What problem does it solve? AI coding agents hallucinate SDK signatures, model shapes, and error types when integrating the PayPal .NET SDK, producing code that fails to compile or misuses the API. This Skill provides an authoritative, generated SDK map so every operation signature, enum value, and error accessor is looked up rather than guessed. ## Core Features & Use Cases - SDK Identity & Setup: Provides the NuGet package name (AsadAli.Checkout.Sdk), root namespace (PayPalServerSdk), client/options classes, OAuth2 credential properties, and environment configuration. - Bundled SDK Map: Indexes all 40 operations across 5 controllers (Orders, Payments, Subscriptions, TransactionSearch, Vault) with exact C# signatures, must-pass-explicitly parameters, return types, and per-operation error accessors, plus 286 record models and 85 enums with JSON wire names. - Error-Handling Guidance: Documents the two error cases (typed {Operation}Error vs RawError) with TryGet accessors and HTTP status mappings for each operation. - Use Case: A developer asks their agent to integrate PayPal order creation and capture in a .NET service; the agent loads this Skill, looks up CreateOrder and CaptureOrder signatures in the map, and writes compiling code with correct namespaces, named arguments, and typed error handling. ## Quick Start Ask your agent to integrate the PayPal .NET SDK into your project, for example to create and capture a checkout order, and it will load this Skill to ground every signature and model in the bundled SDK map.
