How do I alert my users when a company they follow posts a job?

To alert your users when a company they follow posts a job, create a TheirStack saved job search for those companies by domain or company list, and attach a webhook pointing at your backend. Each new matching job sends an event as soon as we discover it, which you turn into an in-app alert.

Can I alert users when a job closes?

Yes, TheirStack sends a job closed webhook event for each matching job once we confirm it is gone from its source, usually within 24 hours. A closed senior role is often a sign that a new decision-maker was hired, which makes it a useful alert for sales users.

Can I alert users when a new company matches their criteria?

Yes, attach a webhook to a TheirStack saved company search and you get an event the first time each company matches your user's criteria, such as a technology, industry or hiring filter. It fires once per company per webhook and costs 3 API credits, so users hear about new accounts without repeat alerts.

What happens if my backend is down when a webhook fires?

TheirStack retries a webhook delivery that fails for 48 hours, so an event is not lost when your backend is down for a while.

Alert

Alert your users the moment an account moves
