Getting started wih API

from fyers_apiv3 import fyersModel
import webbrowser

"""
In order to get started with Fyers API we would like you to do the following things first.
1. Checkout our API docs :   https://myapi.fyers.in/docsv3
2. Create an APP using our API dashboard :   https://myapi.fyers.in/dashboard/

Once you have created an APP you can start using the below SDK

#### Generate an authcode and then make a request to generate an accessToken (Login Flow)

1. Input parameters

redirect_uri= "APP REDIRECT URI"  ## redircet_uri you entered while creating APP.
client_id = "XCXXXXXxxM-100"                       ## Client_id here refers to APP_ID of the created app
secret_key = "MH*****TJ5"                          ## app_secret key which you got after creating the app 
grant_type = "authorization_code"                  ## The grant_type always has to be "authorization_code"

state = "sample"                                   ##  The state field here acts as a session manager. you will be sent with the state field after successfull generation of auth_code

1. Just by printing the variable name 
2. There is a library named as webbrowser which will then open the url for you without the hasel of copy pasting
both the methods are mentioned below"""

### After succesfull login the user can copy the generated auth_code over here and make the request to generate the accessToken 
auth_code = "Paste the auth_code generated from the first request"

response = appSession.generate_token()

## There can be two cases over here you can successfully get the acccessToken over the request or you might get some error over here. so to avoid that have this in try except block
try: 
    access_token = response["access_token"]
except Exception as e:
    print(e,response)  ## This will help you in debugging then and there itself like what was the error and also you would be able to see the value you got in response variable. instead of getting key_error for unsuccessfull response.



## Once you have generated accessToken now we can call multiple trading related or data related apis after that in order to do so we need to first initialize the fyerModel object with all the requried params.

fyerModel object takes following values as arguments
1. accessToken : this is the one which you received from above
