I am not sure what you are asking.
Do you want to call the API to add a new event to a calendar?
I think you just need to figure the parameters you need to pass and call the right API URL.
Keep in mind that once you get the access token, you do not need to call the API when the user is accessing your site. The user is just needed to authorize the access and later to authorize again if the token is revoked.
