InHouse EDI API allows you to run EdiNation's EDI translation and validation API in your own cloud or on-prem environment(s).
The Inhouse API provides the following operations to run in your environment as opposed to running in our cloud:
- Read EDI (parsing X12, EDIFACT, HL7, etc. files)
- Write EDI (generating X12, EDIFACT, HL7, etc. files)
- Validate EDI (validating X12, EDIFACT, HL7, etc. messages)
- Acknowledge EDI (generating TA1, 997, 999 for X12, and CONTRL for EDIFAC)
These, commonly called EDI translation & validation operations, are the only ones from the managed EDI API that require unencrypted EDI files for processing.
The main goals of the Inhouse API are:
- To preserve sensitive EDI data by allowing you to execute all the translation & validation operations on your servers under your control. Your, or your partner's EDI files never leave your network and you don't have to worry about third-party dependencies, SOC2 or HIPAA compliance, or signing BAAs.
- To allow you to ramp up and down infrastructure, cloud or on-prem, when you need it.
- To provide modern, composable building blocks for EDI translation, that can be shared between the teams in your organization.
Difference between the Managed API and the InHouse API
The InHouse API should be substitutable with its managed counterpart so that you are able to switch between the two by simply swapping the URL from one to the other.
Managed EdiNation EDI API
The Managed edition of the API is hosted in our own Azure cloud subscription. You don't need to install anything in your environments/servers and all EDI translation and validation are carried out on our servers.
To use any of the API methods you need to send your EDI data/files to our servers for processing.
The Managed API also comes with model management operations and the Web EDI Analyzer, which only works with the managed edition.
Inhouse EdiNation EDI API
The In-house edition of the API is hosted in your own cloud or on-prem environments. You need to download and install the API.
All EDI translation and validation operations are carried out in your environment and your sensitive EDI data/files never leave it. You are able to ramp up/down infrastructure when you need it.
None of the model operations are included in the InHouse API and you'll still need access to the Managed API if you want to create or modify custom models. The Web EDI Analyzer is also available only for the Managed API and there is no in-house version.
The following functionality remains available only in the Managed API/Web EDI Analyzer:
- Import SEF
- Model management
- Viewing/downloading EDI models
- EDI Analyzer
- EDI to JSON converter
The Inhouse API is written in .NET 6 (same as the cloud EDI API) and is provided as two DLL files (additionally two NuGet packages are also included):
To use the InHouse API you need to obtain a valid API key. The API key is delivered to your account in the Web EDI Analyzer, as well as by email after you sign up for a free trial.
Every method of the InHouse API has an API key parameter, where you include your API key.
The API key is sent to an Auth API that sits in our cloud (same as the Managed API). Upon successful validation of the API key, the Auth API returns a token that is valid for 30 days. This means that no more calls to the Auth API will be made for some time.
A few days before the token expires, another call to the Auth API will be made to refresh the token for another 30 days.
The URL for the Auth API must be set as an environment variable - EDINATION_AUTHAPI_URL.
In order for the InHouse API to successfully retrieve the authentication token, you need to allow external HTTP GET calls to the Auth API, currently accessible at:
The Managed API automatically loads the models corresponding to an EDI type, either automatically or explicitly using the models API. All model management operations are missing from the InHouse API, therefore, models are loaded from the Auth API.
Every time a new model is required, e.g. an X12 837P is read for the first time, a call to the Auth API is made to retrieve all models for the X12 HIPAA version and cache them locally in the InHouse API. Models are loaded in .NET's app domain, the same as the authentication token, and remain there until the app domain is unloaded (due to app restart or infrastructure ramping up/down).
To retrieve models from the Auth API, you need to allow external HTTP GET calls to the Auth API.
As mentioned above, all model operations remain in the Managed API, therefore, if you want to import SEF files, create new models from scratch or modify existing ones, you still need to do this in the Managed API (either via the API or the Web EDI Analyzer).
Custom models are used in the same way as in the managed operation - by supplying the model parameter for the Read operation, and the Model property in the JSON request for the rest of the operations.
The provided examples for using the InHouse API as Azure Function and AWS Lambda show you how to utilize the API in the same way as the Managed API, adhering to the same EdiNation API Reference and EdiNation API Docs.
In reality, the InHouse EDI API is located in the EdiFabric.Api.dll (or EdiFabric.Api.nupkg) and is a set of .NET services:
Each service corresponds to the supported EDI standard, and provides the following methods:
ReadAsync(Stream input, Stream utf8JsonOut, string apiKey, ReadParams rParams)
string ReadAsync(Stream input, string apiKey, ReadParams rParams)
WriteAsync(Stream utf8JsonIn, Stream output, string apiKey, WriteParams wParams)
string WriteAsync(Stream utf8JsonIn, string apiKey, WriteParams wParams)
ValidateAsync(Stream utf8JsonIn, Stream utf8JsonOut, string apiKey, ValidateParams vParams)
string ValidateAsync(Stream utf8JsonIn, string apiKey, ValidateParams vParams)
Acknowledge EDI - for X12 and EDIFACT only
GenerateAckAsync(Stream utf8JsonIn, Stream utf8JsonOut, string apiKey, AckParams aParams)
string GenerateAckAsync(Stream utf8JsonIn, string apiKey, AckParams aParams)
All methods expect the input to be binary (.NET Stream), regardless of if it's EDI file contents or JSON.
There are two options for the output - either receive it as binary (.NET Stream) or as a string.
All methods are async (return a .NET Task), expect a valid API key, and have an optional set of parameters.
To get started with InHouse API, sign up for a trial, and download the product and Visual Studio examples. The trial is free for 14 days and you can run it on as many environments as you want.
Another way to evaluate the functionality is to simply use the Managed API. Switching from the Managed API to the InHouse is seamless.
During the trial, you can access the Auth API from anywhere. However, all ongoing subscriptions require a single IP address from which all HTTP GET calls will be initiated. We care about security and all calls from IP addresses not on the whitelist will be discarded.
Please contact us for a quote if you need to use more than one IP address. We only accept single IP addresses or lists of individual IP addresses and not IP ranges.
License and service terms
The InHouse API offers the option of operating fully in off-line mode, e.g. without calls to the Auth API, in the event that the Auth API is down for whatever reason.
We have procedures in place to send you instructions on how to configure the API to operate offline by manually installing the token and models into your environment until the Auth API is back up.
This procedure provides all standard models, however, if you use custom models, we recommend that you maintain a local backup of them, either as OpenAPI (in JSON or YAML format) or as DLL files.
The product contains EdiFabric.dll which is an edition that can only be used with EdiFabric.Api.dll. You won't be able to use this edition of EdiFabric on its own or as a substitute for a product you previously obtained from edifabric.com.
API calls quota and rate
All subscribers to EdiNation InHouse can still use the Managed EDI API and the Web EDI Analyzer with the same API key as the Auth API. The following limitations are in force:
|API||Max calls/month (quota)||Max calls/minute (rate)|
|Managed/Web EDI API||1,500||60|
When the quota is exceeded, the caller receives a
403 Forbidden response status code. When the call rate is exceeded, the caller receives a
429 Too Many Requests response status code.
