The values that correspond to the `ACCOUNT_SID`, `AUTH_TOKEN`, and `FROM` parameters are required to connect to Twilio, but these are generally configured in the **Instant messaging** section on the **General** tab in the Configuration Panel. However, if they've been configured in the SENDMESSAGE action in the process, these values will override any corresponding values set in the Configuration Panel. ## Parameters ### Required parameters
