What you'll build​

Build a Mistral AI chat completion integration using the ballerinax/mistral connector that invokes Mistral's chat completion API to answer a user question and logs the response. The integration uses an Automation entry point to trigger the operation manually or on a schedule.

Operations used:

  • Chat Completion : Sends a user message to the Mistral API and retrieves a generated response
