Bug Report: Sending Voice Messages via broadcastVoice Endpoint No Longer Supported

Summary:
Attempting to send voice messages using the broadcastVoice method results in a 400 Bad Request error with the message:
This feature is no longer supported.

---

Environment:

• Instagram Private API library version: [1.46.1]
• Bun.js version: [1.2.9]
• Operating System: [e.g., Windows 11]

---

Description:

When trying to send a voice message in a direct thread using the broadcastVoice method, the Instagram API responds with an error indicating that the feature is no longer supported. The upload process completes successfully, but the final request to share the voice message fails.

---

Steps to Reproduce:

1. Prepare an ACC to MP4 audio file using ffmpeg
2. Upload the MP4 file as a voice message with the required metadata.
3. Call broadcastVoice to send the voice message in a direct thread.
4. Observe the API response returning a 400 error with message: This feature is no longer supported.

---

Expected Behavior:

The voice message should be delivered successfully in the direct thread.

---

Actual Behavior:

Instagram API rejects the request with the following error:

POST /api/v1/direct_v2/threads/broadcast/share_voice/ - 400 Bad Request; This feature is no longer supported.

---

Workaround:

Currently, sending the audio as a regular video message (using broadcastVideo) appears to work as a fallback.

---

Additional Notes:

• This seems to be a change on Instagram’s side, deprecating or removing the /share_voice/ endpoint.
• Please confirm if there is a new supported method for sending voice messages or if this feature has been permanently disabled.
• Any guidance or updates on this issue would be appreciated.
