D1 Predetermination of Benefits Request (D.0)
This is the standard NCPDP Telecommunication D.0 spec, with 0 loops and 11 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 D1 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 D1 files into TSD1 objects. See ediFabric .NET.
ediFabric Native
Native supports X12 today, and NCPDP is coming. When it's available, map version D.0 to this Native model with set_map to parse D1 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 D1 classes in Python, Java, Node.js, Go, Rust or C
The OpenEDI file describes each D1 as JSON. To work with D1 data as typed objects, generate classes from the OpenEDI file in your language; the root class is TSD1. 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.
