SDK 3.0 is a companion tool for the TencentCloud API 3.0 platform. You can use all SMS APIs through the SDK. The new SDK version is unified and features the same SDK usage, API call methods, error codes, and returned packet formats for different programming languages.
Note:
API version required for connecting to Tencent Cloud International:
SMS API v2021-01-11 is required. For details, see the sample code.
SMS sending APIs:
One message can be sent to up to 200 numbers at a time.
Signature and body template APIs:
Individual users have no permission to use signature and body template APIs and can manage SMS signatures and SMS body templates only in the SMS console. To use the APIs, change "Individual Identity" to "Organizational Identity".

Prerequisites

You have learned about the concept of region and selected a region as needed.
You have activated SMS. For detailed directions, please see Getting Started.
You have obtained the SecretID and SecretKey on the API Key Management page in the CAM console.
SecretID is used to identify the API caller.
SecretKey is used to encrypt the string to sign that can be verified on the server. You should keep it private and avoid disclosure.
The endpoint of the SMS service is sms.tencentcloudapi.com.

Relevant Documents

For more information on the APIs and their parameters, please see API Documentation.
You can download the SDK source code from Github Repository.

Sample Code

Note:
All samples are for reference only and cannot be directly compiled and executed. You need to modify them based on your actual needs. You can also use API 3.0 Explorer to automatically generate the demo code as needed.
Each API has a corresponding request structure and a response structure. This document only lists the sample code of several common features as shown below:
