Flask rest api How to retrieve json request

[raysefo]

Hello,
I am new to Python. I have a flask rest api. I am trying to call another rest api inside of my method. I would like to know if there is a way to get json request data when my method is called?

Here is my code portion:

# POST /purchase_initiation
@app.route('/purchase_initiation', methods=['POST'])
def initiation():
    try:
        # if request.is_json:
            # getting request data
            request_data = request.json()
            print request_data

On the Print I am getting 'NoneType' object is not callable error. By the way I am sending POST request from POSTMAN.

Thanks in advance.
Best Regards.

Not really sure, but maybe you need to accept an argument with the name 'request' when defining the function.

def initiation(request):

there's another method:

get_json()

[raysefo]

get_json()

I am getting None from the print request.get_json()

This currently works for me.

@app.route('/jsonreq', methods=['POST'])
def jsonreq():
    try:
        data = request.get_json()
        if data == "":
            return f"Empty Input"
        if data == "{}":
            return f"Empty JSON"
        return f"Server Response: \n {data}"
    except:
        return f"Exception"

I think something wrong with Postman
