I am getting errors in my code. Please Help me, I am trying to hit the given api in the code.

msgid = 123
obj = f"{"inline_keyboard": [[{"text": "Rename","callback_data": "/rename_link_start {msgid}"}]]}"
obj2 = urllib.parse.quote_plus(obj)
hit = requests.get(f"https://api.telegram.org/bot{token}/sendMessage?chat_id={id}&text=streaam&reply_markup={obj}"

Error:

If you have a look at the docs for the API you are using: https://core.telegram.org/bots/api#sendmessage

...you can see that the reply_markup field is "a JSON-serialized object".

So don't bother struggling against the problems of escaping quote marks and f-string variable delimiters ({ } which are also used by dictionary literals)

Just use Python's json module to serialize a JSON object, as specified in the API docs.

Also, you do not need to use an f-string to output querystring params for the GET request, the requests lib can do that for you also. See https://requests.readthedocs.io/en/latest/user/quickstart/#passing-parameters-in-urls

import json

msgid = 123
obj = {
  "inline_keyboard": [
    [{"text": "Rename", "callback_data": f"/rename_link_start {msgid}"}]
  ]
}
params = {
  "chat_id": id,
  "text": "streaam",
  "reply_markup": json.dumps(obj)
}
hit = requests.get(f"https://api.telegram.org/bot{token}/sendMessage", params=params)

Use simple quote ' when wrapping around double quote ''

The { and } has special meaning inside the f-string. So change it with double braces({{}}) wherever you don't need to use variables. Here's how to write it for eg:

msgid = "1"
print(f'{{"inline_keyboard": [[{{"text": "Rename", "callback_data": "/rename_link_start {msgid}"}}]]}}')

This will output

{"inline_keyboard": [[{"text": "Rename", "callback_data": "/rename_link_start 1"}]]}

As said by @Sparkling Marcel, you have to use single quotes ' inside double quotes "". If you use double quotes inside double quotes, python can not know where the strings begin and ends. Also, you can not use {} inside f-strings because braquets are reserved for string formatting. Instead of braquets you can use other types of string formatting such as % (see example below). In your particular code:

msgid = 123
obj = "{'inline_keyboard': [[{'text': 'Rename','callback_data': '/rename_link_start %s'}]]}" % msgid
obj2 = urllib.parse.quote_plus(obj)
hit = requests.get(f"https://api.telegram.org/bot{token}/sendMessage?chat_id={id}&text=streaam&reply_markup={obj}"
