4.2 Handling APIs Response

Each API Call retrieves a tuple which contains three values (Code, An Object of the API's Return, ResponseFeedBack Instance)

• Code: A Number that represents API state. Codes Reference
• API's Return Object: An object class of the API's Return and its attributes can be accessed using dot notation.
• Response FeedBack: An object of ResponseFeedBack class which has the following attributes:
  • message: A human readable description of the Code
  • data: A dict represents the actual API's Response
  • status_code: Status code that has been returned from the API (2xx, 4xx, 5xx)
  • exception_error: In case an exception is raised (Based on this Codes), you can see the error using this attribute.

Successful API calls will return the following values:

• Code: One of the Following Codes
• API's Return Object: object (Depending on the API response)
• Response FeedBack: ResponseFeedBack Object with the following attributes:
  • message: A success message depending on the API (Example: Get Order API will return a message like "Successfully Retrieved Order: 1")
  • data: None
  • status_code: 2xx
  • exception_error: None

Example:

from paymob.accept import AcceptAPIClient

accept_api_client = AcceptAPIClient()
code, transaction, feedback = accept_api_client.get_transaction(
    transaction_id=112233
)

print(f"Code: {code}")
print(f"Transaction: {transaction}")
print(f"Transaction ID: {transaction.id}")
print(f"Feedback Message: {feedback.message}")
print(f"Feedback Data: {feedback.data}")
print(f"Feedback Status Code: {feedback.status_code}")
print(f"Feedback Exception Error: {feedback.exception_error}")

Output:

Code: 10
Transaction: Transaction No: 111859918
Transaction ID: 111859918
Feedback Message: Transaction: 111859918 Retrieved Successfully
Feedback Data: None
Feedback Status Code: 200
Feedback Exception Error: None

Unsuccessful API calls will return the following values:

• Code: One of the Following Codes
• API's Return Object: Example: Get Transaction API will return a Transaction instance (transaction.id, transaction.success, ..etc)
• Response FeedBack: ResponseFeedBack Object with the following attributes:
  • message: A failure message depending on exception occured (Example: "An Error Occurred During the Request")
  • data: API's response dict (response.json())
  • status_code: 4xx or 5xx
  • exception_error: Expecting value: line 1 column 1 (char 0)

Example:

from paymob.accept import AcceptAPIClient

accept_api_client = AcceptAPIClient()
code, transaction, feedback = accept_api_client.get_transaction(
    transaction_id=112233
)

print(f"Code: {code}")
print(f"Transaction: {transaction}")
print(f"Feedback Message: {feedback.message}")
print(f"Feedback Data: {feedback.data}")
print(f"Feedback Status Code: {feedback.status_code}")
print(f"Feedback Exception Error: {feedback.exception_error}")

Output:

Code: 22
Transaction: None
Feedback Message: Non 2xx Status Code Returned.
Feedback Data: {'detail': 'Not found.'}
Feedback Status Code: 404
Feedback Exception Error: 404 Client Error: Not Found for url: https://accept.paymob.com/api/acceptance/transactions/112233

5- Codes Reference

5.1 Success Codes

Variable	Code	Description
SUCCESS	10	API Called Successfully Without any Failures

5.2 Error Codes

Variable	Code	Description
JSON_DECODE_EXCEPTION	20	An Error Occurred While Parsing the Response into JSON
REQUEST_EXCEPTION	21	An Error Occurred During the Request
HTTP_EXCEPTION	22	Non 2xx Status Code Returned
UNHANDLED_EXCEPTION	23	Unhandled Exception

You can import these codes like the following:

from paymob.response_codes import (
    SUCCESS, 
    JSON_DECODE_EXCEPTION, 
    REQUEST_EXCEPTION, 
    HTTP_EXCEPTION, 
    UNHANDLED_EXCEPTION
)

6- Settings

You can customized some behaves of Paymob by adding the following settings in .env file.

- ACCEPT_APIS_TIMEOUT_SECONDES

Sets Timeout for API Calls (The connect timeout is the number of seconds Requests will wait for your client to establish a connection or read data with/from Paymob server)

Default value is 10

Example:

ACCEPT_APIS_TIMEOUT_SECONDES=20

- VALIDATE_API_RESPONSE (Not Added Yet)

Automatically validates the returned data of the APIs to ensure that there are no changed keys or data types
