How to make a Post request to an API using Google Colab

Question

I need to make the following POST request using Google Colab:

POST https://http.msging.net/commands HTTP/1.1
Content-Type: application/json 
Authorization: Key YOUR_TOKEN 

{ 
"id": "a456-42665544000-0123e4567-e89b-12d3", 
"to": "[email protected]", 
"method": "get", 
"uri": "lime://wa.gw.msging.net/accounts/+55115555555" 
}

I have tried:

import requests
import re

YOUR_TOKEN = "mytoken"

data = { 
"id": "a456-42665544000-0123e4567-e89b-12d3", 
"to": "[email protected]", 
"method": "get", 
"uri": "lime://wa.gw.msging.net/accounts/+55115555555" 
}

headers = {
  "Content-Type": "application/json", 
  "Authorization": YOUR_TOKEN 
}
response = requests.post('https://http.msging.net/commands', headers=headers, data=data)

print(response)

For which I get:

<Response [400]>

I also tried:

import requests
import re

YOUR_TOKEN = "Key cHJvY29ycG9lc3RldGljYWF2YW5jYWRhMTg6cEFBSXFuYTZOR1FFWnpydFltTlo="

data = { 
"id": "a456-42665544000-0123e4567-e89b-12d3", 
"to": "[email protected]", 
"method": "get", 
"uri": "lime://wa.gw.msging.net/accounts/+55115555555" 
}

headers = {
  "Content-Type": "application/json", 
  "Authorization": YOUR_TOKEN 
}
response = requests.post('https://http.msging.net/commands HTTP/1.1', headers=headers, data=data)

print(response)

For which I get:

<Response [404]>

How do I get this request using Google Colab?

Here is the documentation, it does not provide examples. Just the requests.

Answer 1

You get a 400 Bad Request error, as - although you set the Content-Type header to application/json - you do not send JSON-encoded data.

As per Python requests documentation, when sending JSON data, you need to either use the data parameter and pass a JSON-encoded string, as well as manually set the Content-Type header to application/json:

payload = {'some': 'data'}
r = requests.post(url, data=json.dumps(payload), headers={"Content-Type": "application/json"})

or, if you don't want to encode the dict yourself, use the json parameter, and Python requests will automatically encode it for you, as well as set the Content-Type header to application/json:

r = requests.post(url, json=payload)

You would still need to add your TOKEN key to the Authorization header, as you already do.
