Provide URL functionality for pre-populated summary/description

I would like to integrate further into our JIRA Service desk and the idea of a pre-populated link to a specific request type would be ideal.

For example:

• User clicks on public link
• User redirected to request
• User notices that the summary and the description are already pre-popuated with contextual information

Implementation:

I suspect the most simple implementation would be URL parameters that pre-populate the summary/description.
Such as: https://<jira-base-url>/servicedesk/customer/portal/1/create/92?summary=Test&description=More%20Text%20for%20the%20description

The (better) alternative would be the ability to use headers but would be more complicated.

Use Case:

• Dynamically generated support links throughout applications (such as "Report a problem with this document" or "Request access to this page")

Thanks!
