To begin interacting with the SentimentIt API, you must first have a Researcher account with a valid email and password. Sign in through the API to receive an authentication token. You must include your authentication token with all subsequent requests. Sign out to end your session.
Sessions are expired after 72 hours automatically. This allows you to make multiple requests over a 72 hour period without signing in again. If you wish to expire your session before the 72-hour period, sign out manually as documented above.
Detailed documentation for API requests can be found here.
