TipsTrade.Dvla.Model 1.0.0.2

TipsTrade.Dvla

Provides access to the DVLA APIs:

• DVLA MOT History API
• Vehicle Enquiry Service API

This package replaces TipsTrade.DVLA, and resets the version to 1.x

Breaking changes

Version 1 contains breaking changes:

• Uses the new MOT History API (confusingly v.1)
• Rename namespaces to TipsTrade.Dvla
• Deprecate TipsTrade.DVLA.MOTHistory.Model
• Remove TipsTrade.DVLA.MOTHistory.MOTClient
• Add DvlaClient which is usable with dependency injection and provides access to both the MOT History APIs and Vehicle Enquiry APIs

MOT API usage

API keys are required

using TipsTrade.Dvla;

// Configure services

services.AddHttpClient(); // If not already done
// Add DvlaClient with a singleton MotMemoryAuthStateProvider (You can implement your own provider which could be scoped).
services.AddDvlaClient<CredentialProvider, MotMemoryAuthStateProvider>(true, options => {
    options.IsSandbox = true; // Configurable sandbox for the Vehicle Enquiry
});
services.AddDvlaClientCache<MyCacheProvider>(); // Optional provider to support lookup caching
services.AddDvlaClientTenants<MyTenantProvider>(); // Optional provider to support multiple tenants
