How to make the most of your HeyGen forum experience

General

Hello! I'm experiencing an issue with file uploads through the HeyGen API. Despite having a Pro subscription, when I try to upload an image or audio file, I get the error "asset data must be provided".

- **Endpoint:** https://upload.heygen.com/v1/asset

- **Headers:** X-Api-Key, Content-Type: multipart/form-data

1. Different endpoints (api.heygen.com/v1/asset, upload.heygen.com/v1/asset)

2. Different headers (X-Api-Key, Authorization: Bearer)

3. Different field names (file, image, asset, data, photo, upload)

4. Different data formats (FormData with Blob, FormData with Buffer, Base64 JSON)

5. Different file types (JPEG, PNG, WAV, MP3)

All attempts return a 400 BAD REQUEST error with the message:

{"code":40001,"message":"asset data must be provided"}

1. Are additional permissions required for uploading user files with a Pro subscription?

2. Am I using the API correctly for file uploads?

3. Are there any restrictions or requirements I'm not considering?

4. Can you provide a working example of file upload?

I need to create videos with custom avatars (from uploaded photos) and custom voices (from uploaded audio) for a Telegram bot.

- The API key works for fetching voice and avatar lists

- The issue only occurs when uploading files

- I'm using Node.js with the form-data library
