Simon Signal is our event protocol and the event processing pipe that powers it. Using this onsite method you can send us data then use that data to trigger downstream events.

You have two options to ingest with Simon Signal:

  • A JS Pixel you can install directly on your site, via Google Tag Manager, or via Tealium (for web developers using Javascript)
  • Use the Simon Signal HTTP API to send data upstream directly via our endpoint (for server-side developers or if you're using a language other than Javascript)


Simon Signal JS Pixel vs. Webhooks

  • Sending real-time events data from a website or mobile app to Simon? Use Simon Signal JS Pixel.

  • Sending real-time events data from another system (, SendGrid,etc)? Use webhooks.
