The API offers methods to request revisions and to get those requested revisions once they have been retrieved.

Requesting and Getting Revisions

Request the revisions for a given document comparison. Revisions requests complete asynchronously. A PCCViewer.RevisionsRequest will be returned that provides events for revisions retrieval progress and members to access retrieved revisions.

Copy Code
// Request revisions
var revisionsRequest = viewerControl.requestRevisions();
// Subscribe to the PartialRevisionsAvailable event to get revisions as they become available
revisionsRequest.on('PartialRevisionsAvailable', function(_event) {
    // Get the newly available revisions
    var newRevisions = _event.partialRevisions;
// Subscribe to the RevisionsRetrievalCompleted event to get revisions when all of them are available
revisionsRequest.on("RevisionsRetrievalCompleted", function(){
    // Get all of the revisions for that comparison
    var revisions = revisionsRequest.getRevisions();
