An alternative method of starting a session is to create a web form where your customers can enter short session key strings to start sessions with you.
To create a session key entry form, create a web form with the action of https://support.example.com/api/start_session and a method of either GET or POST. You must also use a text box with the name of short_key, as shown in the example below.
You may also include an external key to start a session.
Using this form, your customer can enter a generated seven-character session key and an optional external key to start a session with you.
