FetchAPI

FetchAPI brings the familiar web Fetch pattern to Unreal Engine. Fire a request, chain the response handling, and use built-in helpers for URLs, query strings and status codes - from Blueprints or C++.

If you have ever written fetch() in JavaScript, you already know this plugin: create a request, set method, headers and body, fire it, and handle the response object that comes back - status code, headers and JSON body all accessible as Blueprint values. Status-code classification helpers and URL encode/decode nodes remove the boilerplate that usually accumulates around HTTP code.

Use it for the same jobs the web Fetch API excels at: calling JSON APIs, posting form data, downloading configuration, wiring up webhooks and web services during rapid prototyping. Web developers moving to Unreal become productive immediately, and the broad platform allowlist means the same graphs ship everywhere.

FetchAPI is part of the Alpha XP networking collection for Unreal Engine 4.27-5.0+. Every feature is exposed to both Blueprints and C++, ships with styled HTML documentation, and follows one consistent API style across the whole collection. The plugin is compiled and verified against a clean UE 4.27 project, comes with a utility node pack (hashing, GUIDs, timestamps, tokens, validation), and is maintained under the Alpha XP brand with documentation hosted online.

Key Features:

- Fetch-style request/response flow

- URL encode/decode and query-string builder nodes

- Status-code classification helpers

- JSON-friendly request and response objects

- Broad platform support including mobile and console

- Utility node pack: CRC32/MD5/SHA-1 hashing, GUIDs, timestamps, random tokens and hostname validation
