Save and Activate the Scenario
After configuring Facebook Messenger, Caption AI, and any additional nodes, don’t forget to save the scenario and click "Deploy." Activating the scenario ensures it will run automatically whenever the trigger node receives input or a condition is met. By default, all newly created scenarios are deactivated.
Test the Scenario
Run the scenario by clicking “Run once” and triggering an event to check if the Facebook Messenger and Caption AI integration works as expected. Depending on your setup, data should flow between Facebook Messenger and Caption AI (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
Most powerful ways to connect Facebook Messenger and Caption AI
Facebook Messenger + Caption AI + Google Sheets: When a new message is received in Facebook Messenger, the text is sent to Caption AI. Sentiment analysis could be performed outside of Latenode. Then log key data from the message (e.g., timestamp, sender, message content) into Google Sheets for analysis.
Facebook Messenger + Caption AI + Slack: When a new message is received in Facebook Messenger, summarize the conversation using Caption AI. Then, post the summary and a link to the conversation in a dedicated Slack channel.
