How to send a request?

Question

I need to send a request with the following data

"order": {
   "server_callback_url": "http://site.id/callback",
   "currency": "UAH",
   "amount": "1400",
   "order_type": "settlement",
   "response_url": "http://site.id/test/responsepage/",
   "order_id": "test1234561467462099.19",
   "operation_id": "test1234561467462099.19",
   "order_desc": "test order",
   "merchant_id": 700001,
   "receiver": [
     {
       "requisites": {
         "amount": 100,
         "merchant_id": 500001
       },
       "type": "merchant"
     },{
       "requisites": {
         "amount": 200,
         "merchant_id": 600001
       },
       "type": "merchant"
     },
  ]
}

I need to send them to https://api.fondy.eu/api/settlement

But I never did that. I am not familiar with DRF at all. Tell me how to implement it, please.

You could use DRF as the documentation : https://www.django-rest-framework.org/tutorial/2-requests-and-responses/

Or without DRF :

# importing the requests library 
import requests 

# api-endpoint 
URL = "https://api.fondy.eu/api/settlement"


# defining a params dict for the parameters to be sent to the API 
 data =
   "order": {
   "server_callback_url": "http://site.id/callback",
   "currency": "UAH",
   "amount": "1400",
   "order_type": "settlement",
   "response_url": "http://site.id/test/responsepage/",
   "order_id": "test1234561467462099.19",
   "operation_id": "test1234561467462099.19",
   "order_desc": "test order",
   "merchant_id": 700001,
   "receiver": [
     {
       "requisites": {
         "amount": 100,
         "merchant_id": 500001
       },
       "type": "merchant"
     },{
       "requisites": {
         "amount": 200,
         "merchant_id": 600001
       },
       "type": "merchant"
     },
  ]
}

# sending get request and saving the response as response object 
r = requests.POST(url = URL, data= data) 

# extracting data in json format 
data = r.json()

Maybe you would like to try the API before writing code, there is tool like postman to do this quickly :)

If we visit the endpoint, it says that only POST methods are allowed. We can make a POST request for example with the requests package.

import requests

data = {
  "order": {
     "server_callback_url": "http://site.id/callback",
     "currency": "UAH",
     "amount": "1400",
     "order_type": "settlement",
     "response_url": "http://site.id/test/responsepage/",
     "order_id": "test1234561467462099.19",
     "operation_id": "test1234561467462099.19",
     "order_desc": "test order",
     "merchant_id": 700001,
     "receiver": [
       {
         "requisites": {
         "amount": 100,
         "merchant_id": 500001
       },
       "type": "merchant"
     },{
       "requisites": {
           "amount": 200,
           "merchant_id": 600001
       },
       "type": "merchant"
     },
    ]
  }
}

headers = {'Content-type': 'application/json', 'Accept': 'text/plain'}
response = requests.post('https://api.fondy.eu/api/settlement', data=data, headers=headers)

The header can be important, since it tells you in what format you make your reqest, and some APIs do not work if you do not set the Content-type properly.

The response is here a Response object, and you can parse the response to a Python dictionary with:

response.json()

locally this gives me:

{'response': {'error_code': 1002,
              'error_message': 'Application error',
              'request_id': 'iUxQzJfyBuxdI'}}

The status code is 200, so that probably means that the callback you specified was not valid (or some other items in your request).

Thanks. And somehow you can understand what exactly gives error 1002? — unknown, May 15 '19 at 15:18
@ДмитрийДмитрук: well you will need to consult the documentation of the endpoint you trigger, since that depends on the application. — Willem Van Onsem, May 15 '19 at 15:19
Here is the documentation. Only she is in Russian, unfortunately ... https://docs.google.com/document/d/198d8Zbb7cgx-vAXAhNn_Oyhqc-fG1UXe4W0G-aQJzkE/edit# — unknown, May 15 '19 at 15:21
https://docs.fondy.eu/docs/page/21/ says that error 1002 is an unknown error and you should contact support. — dirkgroten, May 15 '19 at 15:56
