Change monitoring and webhooks
A one-off check gets stale quickly. A company's board changes, tax debt appears or liquidation starts, and you usually only hear about it once an invoice is already unpaid. Add your portfolio's registry codes to monitoring and get notified as soon as something important changes.
What you get
Every change as a JSON event to your system (signed, with retries).
A daily or weekly email to your team, only when something changed.
Add and remove companies via API or upload a CSV. Thousands of codes in one portfolio.
Track only what matters to you: e.g. just tax debt and status, or everything.

Frequently asked questions
How quickly do notifications arrive?
We check register and tax debt changes daily, so you usually receive the notification the morning after the change.
Is there a free option for individual companies?
Yes. With an entity.ee account you can follow up to 50 companies and see changes on your account page. Webhooks, large portfolios and teams are the business solution.
Where does the data come from?
From the Estonian Business Register open data and the Centre of Registers and Information Systems, the Tax and Customs Board, GLEIF (LEI), the Official Gazette (Ametlikud Teadaanded) and the public procurement register. Register changes reach us daily, full annual report data monthly.
