This topic describes how to install Security Token Service (STS) SDK for Go and provides an example on how to use STS SDK for Go.

Background information

  • Alibaba Cloud provides OpenAPI Explorer to simplify API usage. You can use OpenAPI Explorer to debug API operations and dynamically generate SDK sample code.
  • For more information about STS API operations, see What is STS?.
  • For more information about STS endpoints, see Endpoints.

Install the SDK for Go

You can download the installation packages of the SDK for Go from the following links:


The following sample code provides an example on how to call the AssumeRole operation by using the SDK for Go. For other operations, you can use OpenAPI Explorer to debug the operations and obtain sample code.

package main

import (

func main() {
    // Create an Alibaba Cloud client that is used to initiate requests. 
    // Specify the AccessKey ID and AccessKey secret of the requester. The requester can be a RAM user or a RAM role. 
    client, err := sts.NewClientWithAccessKey("cn-hangzhou", "<AccessKeyId>", "<AccessKeySecret>")
    // Construct a request. 
    request := sts.CreateAssumeRoleRequest()
    request.Scheme = "https"
    // Specify request parameters. For more information about the parameters, see API Reference. 
    request.RoleArn = "<RoleArn>"
    request.RoleSessionName = "<RoleSessionName>"
    // Initiate the request and obtain a response. 
    response, err := client.AssumeRole(request)
    if err != nil {
    fmt.Printf("response is %#v\n", response)
