We are developing a custom document-retention and compliance portal integrated with Microsoft Purview Records Management.
We need users to perform the following native disposition-review actions from our custom UI without opening the Purview portal:
Approve disposal
Extend disposition review
Relabel an item during disposition review
Add disposition reviewers
Microsoft Graph exposes retention-label and disposition-review-stage configuration APIs, but we have not identified a supported public API for submitting these individual pending disposition decisions.
Does Microsoft provide a supported API, SDK, or extensibility mechanism to execute these native disposition-review actions from a custom application while preserving Purview's compliance controls and audit trail? If so, please share the API documentation, required permissions, licensing requirements and supported deployment model.
