Verify API Credentials Before Testing
Tip: Always double-check youruserid,password, or regenerated API key in every request. A common issue is using expired or incorrect credentials, which results in authentication errors (e.g., status code901).
Leverage Delivery Reports for Debugging
Tip: Use the SMS Delivery Report API (e.g.,/SMSApi/report/status) to track message status in real-time. Check fields likeStatusandCauseto identify delivery issues.
Secure Your API Key
Tip: Store your API key securely (e.g., in environment variables) and never expose it in client-side code. Regenerate it via SMSApi/apikey/update if compromised.Check DLT Compliance for India
Tip: For Indian numbers, ensure your senderid and message content comply with TRAI’s DLT regulations. Test with a registered template to avoid rejections.
Use URL Encoding for Message Content
Tip: Encode yourExample:msgparameter using UTF-8 to handle special characters (e.g., &, %, #) correctly. For example, in PHP, useurlencode("Your message here")before sending.
$message = urlencode("Hello & Welcome!");
$url = "https://www.smsgatewaycenter.com/SMSApi/rest/send?userId=YourUsername&password=YourPassword&msg=$message";Test with a Single Number First
Tip: Before sending bulk SMS, test your API call with one mobile number to confirm your setup works. Use the quick send method for quick validation.Example:curl -X GET "https://unify.smsgateway.center/SMSApi/send?userid=YourUsername&password=YourPassword&senderid=SMSGAT&mobile=919999999999&msg=Test+Message&output=json"
Handle JSON Responses Gracefully
Tip: Always parse theExample:statusandstatusCodefields in the JSON response to detect success or failure. Log thereasonfield for detailed error insights.
$response = json_decode($api_response, true);
if ($response['status'] === 'success' && $response['statusCode'] === '900') {
echo "SMS sent successfully!";
} else {
echo "Error: " . $response['reason'];
}Optimize Bulk SMS with JSON Format
Tip: For sending to multiple recipients, use the JSON-based API to batch messages efficiently. This reduces API calls and improves performance.Example:
curl -X POST \
https://unify.smsgateway.center/SMSApi/send \
-H 'Content-Type: application/json' \
-d '{
"userid": "YourUsername",
"password" : "XXXXX",
"senderid": "SENDER",
"msgType": "text",
"dltEntityId": "xxxxxxxxxxxxx",
"dltTemplateId": "xxxxxxxxxxxxx",
"duplicatecheck": "true",
"sendMethod": "quick"
"sms": [
{
"mobile": ["9999999991"],
"msg": "hello world again"
},
{
"mobile": ["9999999999"],
"msg": "Final last msg"
}
]
}'
Schedule Messages with Proper Time Formatting
Tip: When scheduling SMS, ensure theExample:scheduletimeparameter follows theYYYY-MM-DD HH:MM:SSformat (24-hour). Test with a future time to confirm it queues correctly.
