[shreyasingaraju]

Describe the task that needs to be done.
Set up endpoint and documentation for adding a buddy by communicating with 'Users'.

Set up empty endpoint methods with descriptions for adding a buddy that will show up on swagger.

Path: /api/pairing/
Request: Current User ID and added buddy's User ID.
Operation: PUT
Response: 200 OK. Adds new buddy's User ID to current user's array of all buddies.

Notes

[f-fromont]

Would you be able to include examples of the endpoint details in the solution description?

For example,

Endpoint: addBuddy
path: /api/pairing/
Request: Contains array of course Id's
Response: 200 OK

If you have any questions about what the endpoint should look like for now, don't hesitate to reach out here or on the discord :)
