[Feature Request] Implement direct_send_reaction (Emoji Reactions) for Direct Messages

[Ahmedxsaad]

Surprised to find that there is no working method to "react" (double-tap/emoji heart) to a Direct Message item in v2.2.1.

I have tried:

direct_answer (sends a reply text, works).
private_request to direct_v2/threads/{id}/items/{item_id}/send_reaction/ (Returns 404).
private_request to direct_v2/threads/{id}/items/{item_id}/like/ (Returns 404).

Goal:
To send a reaction to a specific message ID .

Environment:
instagrapi 2.2.1
Login method: Session ID / Password

Request: Please add support for the send_reaction endpoint or document the correct private endpoint structure

This looks like a valid missing feature, but not one I want to guess blindly.

Current instagrapi can parse direct-message reactions on read, but there is no implemented send API for message reactions yet. I also checked adjacent codebases we maintain for comparison, and there is no existing direct-message reaction sender there that could be cleanly ported here.

The endpoint guesses in the issue returning 404 are a strong sign that we need fresh app/HAR logs for the current mobile flow instead of guessing URL shapes.

I am leaving this open, but the next useful step is to capture a real Instagram app reaction flow and extract:

• the exact endpoint
• required payload fields
• headers / client context requirements
• whether the same flow is used for heart vs arbitrary emoji reactions

Once we have that, this should be implementable as a narrow direct mixin addition.
