To integrate with an API you can use either one of our pre-integrated solutions which are Greenhouse, SmartRecruiters or JazzHr. If you don't use one of our pre-integrated ATS' it is possible integrate your own system using our API access key.
To get the API key please go to Settings and choose Integrations.
On the same page, you can find the input to enter webhook URL, which will allow you to receive updates from Devskiller, just after candidate status will change.
If you decide to integrate your system on your own, you can find the whole API documentation here: https://api.devskiller.com/
