VenditPublicSdk 2024.5.7.2

Vendit Public API C# Library

Building a project using Json files from Swagger documentation has not yet reached the schema maturity of older (Soap) technologies. In order to ease the pain, this c# package should get you up and running faster. Without the need of manually changing generated integers to decimals or Enums...

The API's at https://api2.vendit.online/ can be used by utilizing this client.

This lib is also conveniently available as a NuGet package:

dotnet add package VenditPublicSdk

A minimalistic example, getting today's order ID's (ignoring pagination, so up to 100 orders):

VenditPublicClientSettings settings = new VenditPublicClientSettings
{
    ApiKey   = "XxXxXxXxXxXxXxXxXxXxXx",
    Username = "Xx Keep Secret :-) xXx",
    Password = "XxXxXxXxXxXxXxXxXxXxXx",
};
VenditPublicClient client   = new VenditPublicClient(settings);
int[] todaysOrderIds = (await client.FindOrder(OrderFields.OrderDate, DateTime.Today, FilterComparison.GreaterOrEqual)).Results;

More extensive example

Console application that dumps todays orders (max 100) including details to the console output in Json format.

Here we persist the token and the expiry date improving performance (saves a round-trip to get a token on subsequent calls) and slightly increasing security since the credentials are not sent with each use. It is recommended to do something similar in your applications.

Note that you should have separate API Keys for multiple applications or they should have a mechanism for sharing the token. As soon as a new Token is retrieved, the older token will no longer be valid. Having separate API Keys will also help when troubleshooting.

Usage: Run the program once, then fill in your credentials in the ApiSettings.config file, and run again.
