Example Usage

from netgsm import Netgsm

netgsm = Netgsm(
    username="YOUR_USERNAME",
    password="YOUR_PASSWORD",
    appname="YOUR_APP_NAME"  # Optional
)

# Send SMS
response = netgsm.sms.send(
    msgheader="HEADER",
    messages=[

            "msg": "Hello world!",
            "no": "5XXXXXXXXX"
        }
    ]
)

print(response)

Using Environment Variables (.env)

In the examples that come with the SDK, user credentials are read from the .env file. To run the example applications, create a .env file in the project root directory and add the following information:

NETGSM_USERNAME=YOUR_USERNAME
NETGSM_PASSWORD=YOUR_PASSWORD
NETGSM_MSGHEADER=YOUR_SMS_HEADER
NETGSM_APPNAME=YOUR_APP_NAME

You can start by copying the .env.example file:

cp .env.example .env

Then update the .env file with your own information.

Error Handling

The SDK provides an advanced error handling mechanism to manage various error conditions that the Netgsm API may return.

Error Types

from netgsm.exceptions.api_exception import (
    ApiException,           # Base API exception class
    HttpException,          # Base class for HTTP errors
    BadRequestException,    # HTTP 400 errors
    UnauthorizedException,  # HTTP 401 errors
    ForbiddenException,     # HTTP 403 errors
    NotFoundException,      # HTTP 404 errors
    NotAcceptableException, # HTTP 406 errors (Netgsm errors usually return this way)
    TimeoutException,       # Timeout errors
    ConnectionException,    # Connection errors
    ServerException         # HTTP 5XX server errors
)

Example Usage

from netgsm import Netgsm
from netgsm.exceptions.api_exception import ApiException, NotAcceptableException

# Initialize Netgsm client
netgsm = Netgsm(username="user", password="pass")

try:
    # Send SMS
    response = netgsm.sms.send(
        msgheader="HEADER",
        messages=[
            {
                "msg": "Test message",
                "no": "5XXXXXXXXX"
            }
        ]
    )
    print(f"SMS sent. JobID: {response.get('jobid')}")
except NotAcceptableException as e:
    # Error returned by Netgsm
    print(f"Netgsm error: {e.message}")
    print(f"HTTP status: {e.http_status}")
    print(f"Error code: {e.code}")
except ApiException as e:
    # General API error
    print(f"API error: {e.message}")

HTTP Status Codes

• HTTP 200 (OK): Operation successful
• HTTP 406 (Not Acceptable): Netgsm API errors (e.g., invalid JobID, invalid header)

Netgsm API Error Codes

The Netgsm API may return the following error codes with HTTP 406 status code:

The SDK automatically recognizes these error codes and includes the relevant description in the NotAcceptableException. If the error code is not found in the table above, it is reported as "Undefined error code".

Error Codes Example

For an example of how to catch and handle different error codes, see the Error Codes Example.

try:
    response = netgsm.sms.send(...)
except NotAcceptableException as e:
    if e.code == "40":
        print("Message header is not defined!")
    elif e.code == "30":
        print("Invalid credentials or no API access!")
    else:
        print(f"Netgsm error: {e.message}")
