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
Plan the first integration safely
The access fields below come from the connected directory. Their likely implementation impact is explained without assuming provider-specific behavior.
Authentication
OAuth is reported. Confirm flows, scopes, consent, token lifetime, and refresh rules.
Transport
HTTPS is not confirmed. Do not send credentials or production data until secure transport is verified.
Browser access
CORS is unknown. Treat direct browser access as unconfirmed and test before choosing a client-only architecture.
First-request sequence
- Identify the current base URL, version, and endpoint for the use case.
- Confirm how credentials are issued and where they may be stored.
- Test success, invalid input, throttling, unavailable data, and timeouts.
- Record response fields, pagination, caching, and error shapes.
- Add monitoring, retries with backoff, and an appropriate fallback.
Questions to resolve before production
Pricing and quotas
Confirm current plans, free-tier limits, overages, and request ceilings.
Endpoint coverage
Check that the operations and response fields match the intended workload.
Reliability
Look for uptime history, a status page, support routes, and service commitments.
Data and privacy
Review retention, licensing, regional processing, and compliance requirements.
Versioning
Confirm the active version, change policy, deprecation window, and migration guidance.
Developer experience
Validate SDKs, examples, error formats, pagination, and test environments.
