Typeform Feedback Sentiment Alert to Mattermost

Typeform Feedback Sentiment Alert to Mattermost

This workflow automatically monitors new Typeform submissions, analyzes the sentiment of the feedback using AWS Comprehend, and sends an urgent notification to a Mattermost channel whenever a negative response is detected. It helps support and product teams instantly react to unhappy users without manual monitoring.

How It Works

• Typeform Trigger (OAuth2) — Listens for new form submissions on a specific Typeform form. When a submission occurs, it passes the entire response to the next node.
• AWS Comprehend (IAM API Key auth) — Takes the feedback text from the submission and runs sentiment analysis. Returns a sentiment score and label (e.g., NEGATIVE, POSITIVE, NEUTRAL).
• IF (No auth) — Checks if the detected sentiment equals "NEGATIVE". If yes, execution goes to the Mattermost node; otherwise it goes to a NoOp node that does nothing.
• Mattermost (API Token auth) — Composes a message containing the negative sentiment score and the original feedback text, then posts it to the specified Mattermost channel.
• NoOp (No auth) — A placeholder for the false branch so the workflow completes cleanly when sentiment is not negative.

Setup Instructions

1. Typeform: Create a Typeform account and design a form with a question like "What did you think about the event?" (must match the field name in the workflow). In n8n, connect to Typeform using OAuth2 – you'll need to create an app in your Typeform developer settings.
2. AWS Comprehend: You need an AWS account with IAM credentials (Access Key ID and Secret Access Key) that have permission to call the DetectSentiment API. In n8n, create an AWS credential with those keys.
3. Mattermost: You need a Mattermost server or cloud instance, plus an API token (personal access token) with permission to post to a channel. Obtain the Channel ID (e.g., h7cxrd1cefr13x689enzyw7xhc). In n8n, create a Mattermost credential with the server URL and token.
4. Update the form ID in the Typeform Trigger node: replace DuJHGW5 with your actual form ID.
5. Update the Mattermost channel ID in the Mattermost node.
6. Optional: Adjust the IF condition if you want to alert on a different sentiment (e.g., POSITIVE or NEUTRAL).

Use Cases & Variations

• Customer Support: Immediately alert your support team when a user leaves negative feedback after an event or purchase.
• Product Feedback: Route negative product reviews to a #bugs channel while leaving positive ones untouched.
• Multi-langauge: The workflow works with any langauge supported by AWS Comprehend (English, Spanish, French, etc.).
• Extentions: You can replace Mattermost with Slack (using the Slack node) or add an email notification via SMTP. You could also log all responses to a Google Sheet for historial analysis.
