REQEST Request Message (4.0)
This is the standard EDIG@S 4.0 spec, with 11 loops and 18 segment positions, as OpenEDI JSON, an ediFabric C# template and an ediFabric Native model. To change it for a trading partner, customize it in the EDI Spec Builder.
Use the REQEST spec in your code
ediFabric .NET
Add the C# template and its common files to your project, or reference the template NuGet package, and read REQEST files into TSREQEST objects. See ediFabric .NET.
ediFabric Native
Native supports X12 today, and EDIG@S is coming. When it's available, map version 4.0 to this Native model with set_map to parse REQEST files to JSON from Python, Java, C or C#. See ediFabric Native.
OpenEDI
Select Customize in Spec Builder to copy the spec under your own name, change it for your partner, and parse files against it in EdiNation, ediFabric Native or ediFabric Cloud. Read about OpenEDI.
Generate REQEST classes in Python, Java, Node.js, Go, Rust or C
The OpenEDI file describes each REQEST as JSON. To work with REQEST data as typed objects, generate classes from the OpenEDI file in your language; the root class is TSREQEST. The classes keep the loops, segments, lengths and code lists, but not the EDI data formats. Read more in Generate a class from OpenEDI.
Python: datamodel-code-generator. Node.js: openapi-typescript. Java, Go, Rust and C: OpenAPI Generator.
