Purge object and element caches

Available since 2021 Update 8


You can try these workflows with REST API Playground.

When a user works with MicroStrategy, cache data is created. The data stored in the cache allows to increase system performance and improve user’s experience. Instead of loading the data required by system from some database, i.e., meta-data database, the data is retrieved from a cache memory. However, Platform Administrator or Analytics Architect may decide to purge the caches periodically. Currently, the REST API allows to delete cache data for objects and elements using a following endpoint:

  • DELETE /api/monitors/projects/{projectId}/cache/{cacheType}

The DssXmlPrivilegesCacheAdministration privilege is required to purge element or object caches.


The sections below present Cache Management REST API usage.

  • X-MSTR-AuthToken
    • (Required) MicroStrategy authorization token.
    • Data Type: string
    • Allowable Values: valid authorization token.

Path parameters

  • projectId
    • (Required) Unique project identifier.
    • Data Type: string
    • Allowable Values: project identifier (GUID)
  • cacheType
    • (Required) Determines whether object or element cache data is deleted.
    • Data Type: string
    • Allowable Values: "element" or "object"


There are two steps which you need to take to delete cache for objects and elements. The steps are described in this section.

Step 1 – Getting project id

The purpose of the first step is to determine project id. The id identifies the project for which we want to clear the cache. We can use a following endpoint to list all loaded projects with their ids.

Endpoint: GET /api/projects

You can call the endpoint using for example curl command:

curl -X 'GET' \
'' \
-H 'accept: application/json' \
-H 'X-MSTR-AuthToken: m0pjr6ec9lemv0m8782hd8hg48'

The X-MSTR-AuthToken is an authentication token which you receive during authentication process. The correct response of the endpoint should look like:

"acg": 255,
"id": "B7CA92F04B9FAE8D941C3E9B7E0CD754",
"name": "MicroStrategy Tutorial",
"status": 0,
"alias": "",
"description": "MicroStrategy Tutorial project and application set designed to illustrate the platform's rich functionality. The theme is an Electronics, Books, Movies and Music store. Employees, Inventory, Finance, Product Sales and Suppliers are analyzed.",
"dateCreated": "2015-06-30T21:55:35.000+0000",
"dateModified": "2022-06-25T12:48:15.000+0000",
"owner": {
"name": "Administrator",
"id": "54F3D26011D2896560009A8E67019608"
"acg": 255,
"id": "CE52831411E696C8BD2F0080EFD5AF44",
"name": "Consolidated Education Project",
"status": 0,
"alias": "",
"description": "",
"dateCreated": "2016-11-20T16:39:48.000+0000",
"dateModified": "2022-06-25T12:46:22.000+0000",
"owner": {
"name": "Administrator",
"id": "54F3D26011D2896560009A8E67019608"

Please find the id for the desired project. For example, id of the project: “MicroStrategy Tutorial” is B7CA92F04B9FAE8D941C3E9B7E0CD75. We will use it in the next step.

Step 2 – Deleting the cache

You need to invoke a following endpoint to delete the cache:

Endpoint: DELETE /api/monitors/projects/{projectId}/caches/{cacheType}

The endpoint path consists of the projectId parameter, so you must replace the placeholder with the id value. The last placeholder determines the cache type to be purged. The allowable values follow element or cache. The example below demonstrates how to call the endpoint using a curl command:

curl -X 'DELETE' \
'' \
-H 'accept: */*' \
-H 'X-MSTR-AuthToken: m0pjr6ec9lemv0m8782hd8hg48'

The endpoint should return: 204 No Content.


The default response is 204 No Content which notifies that the cache purge was triggered. The endpoint can also return another response codes. The codes are listed below.
