B2 Reversal Request (F6)
This is the standard NCPDP Telecommunication F6 spec, with 0 loops and 6 segment positions.
The OpenEDI JSON, the C# template and the ediFabric Native JSON are available for download by request. Open a support ticket to ask for them.
Use the B2 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 B2 files into TSB2 objects. See ediFabric .NET.
ediFabric Native
Native supports X12 today, and NCPDP is coming. When it's available, map version F6 to this Native model with set_map to parse B2 files to JSON from Python, Java, C or C#. See ediFabric Native.
OpenEDI
The OpenEDI file for this transaction is available for download by request, with the C# template and the Native JSON. Read about OpenEDI.
Generate B2 classes in Python, Java, Node.js, Go, Rust or C
The OpenEDI file describes each B2 as JSON. To work with B2 data as typed objects, generate classes from the OpenEDI file in your language; the root class is TSB2. 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.
