SIGNL4 API
Use our API for systems integration or to build your own use cases. Sample scenarios include but are not limited to: 2-way integration: Triggering of Signls and updates in the third party systems when alert state changes occur Retrieving alarms for logging purposes Calendar integrations: Creation and management of on-call duties Punch users in and out based on external calendars etc. AUTHENTICATION Using the API requires an API key, which you can generate in the SIGNL4 portal under 'Developers'. This key must then be specified in a special header in every HTTP request. This header is called X-S4-Api-Key . The base URL of the API is https://connect.signl4.com/api/ . Copyright © Derdack GmbH
