SignalEDI documentation

API-first EDI docs for onboarding, X12 basics, trading partner setup, billing, REST endpoints, and webhooks — with JSON/CSV intake, instant validation, and real-time visibility.

Authentication

All API requests require a Bearer token. Generate an API key from Settings → API Keys.

GET /api/v1/transactions
Authorization: Bearer sk_live_YOUR_API_KEY
Content-Type: application/json

Security: Never expose your API key in client-side code or public repositories. If a key is compromised, revoke it immediately from the Settings page.
