iTwins

Download API definition:

GET https://dev-api.bentley.com/itwins/[?subClass][&status][&type][&number][&displayName][&parentId][&iTwinAccountId][&$search][&$select][&$filter][&$orderby][&$top][&$skip][&includeInactive]

Retrieves a list of iTwins that the calling user is a member of.

Max Return

Some users can be members of a very large number of iTwins. The iTwins API uses the X-Max-Return header to limit the number of iTwins returned from any query.

X-Max-Return

Default Behavior: If not specified, the maximum number of iTwins returned will default to 1000. For example, if a user has access to 40,000 iTwins, only up to 1000 iTwins can be paged through. Attempting to page past 1000 will not result in an error; it will simply stop returning iTwins.
Customizing the Limit: You can set X-Max-Return to any number between 1 and 10,000. Setting a lower value can improve query performance. For instance, if your application displays no more than 500 iTwins, set X-Max-Return to 500.
Response Header: The value of X-Max-Return used in the query is also returned in a response header with the same name.

If you need to get more than 10000 iTwins, use the iTwin Exports API. There is no limit to the number of iTwins that can be exported.

We have added support for advanced odata queries. For simple queries, you can still use the other query parameters (status, type, number, displayName, parentId, iTwinAccountId and $search). The odata $filter allows you to build more advanced queries. You cannot use the advanced odata $filter and the simple query parameters (other than subClass) at the same time.

Example: Find Asset or Project iTwins created since September 1, 2024 that have 'abc' in the displayName. Select only the id, displayName and createdDateTime. Order them by displayName.

/itwins?subClass=Asset,Project&$filter=createdDateTime+ge+2024-09-01T00:00:00Z+and+contains('abc',displayName)&$select=id,displayName,createdDateTime&$orderby=displayName

There are more examples in the parameter definition below.

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.

number

Find all iTwins with the exact number specified. Cannot be used at the same time as the $search parameter.

displayName

Find all iTwins with the exact displayName specified. Cannot be used at the same time as the $search parameter.

parentId

Find all iTwins that are children of the specified parentId.

iTwinAccountId

Find all iTwins that are owned by the specified iTwinAccountId.

$search

Find all iTwins that have the search string anywhere in the number or displayName. Cannot be used at the same time as the number or displayName parameters.

$select

A comma delimited list of iTwin properties to return. Keep the list as small to improve the performance of the query and limit the size of the data returned. If $select is specified then the Prefer header is ignored. If not specified, then the API will return the minimal representation.

$filter

An odata filter used to limit the query results. Use the subClass property to limit to specific subClasses. $filter is used to filter the results even further. All text values in the filter are case insensitive.  Example: &filter=parentId+eq+'78202ffd-272b-4207-a7ad-7d2b1af5dafc'+and+(startswith('ABC',number)+or+startswith('ABC',displayName))

$orderby

Used to order the results.  Example: $orderby=displayName ASC

$top

The $top 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. This sets the page size and should not be confused with the X-Max-Return header.

$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.

Request headers

X-Max-Return

The maximum number of iTwins that will be returned from the query. The default value is 1000 but you can set this to any number between 1 and 10,000. Setting a lower value can improve query performance. Do not confuse this with $top. $top controls the size of a single page. X-Max-Return controls the total count returned from all pages combined.

X-iTwin-Query-Scope

MemberOfiTwin - (Default) The results will be limited to the iTwins that the user is a member of. Use the Access Control API to manage an iTwin's members.
OrganizationAdmin - The results will be limited to the iTwins that belong to the users organization. It can only be used by an organization admin. It is useful for admins that want to query all iTwins in their organization.

Authorization

Yes

OAuth access token with itwin-platform scope

Yes

Setting to application/vnd.bentley.itwin-platform.v1+json is recommended.

Prefer

Indicates a level of details in the response. Valid values are 'return=representation' or 'return=minimal'. The default is 'return=minimal'.
