GET /exchange/v1.0/complianceCases

List compliance cases - Purview eDiscovery / DSR / Insider Risk case containers. Use ?caseType= to scope.

Backing cmdlet: Get-ComplianceCase. Role: Compliance.IPPS.Read (Community).

Parameter	In	Type	Description
`caseType`	query	string	Filter by case type (eDiscovery \| DSR \| InsiderRisk \| AdvancedEdiscovery \| …).
`recentOnly`	query	bool (switch)	Limit to cases opened recently (no specific timeframe - server-defined).
`roleGroup`	query	string	Filter by role group with case access.

List all compliance cases

Enumerate Purview compliance cases (eDiscovery, DSR, Insider Risk, Advanced eDiscovery) visible to the calling principal. Backed by Get-ComplianceCase on the IPPS pool. Optional ?caseType=eDiscovery filters by case kind. Per-case RBAC applies: even with Compliance.IPPS.Read.All, the SP must be a MEMBER of each case it lists individually via GET /complianceCases/{key} - membership is managed in the Purview portal.

POST /exchange/v1.0/complianceCases

POST /complianceCases - create a new compliance case. Required: name. Optional: caseType, description, externalId, sourceCaseType, secondaryCaseType. Returns 201 + Location.

Re-fetch skipped by design. Block 2 live-verify 2026-05-28 confirmed that Get-ComplianceCase rejects the creator SP with ComplianceCaseMemberTaskException (“you’re not a member of this compliance case”) IMMEDIATELY after New-ComplianceCase succeeds - Compliance.IPPS.ReadWrite.All grants create rights but NOT auto-membership. Doing the standard re-fetch turns a successful create into a 500 + orphans the new case in the tenant. Instead we return 201 with a stub built from the request body; the caller must be added as a case member in the Purview portal before subsequent GET /complianceCases/{key} / PATCH / DELETE work.

Backing cmdlet: New-ComplianceCase. Role: Compliance.IPPS.ReadWrite (Enterprise).

Parameter	In	Type	Required
`name`	body		yes
`caseType`	body
`description`	body

`secondaryCaseType`	body

`dryRun`	query	bool (switch)

Create a Purview compliance case

Provision a new Purview compliance case via New-ComplianceCase on the IPPS pool. Required: name. Optional: caseType (eDiscovery | DSR | InsiderRisk | AdvancedEdiscovery - default eDiscovery), description, externalId (ticketing system id), sourceCaseType, secondaryCaseType. After create, the calling SP automatically becomes the case’s creator/owner - but PER-CASE eDiscovery membership in Purview is still required for any other principal to access the case. Block 2 ships this endpoint to unblock /caseHoldPolicies self-service (which needs a parent case GUID).

GET /exchange/v1.0/complianceCases/{key}

Get a single compliance case by Identity. Requires per-case membership in Purview (see class remarks). Returns 404 if absent.

Backing cmdlet: Get-ComplianceCase. Role: Compliance.IPPS.Read (Community).

PATCH /exchange/v1.0/complianceCases/{key}

PATCH /complianceCases/{key} - partial update. Pass {“close”: true} to close, {“reopen”: true} to reopen. Returns 200 + post-Set case.

Backing cmdlet: Set-ComplianceCase. Role: Compliance.IPPS.ReadWrite (Enterprise).

Parameter	In	Type
`caseType`	body
`close`	body	boolean (switch)
`description`	body
`externalId`	body
`name`	body
`reopen`	body	boolean (switch)
`dryRun`	query	bool (switch)

Close (or reopen) a compliance case

State-flip the case via Set-ComplianceCase on the IPPS pool. Pass {“close”: true} to close, {“reopen”: true} to reopen. These are SwitchParameters in the cmdlet - the controller forwards them only when the JSON value is exactly true. The two switches are mutually exclusive; sending both yields a cmdlet-side parameter conflict (500 with cmdlet error envelope). Block 2 omits -Confirm because the cmdlet rejects it (IPPS family-wide convention).

DELETE /exchange/v1.0/complianceCases/{key}

DELETE /complianceCases/{key} - remove a case. Returns 204.

Backing cmdlet: Remove-ComplianceCase. Role: Compliance.IPPS.ReadWrite (Enterprise).

Parameter	In	Type	Required	Description
`dryRun`	query	bool (switch)

Delete a compliance case

Removes a Purview compliance case by Identity. Backed by Remove-ComplianceCase (IPPS pool). The calling service principal must be a member of the case in the Purview portal even with Compliance.IPPS.ReadWrite.All.
