Automatically generate personalized welcome videos

We operate an e-commerce/member management system built on OpenCart. Goal: When a member signs up on our website, we aim to automatically generate personalized welcome/onboarding videos for them and deliver these videos via channels such as WhatsApp and email. Video Dynamism (Personalization Requirement): We have a pre-recorded standard video template (featuring the speaker). We require that the introductory part of the message, Dear [Member Name], be automatically personalized using the name fetched from our OpenCart database. This personalization should be done both vocally (via Text-to-Speech) and/or visually (as on-screen text).

What would be the most efficient way to implement this automation within OpenCart? If anyone has experience with similar personalized video workflows or can recommend tools, extensions, or an integration approach, I’d greatly appreciate your guidance. Thank you in advance!

Use n8n to trigger on new OpenCart member signups via webhook or API poll. Fetch member name from OpenCart, then use a video generation service like Synthesia, Heygen, or D-ID to create personalized videos with TTS and text overlays.

Alternatively, use Remotion or Creatomate for template-based video rendering with dynamic text. Once generated, send via WhatsApp Business API and email through n8n nodes.

Set up OpenCart webhook for new registrations, pass data to n8n, generate video, store in cloud storage, then deliver links. Most efficient for scale and automation.
