Get iModel Changesets - iModels

REST API Overview

Reference

iModels

Download API definition:

GET https://dev-api.bentley.com/imodels/{id}/changesets[?$top][&$skip][&$orderBy][&afterIndex][&lastIndex]

Retrieves a list of Changesets for the iModel specified by the iModel id.

Changesets form a linear timeline of the iModel changes. For more information on creating and retrieving Changesets using iTwin.js see working with Changesets.

Notes

The Prefer header can be used to specify how much result metadata is desired by the client. The Prefer request header field is used to indicate that particular server behaviors are preferred by the client but are not required for successful completion of the request.

This operation supports "return=representation" and "return=minimal" preferences.

The "return=representation" preference indicates that the client prefers that the server include an entity representing the current state of the resource in the response to a successful request. The "return=minimal" preference indicates that the client wishes the server to return only a minimal response to a successful request. This is the default preference if Prefer header is not specified.

Authentication

Requires Authorization header with valid Bearer token for scope itwin-platform.

For more documentation on authorization and how to get access token visit OAUTH2 Authorization page.

Authorization

User must have imodels_webview permission assigned at the iModel level. If iModel Role permissions at the iModel level are configured, then user must additionally have at least imodels_webview permission assigned at the iTwin level. If permissions at the iModel level are not configured, then user must have imodels_webview permission assigned at the iTwin level.

Alternatively the user should be an Organization Administrator for the Organization that owns a given iTwin the iModel belongs to.

For more information please refer to Account Administrator documentation section on Access Control API documentation page.

Note: download property requires user to have at least imodels_read permission. If user has only imodels_webview permission download will always be null.

Rate limits

All iTwin Platform API operations have a rate limit. For more documentation on that visit Rate limits and quotas page.

Request

Request parameters

Yes

iModel id

$top

The $top query option requests the number of items in the queried collection to be included in the result. E.g. to return only first collection item provide the following query: $top=1. When $top parameter is not provided default is set to 100. $top value cannot exceed 1000.

$skip

The $skip query option requests the number of items in the queried collection that are to be skipped and not included in the result. E.g. to return items from the collection starting at the third place provide the following query: $skip=2.

$orderBy

The $orderBy query option allows clients to request ascending using 'asc' or descending using 'desc' order of the returned collection by one or more item properties. Currently the only supported property for Changesets is 'index'. When neither 'asc' or 'desc' keyword is specified the collection is sorted in ascending order. To sort the collection in descending order provide 'desc' keyword e.g.: $orderBy=index desc

afterIndex

The afterIndex query option allows clients to query Changesets which have an index that is greater than the one specified in the query. E.g. to return Changesets that have an index greater than or equal to 2 provide the following query: afterIndex=1. This query option is useful when user wants to query the most recent Changesets starting from the one that is already present in the local copy of the iModel. This can be used together with lastIndex option to specify Changeset index range, afterIndex denotes an exclusive start of the range.

lastIndex

The lastIndex query option allows clients to query Changesets which have an index that is less than or equal to the one specified in the query. E.g. to return Changesets that have an index less than or equal to 10 provide the following query: lastIndex=10. This can be used together with afterIndex option to specify Changeset index range, lastIndex denotes an inclusive end of the range.
