API keys are essential for secure communication with SMSGatewayCenter’s Restful API, enabling you to send SMS programmatically. Here’s an overview of API keys and their usage:

What Are API Keys? #

  • API keys are unique codes used to authenticate and authorize requests to SMSGatewayCenter’s Restful API.
  • They act as login credentials, ensuring only authorized users can access the API for sending SMS.

How to Use API Keys on SMSGatewayCenter #

  • Include in Request Header: Add the API key to the request header for authentication when making API calls.
  • Use with UserID: Include your “userid” parameter along with the API key as login credentials in your API requests.
  • No Password Required: When using an API key, you don’t need to provide a password parameter, simplifying the authentication process.
  • Example Use Case:
  • To send an SMS via the API on May 17, 2025, at 03:20 PM IST, your request might look like this:
    • Header: Authorization: Bearer your_api_key
    • Parameter: userid=your_userid

Best Practices #

  • Keep your API key confidential to prevent unauthorized access.
  • Store the API key securely in your application, avoiding hardcoding in source code.
