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.

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.
