Interactive Avatar in Arabic
Hey Heygen team and community,
Subject: Assistance Needed with HeyGen API to Generate Video Using Uploaded Image and Audio
Dear HeyGen Support Team,My name is Carlos, and I’m developing an iOS app in SwiftUI (Xcode 16.0+, iOS 14+) that integrates with the HeyGen API to generate talking avatar videos, replicating the workflow of the HeyGen web portal (https://app.heygen.com/home, phone and video section). My goal is to allow users to upload an image and audio via the app’s UI, pass these to the HeyGen API, and generate a video with a custom avatar and voice, but I’m encountering issues with the API integration. I’d appreciate your guidance to ensure my app matches the portal’s functionality.

Currently, in the dashboard, clicking on a public template opens a modal window showing a preview of the template along with thumbnails for each scene. From what I understand, the data for this modal comes from the internal API (api2.heygen.com/v1/pacific/template.list2).
Custom Font size and font color via Template API
For templates via API, is it possible to customise font-size and font-color? At the moment only content can be changed. I saw a post from a year ago that complicated parameters were not in the plan. Could you please advise if that's still the case?

How could i add the pauses?
Hi, im using Avatar IV Video to generate videos where my hero is reading the text (usually ask the questions).
I need to make a small pause before the starting (like one second) and sometimes i need to make the same short pauses (1-1.5 seconds) between sentences. Is it possible?
