How to process data sent to the Flask server?

Question

Flask

My friend and I are writing a site and he sends data from his js node server to my Flask server. I don't know how to take this data and process it. I don't even know how to approach this. My server shows that there was a Post request:
127.0.0.1 - - [18/Feb/2021 12:43:27] "?[37mPOST /api/index.php HTTP/1.1?[0m" 200 -
On the Flask server in the developer tools indicates
Status Code: 405 METHOD NOT ALLOWED

Everything I wrote the route that listens to:

from flask import Flask

app = Flask(__name__)

@app.route('/')
@app.route('/status')
def index():
    return 'ok'


@app.route('/api/index.php', methods=['POST'])
def listen():
    return "ok"


if __name__ == '__main__':
    app.run()

I'm just starting out and just want to understand how to work with it.
Thank you very much for your time.

All data is stored in request.

from flask import request

@app.route('/api/index.php', methods=['POST'])
def listen():
    # json данные
    print(request.json)

    # данные формы
    print(request.form.to_dict())

    # заголовки
    print(dict(request.headers))

    # аргументы
    print(request.args)

    return "ok"
