The Chat with History process is called by an HTTP request using the User_Prompt, Path_To_File_With_History, and User_ID input parameters. When you invoke the process, it creates a file with history after your first question.
To invoke the Chat with History process, perform the following steps:
1Open the Chat with History process and click Actions > Properties Detail > Copy Service URL.
2Open a text editor and add the input fields and values to the service URL as shown in the following format:
<Cloud Application Integration POD URL>/active-bpel/public/rt/<API_name>?User_Prompt=<User_Prompt>&Path_To_File_With_History=<C:/folder>/&User_ID=<User_ID>
3Open a browser and paste the service URL.
The process creates or updates a file with the last question and LLM response. If no file exists or the file is empty, the process prepares a request without history. If the file has history, the process uses only the last question and response. The process then updates the file and appends the new question and answer.
