Token - Parameter used to authenticate with your endpoint
Address - URL address of your endpoint
Name - Name format for your screenshots

Endpoint Configuration

For your endpoint to interact properly with this plugin it requires the following functionality:

Accept Content-Type: application/json over POST request method
Return JSON formatted response
- For success: {"href": "http://example.com/<screenshot>"}
- For error: {"error": "<Error> happened"}
