Every API request requires your userId and projectId. Here’s where to find them.

​
User ID

The userId uniquely identifies your Streampixel account. It never changes — save it once and reuse across every API call.
1

Open the dashboard

Sign in at dashboard.streampixel.io.
2

Open your account menu

Click your account name in the top-right corner.
3

Copy the User ID

Click Copy User ID. The value is now on your clipboard.

​
Project ID

Each project has its own projectId. You’ll need it for project-scoped calls like uploading a build or distributing a file.
1

Open the project

From the dashboard, navigate to the project’s detail page.
2

Copy the Project ID

Click the Project ID button.
You can also read it from the URL: 
https://dashboard.streampixel.io/projectdetail/67944b8a3f323be4b89a2272
                                               └─────── projectId ───────┘
Mismatched IDs cause 401 Invalid User or 404 Project not found. Double-check that the userId matches the account that owns projectId.

​
Using both in a request

Both IDs go in the JSON request body alongside your API key: 
{
  "apiKey": "your-api-key",
  "userId": "663d0a1b2c3e4f5a6b7c8d9e",
  "projectId": "67944b8a3f323be4b89a2272",
  "fileUrl": "https://storage.example.com/build.zip"
}
