Authorization	SAS token generated as specified in Shared Access Signature Authentication with Service Bus.

Request body

The following patch operations are allowed:

JSON-Patch operation	Installation Property	Description and sample
add	PushChannel	Update the channel of an installation. `[ { "op": "add", "path": "/pushChannel", "value": "aaaaaaa"} ]` Put expiredPushChannel to true if pushChannel is changed.
add	UserId	Update or add user ID value. `[ { "op": "add", "path": "/userId", "value": "Bob"} ]`
add	Tag	If value is array, add all tags in array to existing tags (even if not present). If value is a string, add tag to current array (or create a new array with single value, if not tags are currently present). `[ { "op": "add", "path": "/tags", "value": "tag"} ]`
add	Template (P2)	Update or add whole template. `[ { "op": "add", "path": "/templates/myTemplate", "value": '{"body": "…", "tags": ["tag"]}'} ]`
add	Template body/header/expiry/tags	Update or add parts of template (note that 'add' on headers replaces current headers object). Add on tags has the same semantics as native tags. `[ { "op": "add", "path": "/templates/myTemplate/body", "value": '{"aps": …}'} ]` `[ { "op": "add", "path": "/templates/myTemplate/headers", "value": '{"X-WNS-Type": "wns/toast"}'} ]`
add	secondaryTile channel	Updates the secondaryTile channel. `[ { "op": "add", "path": "/secondaryTiles/myTile/pushChannel", "value": "aaaaaaa"} ]`
add	secondaryTile tag	Same as tags update but path refers to secondary tile. `[ { "op": "add", "path": "/secondaryTiles/myTile/tags", "value": '["fooTag"]'} ]`
add	secondaryTile template	Same as normal templates but path refers to tileId.
add	secondaryTile template body/header/expiry/tags	Same as normal templates but path refers to tileId.
Remove	As above	Deletes a property, such as userID, or an element of the tags array. If the last tag of the tags property is removed the whole property is removed. `[ { "op": "remove", "path": "/tags/myTag"} ]`
Replace	As above	Semantically equivalent to remove+add.
