Do there any flag/indicator to identify which data attributes is changed/updated in the live streaming API? Eg. if address of a company changes, then is there any field /status which says address of the company has been updated.
No, the “fields_updated” property in the company profile stream is not used.
The filing stream makes use of it to specify when the “links.document_metadata” is added, indicating that the PDF is ready for download.
You would need to keep an up-to-date database of companies and diff the event with your stored version to work out what changed.
