Issue while fetching data from Spotify API. Getting Response 500

[divishasunny]

Hello,

I am new to Spotify API and I am trying to get the data of recently played tracks using python. I created 2 files. One is main.py and I wanted to test if I am recieving any response from the API and I created test.py for testing. The code present in main.py is as follows:

import json

from dotenv import load_dotenv

import os

import base64

from requests import post

load_dotenv()

client_id = os.getenv("CLIENT_ID")

client_secret = os.getenv("CLIENT_SECRET")

#print(client_id, client_secret)

def get_token():

    auth_string = client_id + ":" + client_secret

    auth_bytes = auth_string.encode("utf-8")

    auth_base64 = str(base64.b64encode(auth_bytes), "utf-8")

    url = "https://accounts.spotify.com/api/token"

    headers = {

        "Authorization": "Basic " + auth_base64,

        "Content-Type": "application/x-www-form-urlencoded"

    }

    data = {

        "grant_type": "client_credentials",

        "scope": "user-read-recently-played"

    }

    result = post(url, headers=headers, data=data)

    json_result = json.loads(result.content)

    token = json_result["access_token"]

    return token

token = get_token()

#print(token)

and the code in test.py is as follows:

import pandas as pd

import requests

from datetime import datetime

import datetime

from main import get_token

#USER_ID = "YOUR_USER_ID"

TOKEN = get_token()

input_variables = {

    "Accept" : "application/json",

    "Content-Type" : "application/json",

    "Authorization" : "Bearer {token}".format(token=TOKEN)

}

today = datetime.datetime.now()

yesterday = today - datetime.timedelta(days=1) #no of Days u want the data for)

yesterday_unix_timestamp = int(yesterday.timestamp()) * 1000

# Download all songs you've listened to "after yesterday", which means in the last 24 hours      

r = requests.get("https://api.spotify.com/v1/me/player/recently-played?limit=50&after={time}".format(time=yesterday_unix_timestamp), headers=input_variables)

data = r.json()

print(r)

whenever I run test.py, I keep getting <Response[500]> and not able to fetch the data. I would be glad if someone can help me with this issue.

An indication  of your problem is 'grant_type': 'client_credentials'

Since the Client Credentials flow does not include authorization, only endpoints that do not access user information can be accessed. Therefore, in this case, you should use a different Authorization method that lets you log in.

Can you please suggest the authorization method I can use I am very new to using APIs and cannot understand what to use.

I prefer the Authorization Code flow. Here is a stack overflow answer with  code by someone else: https://stackoverflow.com/a/75292843/7111585
