n8n Workflow: Analyze Typeform Feedback with Google Cloud Natural Language and Send Mattermost Message

This n8n workflow automates the process of analyzing feedback submitted via Typeform using Google Cloud Natural Language and then sending a notification to Mattermost based on the sentiment of the feedback.

What it does

This workflow simplifies and automates the following steps:

1. Triggers on New Typeform Submission: It listens for new form submissions from a configured Typeform.
2. Analyzes Sentiment with Google Cloud Natural Language: It takes the submitted text feedback and sends it to Google Cloud Natural Language for sentiment analysis.
3. Routes Based on Sentiment Score: It checks the sentiment score returned by Google Cloud Natural Language.
   • If the sentiment score is above a certain threshold (indicating positive feedback), it proceeds to the next step.
   • If the sentiment score is below the threshold (indicating neutral or negative feedback), it takes no further action in the Mattermost branch.
4. Sends Message to Mattermost: If the feedback is determined to be positive, it sends a message to a specified Mattermost channel or user, including details from the Typeform submission.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running instance of n8n.
• Typeform Account: An active Typeform account with a form configured to collect feedback.
• Google Cloud Project with Natural Language API Enabled: A Google Cloud project with the Natural Language API enabled and appropriate credentials (e.g., Service Account Key or OAuth 2.0).
• Mattermost Account: An active Mattermost account with access to a channel or user for sending messages.

Setup/Usage

1. Import the Workflow:

   • Download the workflow JSON.
   • In your n8n instance, go to "Workflows" and click "New".
   • Click the three dots in the top right corner and select "Import from JSON".
   • Paste the workflow JSON or upload the file.

2. Configure Credentials:

   • Typeform Trigger:
     • Click on the "Typeform Trigger" node.
     • Add or select your Typeform API credentials.
     • Select the specific Typeform you want to monitor.
   • Google Cloud Natural Language:
     • Click on the "Google Cloud Natural Language" node.
     • Add or select your Google Cloud credentials (e.g., Service Account Key).
     • Ensure the Natural Language API is enabled in your Google Cloud project.
   • Mattermost:
     • Click on the "Mattermost" node.
     • Add or select your Mattermost API credentials.
     • Configure the "Channel" or "User" where you want the messages to be sent.
     • Customize the message content to include relevant Typeform submission data.

3. Configure the "If" Node:

   • Click on the "If" node.
   • Set up the condition to evaluate the sentiment score from the "Google Cloud Natural Language" node. For example, you might check if {{ $json.sentiment.score > 0.5 }} to filter for strongly positive feedback. Adjust the threshold as needed.

4. Activate the Workflow:

   • Once all credentials and configurations are set, activate the workflow by toggling the "Active" switch in the top right corner of the workflow editor.

Now, whenever a new submission is made to your configured Typeform, the workflow will automatically analyze its sentiment and, if positive, send a notification to Mattermost.
