Upload a json array of company numbers you wish to monitor that have attributes that have changed.

The most recent data will be available on the day after the event was detected by DueDil, and will be dated as the date upon which the events were detected.

For example, if DueDil detects a change to a company’s status on Monday 23rd November 2020 at 1pm, the company number that had this status change would be contained in the file for 2020-11-23.jsonl.gz specific to your userID to download later, which would be first made available between 00:00 and 23:59 on Tuesday 24th. The file would then be accessible until 24th December 2020 (inclusive).

If DueDil encounters technical problems during the creation of a file for any given day, the company numbers that have changed on that day will be collected into the next day’s file. Once the files have been created, they are immutable; any change detected by DueDil will appear in future dated files.

The company attributes that constitute a change are limited to the following (this list will grow over time; please contact your account manager if there are specific attributes you would like updates for):

A change to company status
A change to the company name
A change to officer appointments (only appointments of new officers, removal of existing officers or changes to appointment statuses constitutes a change; changes to existing officers,e.g. name changes, do not constitute a change but may be supported in a future iteration of Continuous Updates)
Newly filed company financials (in the rare case where there have been alterations to previously submitted financials, these do not constitute a change)
A change to the number of employees
Any changes (modification to an existing address, addition of a new address or the removal of an address) to a company’s registered or trading address
A change to the industrial classification of the company
New Gazette notices
New shareholders, removal of shareholders or a change to an existing shareholding
New beneficial owners, or removal of beneficial owners

The categories field that now appears in the file specifies the updated categories relevant for the entity in question. This can be used to map to the API endpoints that show a data change, thus saving the effort of calling more API endpoints than needed to get the most up-to-date information.
