Add logging_client_events

Notes

This request is not associated with any specifific function This is a periodical request of instagram app at any version which contains a bunch of logs of users interaction with the app and a validation code. I’ve looked on github many instagram apis and so far nobody was able (or interested) in reverse engineer it. I do have a little suspect that it can be related to other problems i’ve in my project. Does anyoe have the skills to reverse it?

i’m pasting here a sample request of what im talking about

To maybe solve this issue, the channel “regular” has no qs token. You can just send your events there. A simple implementation in python since, i am not that good in typescript.

import base64
import zlib
import requests

def logging_client_events(message_dict):
    data = {
        "format": "json",
        "access_token": constants.APP_ID + "|" + constants.ACCESS_TOKEN,
        "sent_time": self.api.get_client_time(),
        "system_uptime": self.get_system_uptime(),
        "compressed": "1",
        "messsage": base64.b64encode(zlib.compress(bytes(json.dumps(message_dict).encode()), 1)).decode()
    }

    log_request = self.session.post("https://graph.instagram.com/logging_client_events", data=data)

    return log_request

So i think its pretty much solved, now all you have todo is to add logging_client_events in each api_call, that has a event involved for example “ig_main_feed_request_succeeded” etc.

@bolds07 no, no repo yet. Currently have few examples collected, probably it’ll help to collect more

Edit: this repo looks interesting, though: https://github.com/DamianoMagrini/instaverse/blob/857273e475a868585c91c07f626cbba5553ccb73/reversed-api/src/instagram/9568347_events.ts

This is for the web api.
