🔍 : Currently HeyGen’s API allows template generation using pre-defined variables (text, image, avatars, audio, etc.), but process is static—each run must fully specify all content.

✅ : Enable support for dynamic runtime variables that pull from the user’s profile or external data source—e.g. {{first_name}}, {{company_logo}}, {{custom_avatar}}—without rebuilding the template.

For instance:

– Automatically personalize videos by inserting each user’s name, avatar, profile picture, or unique voice preset.

– Streamline workflows for large-scale workflows (e.g. personalized onboarding, marketing outreach, custom greetings).

🎯 :

– Reduces friction and repetitive variable configuration for high-volume users.

– Allows API templates to scale with personalization (e.g. each recipient gets their own name/avatar).

– Speeds up dynamic video creation pipelines by decoupling variable binding from template design.

Would love to vote and support this if you’re planning to build dynamic templating features into the API—thanks!
