Implementing Salesforce Integrations on Lightning Platform

You can implement your Salesforce integrations or other client applications, on the Lightning Platform by creating a Salesforce AppExchange app.

1. Create a WebLink that passes the user session ID and the API server URL to an external site:
   https://www.your_tool.com/test.jsp?sessionid={!API_Session_ID}&url={!API_Partner_Server_URL_80}

   Use https to ensure that your session ID cannot be detected.

2. The page pointed to in the preceding step takes the session ID and uses it to call back to the API. Use getUserInfo() to return the userID associated with the session and related information. If needed, you can also use retrieve on the User object to retrieve any additional information you need about the user.
3. Maintain a cross-reference between the UserId or username and the corresponding user ID in your system, which you can do using a WebLink that is executed when the user clicks a tab, or a WebLink on the page layout.
4. Package and upload this app using the instructions in Salesforce Help topic “Prepare Your Apps for Distribution.”
