How can I use the Webflow API Key to upload a media file in CURL format into the assets folder?

To upload a media file into the assets folder using the Webflow API Key in CURL format, you can follow the steps outlined below:

1. Obtain your Webflow API Key: First, you need to generate an API Key in your Webflow account. Navigate to your Project Settings, then click on the "API" tab. Generate a new API Key or use an existing one.

2. Construct the CURL command: Open your preferred terminal or command-line interface and construct the CURL command using the following template:

```
curl -F "files=@/path/to/your/file.jpg" -H "Authorization: Bearer {YOUR_API_KEY}" https://api.webflow.com/{API_VERSION}/sites/{SITE_ID}/assets
```

Replace the following placeholders with your actual values:
- `/path/to/your/file.jpg`: The local path to the file you want to upload (e.g., `/Users/username/Desktop/file.jpg`).
- `{YOUR_API_KEY}`: Your unique Webflow API Key.
- `{API_VERSION}`: The version of the Webflow API you are using (e.g., `1.0.0` or `2.0.0`).
- `{SITE_ID}`: The unique identifier of your Webflow site.

3. Execute the CURL command: Once you have constructed the command with the correct values, execute it in your terminal. The CURL command will send an HTTP POST request to the Webflow API endpoint responsible for uploading assets.

4. Verify the upload: After executing the CURL command, you should receive a response from the Webflow API. If the upload was successful, the response will contain information about the uploaded asset, including its file name, size, and URL. You can also check your Webflow project's Assets panel to verify that the file has been successfully uploaded.

It's worth noting that the Webflow API is a powerful tool that allows you to perform various operations, including creating collections, updating content, and more. Make sure to refer to the Webflow API documentation for complete details on available endpoints and their specific usage.
