To successfully send email notifications with patient details to a healthcare provider when a new appointment is made in an EMR application, you have to complete the following prerequisite tasks.

1. Create an agent group

   You must create an agent group in Oracle Integration before you can run the connectivity agent installer. Creating the agent group automatically creates an OAuth client application in Oracle Identity Cloud Service. This enables the connectivity agent to use OAuth 2.0 token-based authentication when invoking Oracle Integration endpoints.

   To create an agent group, see Create an Agent Group in Using Integrations in Oracle Integration 3.

2. Download and install the connectivity agent.

   Download the connectivity agent installer to install the agent in your local environment. During installation, you associate the connectivity agent with the agent group identifier you generated when creating an agent group in Oracle Integration. Ensure that you restrict access to the folder in which you install the connectivity agent to only those users who need to stop and start the agent.

   To download and install the connectivity agent, see Agent Download and Installation in Using Integrations in Oracle Integration 3.

3. Install and use the HL7 Simulator.
   The HL7 Simulator is used to simulate the EMR application to send HL7 messages.
   1. Download and install the HL7 Simulator.
   2. Launch the HL7 Simulator application.
   3. From the top menu bar, select the Send/Receive icons. Message Receiver and Message Sender panes are visible at the bottom of the application window.

   4. In the Message Sender window, select the Setup Send.. icon. In the <hostname>:<port> field enter localhost: 22223.
      Message Sender simulates the EMR system to send HL7 V2.5.1 messages.
