Twitter Webhook Verification Handler

This n8n workflow is designed specifically for handling verification requests from Twitter's Account Activity API. When registering a webhook, Twitter sends a CRC (Challenge Response Check) challenge, requiring your server to compute an HMAC SHA256 signature using your API Key Secret and return it in a JSON response. The workflow listens via a Webhook node, processes the incoming crc_token with the Crypto node for HMAC generation, and formats the response using a Set node before sending it back.

Benefits include seamless integration without custom coding, ensuring your webhook passes Twitter's security checks instantly. It's lightweight with only three nodes, making it fast and reliable for production use. This saves developers hours of boilerplate server setup.

Use cases: Essential for Twitter bots monitoring mentions, DMs, or events; real-time notifications for social media management tools; or integrating Twitter into larger n8n automations like CRM updates or analytics pipelines. Simply paste the webhook URL into Twitter's dashboard, add your API secret, and deploy.

For advanced setups, extend this workflow by adding nodes after verification to process actual Twitter events like tweets or follows.
