Is your feature request related to a problem? Please describe.

Societies want a way to give roles based on membership from another service. e.g. 'Community Membership' role when membership bought from Students Union website

Requirements

1. Create an API to let admins give a role based on an email address
2. Include rate limiting, authentication and other safety and privacy features
3. Create a template client to interact with the API using a given CSV (SVGE can be used as an example)
4. Create graphic for how data is transferred, and secured to provide to KoalaBot sponsors

Describe alternatives you've considered

Implement an API for requesting membership roles given

Example POST
curl POST 'https://api.koalabot.uk/joey/adv_verify?user_email=ab12c34@soton.ac.uk&user_email=def56g7@soton.ac.uk'
--header 'client-id: <DiscordServerID>'
--header 'Authorization: Bearer <Koala API Token>'
--header 'role_id: <MembershipRole>'

joey used as the name of the API in case a rework is needed and therefore the endpoint can be changed (similar to twitch API approach)
