Willo

Willo is an asynchronous ("one-way") video interviewing and screening platform that lets teams invite candidates to record answers to pre-defined questions on any browser or device with no downloads, apps, or login required. The Willo Integration API V2 exposes the platform's UI actions as a public REST API so you can embed video interviewing into a job board, ATS, CRM, or staffing platform - managing Departments (Companies), Interviews (jobs and their questions), Participants (candidates) and their video Responses, Message Templates, Users, Webhooks, and Interview Templates. Authentication is by an integration key (API key) from the Willo Integrations page, sent in the Authorization header over HTTPS.

Willo publishes 9 APIs on the APIs.io network, including Child Organisations API, Departments API, Interview Templates API, and 6 more. Tagged areas include Video Interviewing, Recruitment, HR Tech, ATS, and Screening.

Willo’s developer surface includes authentication, documentation, signup flow, support, changelog, engineering blog, and 10 more developer resources.
