Upload File API

📘Introduction

The Upload File API allows you to upload a packaged Unreal Engine build (as a .zip) to your Streampixel project. This API is used by power users, automation tools, or our official Unreal Plugin to deploy new builds to the cloud.

📦 Use Case: Uploading a Build via URL

The Upload File API is designed for developers who want to create a custom pipeline where they:

1. Build their Unreal Engine project

2. Package it into a .zip file

3. Upload that .zip to their own cloud storage

4. Send the public download link to Streampixel via this API

This workflow allows full flexibility and can be used in CI/CD tools, internal build systems, or automated release pipelines.

☁️ You’ll Need Your Own Cloud Storage

To use this API, you must host the .zip file yourself — for example, on:

• AWS S3 (with a signed or public URL)

• Google Cloud Storage

• DigitalOcean Spaces

• Any HTTP-accessible file server

---

⚠️ Important: File Must Be Directly Downloadable

We expect that the moment Streampixel accesses the fileUrl, the download should begin automatically.

This means:

• No login pages

• No redirect delays

• No HTML wrappers

• No download buttons

✅ Valid example: https://your-bucket.s3.amazonaws.com/MyBuild.zip

❌ Invalid example: https://drive.google.com/file/d/abc123/view

✅ Pre-requisites

✅ What Happens After Upload

Once your request is successfully processed:

1. The build is sent to our internal Build Manager Server for downloading and validation.

2. The system verifies:

   • That the .zip file is accessible and properly structured

   • That it contains the required binaries

3. If the build passes validation, it will be distributed to our servers and linked to your project.

📺 How to Confirm It's Working

You can confirm that your build has been successfully linked by:

• Logging in to your Streampixel Dashboard

• Navigating to your project’s detail page

• Refreshing the page

If everything went well, you’ll see your uploaded build listed there and processing
