerStringThe first position in the collection to return results from. This should be a value that was returned in a previous request.
limitIntegerDepends on APIThe maximum number of entries to return. If the value exceeds the maximum, then the maximum value will be used.
usemarkerBooleanAn optional query parameter that can be used with API endpoints that support both types of pagination to select pagination type. Set to true to enforce marker-based pagination.

Collections

When paginating collections, the API returns an object that contains the set of results as an array, as well as some information about the current page of results.

FieldType
entriesArrayThe page of items for this page. This will be an empty array if there are no results.
next_markerStringThe value that can be used as the marker value to fetch the next page of results. If this value is null or an empty string there are no more results to fetch.
limitIntegerThe limit used for this page of results. This will be the same as the limit query parameter unless it exceeded the maximum value allowed for this API endpoint.
