Steps

  1. Confirm the app was authorized via the Authorization Code Flow, since the Implicit Flow does not issue refresh tokens at all
  2. Store the refresh_token returned alongside the original access_token from the initial code exchange
  3. Before or after the access token expires, POST to https://auth.accela.com/oauth2/token with the refresh_token to obtain a new access_token
  4. Update the app's stored access token with the new value and continue calling Construct API endpoints as normal
  5. If a refresh token itself becomes invalid, generate a new one via the Accela Admin Portal (or, on v4.4.9+, the Construct admin portal) per application and agency
