Analyze a Typeform feedback submission and post its text and score to Mattermost only when the score is negative.

## Setup

Connect **Completed Typeform response** to Typeform and set your form ID. Select a secret Variable containing a Google Cloud API key on the **Analyze feedback sentiment** authentication input. Enable the Cloud Natural Language API and billing in that key’s Google Cloud project, and restrict the key to that API. The key is sent in the `x-goog-api-key` header.

For n8n, choose a Typeform credential and form in **Typeform Trigger**, and a Google Cloud Natural Language OAuth2 credential in **Google Cloud Natural Language**. The n8n trigger keeps the full submission so the question definitions and answers can be matched by field ID.

Use a text question titled **What did you think about the event?**. Select a Mattermost account and channel on **Alert Mattermost**. In n8n, select that account and channel on **Mattermost**.

## Behavior

A score below zero posts one message containing the feedback and score to Mattermost. Zero and positive scores return the analyzed feedback without sending a message.

Each completed form runs one sentiment analysis step against Google Cloud Natural Language v1, using plain text, automatic language detection, and UTF-16 sentence offsets. Blank answers, ambiguous question titles, or an invalid service response stop the run before a destination write. No workflow-level retries or delivery deduplication are configured. A later failed write can leave an earlier write completed; inspect the destination before rerunning the same submission.

Feedback text is sent to Google for sentiment analysis. Negative feedback is sent to the chosen Mattermost channel.

## Changes to the source

*   Replace the original private form and destination identifiers with configuration placeholders.
*   Match full Typeform answers to question definitions by field ID and reject missing or ambiguous required text answers. Leading or trailing whitespace in question titles is ignored.
*   Make the original numeric threshold explicit and validate the service’s score before choosing a branch.
*   Use a secret Google API key in Open Flow; the n8n version keeps its native Google OAuth2 credential. Both call the same v1 sentiment endpoint.
