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.

4. Trading Partners

Adding a Trading Partner

Go to Partners → Add Partner. You will need:

  • Partner name and contact email.
  • Their ISA Sender ID (ISA06) and your ISA Receiver ID (ISA08) for this partner.
  • Connection type (SFTP, AS2, or API webhook).
  • Transaction sets this partner sends/receives.
  • Preferred output mode (EDI or API JSON).

ISA IDs (Interchange Sender/Receiver IDs)

ISA IDs are 15-character alphanumeric identifiers that tell the EDI network who sent a document and who should receive it. Each trading partner relationship uses a unique pair: your sender ID and the partner's receiver ID.

You can find your ISA IDs in Settings → EDI Configuration. If you don't have ISA IDs, SignalEDI will provision them for you during onboarding.

Onboarding Timeline

SignalEDI can prepare account setup and technical configuration in days, not weeks. However, getting certified with a major trading partner takes longer because their internal processes control the timeline — not SignalEDI.

Important: Certifying with major trading partners (large retailers, healthcare payers) typically takes 6–8 weeks due to their internal intake, testing, and certification processes. That timeline is controlled by the trading partner, not SignalEDI platform setup (which is typically ready in days, not weeks). Start the partner onboarding process as early as possible.

Production Readiness Checklist

Before sending live partner traffic, confirm these items in the dashboard or with your managed onboarding owner.

  • Partner ISA IDs, document types, and transport are saved on the trading-partner record.
  • A sample file or API payload has passed validation for each required transaction set.
  • Webhook URL, signature secret, or SFTP/AS2 endpoint is configured and tested.
  • Acknowledgement handling is agreed: 997/999/277 status appears in the transaction lifecycle.
  • Support path, SLA tier, audit-log needs, retention tier, and BAA/DPA review are understood before production PHI or regulated data moves.
