Get my recently used iTwins - iTwins

REST API Overview

Reference

iTwins

Download API definition:

GET https://api.bentley.com/itwins/recents[?subClass][&status][&type][&$top][&$skip][&includeInactive]

Retrieves a list of recently used iTwins for the calling user. A user can only have 25 recently used iTwins. They are returned in order with the most recently used iTwin first in the list.

When a user accesses your application you can use the Add iTwin to my recents API to mark the iTwin as recently used. If there are already 25 recents, then the oldest one will be removed to make room for the new one.

Inactive iTwins

iTwins with status=Inactive are not returned by default. This improves query performance and reduces clutter in user interfaces by filtering out unused iTwins. You should still provide a way for users to see their Inactive iTwins if they request them. In the API, you can do this by setting the status parameter or by using the includeInactive parameter.

If status=Inactive, the API will return only Inactive iTwins.
If includeInactive=true, the API will return all iTwins (Active, Trial and Inactive).

The includeInactive parameter is optional and defaults to false. A 422 error will be returned if you try to use a status parameter at the same time as the includeInactive parameter.

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

Any user can call this endpoint. It will only return iTwins that the user is a member of. Use the Access Control API to manage an iTwin's members.

Request

Request parameters

subClass

Specify a particular subClass that you wish to query on. The subClass is optional but queries will be faster if specified and we recommend specifying it whenever possible. You can specify more than one by using a comma delimited string. Example: subClass=Asset,Project will find all Assets or Projects matching your query criteria.

status

Specify a particular status that you wish to query on.

type

Specify a particular type that you wish to query on.

$top

The $top system query option requests the number of items in the queried collection to be included in the result. The default is 100. The max is 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.

includeInactive

By default, the query will not return Inactive iTwins unless you set includeInactive=true. Cannot be used at the same time as the status parameter.
