Standard WOPI request and response headers

In addition to the request/response headers listed here, this operation may also use the Standard WOPI request and response headers.


The response to a EnumerateAncestors call is JSON (as specified in RFC 4627) containing the following required properties:


An array of JSON-formatted objects containing the following properties:


The name of the container without a path. This value should match the Name property in a CheckContainerInfo response. Required.


A URI to the container, including a valid access token. Required.


This property includes an access token and thus has important security implications. See Preventing ‘token trading’ for more details.

The array must always be ordered such that the ancestor closest to the root is the first element.

If there are no ancestor containers, this property should be an empty array.

Sample response

Consider a file in the following container hierarchy: /root/grandparent/parent/myfile.docx. When called on this file, the EnumerateAncestors operation should return the following:

  "AncestorsWithRootFirst": [
      "Url": "http://.../wopi*/containers/<containerId>?access_token=<per_container_token>",
      "Name": "root"
      "Url": "http://.../wopi*/containers/<containerId2>?access_token=<per_container_token2>",
      "Name": "grandparent"
      "Url": "http://.../wopi*/containers/<containerId3>?access_token=<per_container_token3>",
      "Name": "parent"
