Alibaba Cloud Credentials for PHP is a tool that helps PHP developers manage their credentials.


Your system needs to meet Prerequisites, including PHP> = 5.6. We strongly recommend using the cURL extension and compiling cURL 7.16.2+ using the TLS backend.


If you have Globally Install Composer on your system, install Alibaba Cloud Credentials for PHP as a dependency by running the following directly in the project directory:

composer require alibabacloud/credentials

Some users may not be able to install due to network problems, you can switch to the Alibaba Cloud Composer Mirror.

See Installation for details on installing through Composer and other means.

Quick Examples

Before you begin, you need to sign up for an Alibaba Cloud account and retrieve your Credentials.

Credential Type


Setup access_key credential through [User Information Management][ak], it have full authority over the account, please keep it safe. Sometimes for security reasons, you cannot hand over a primary account AccessKey with full access to the developer of a project. You may create a sub-account [RAM Sub-account][ram] , grant its [authorization][permissions],and use the AccessKey of RAM Sub-account.


use AlibabaCloud\Credentials\Credential;

// Chain Provider if no Parameter
$credential = new Credential();

// Access Key
$ak = new Credential([
    'type'              => 'access_key',
    'access_key_id'     => '<access_key_id>',
    'access_key_secret' => '<access_key_secret>',


Create a temporary security credential by applying Temporary Security Credentials (TSC) through the Security Token Service (STS).


use AlibabaCloud\Credentials\Credential;

$sts = new Credential([
    'type'             => 'sts',
    'access_key_id'    => '<access_key_id>',
    'accessKey_secret' => '<accessKey_secret>',
    'security_token'   => '<security_token>',


By specifying [RAM Role][RAM Role], the credential will be able to automatically request maintenance of STS Token. If you want to limit the permissions([How to make a policy][policy]) of STS Token, you can assign value for Policy.


use AlibabaCloud\Credentials\Credential;

$ramRoleArn = new Credential([
    'type'              => 'ram_role_arn',
    'access_key_id'     => '<access_key_id>',
    'access_key_secret' => '<access_key_secret>',
    'role_arn'          => '<role_arn>',
    'role_session_name' => '<role_session_name>',
    'policy'            => '',


By specifying the role name, the credential will be able to automatically request maintenance of STS Token.


use AlibabaCloud\Credentials\Credential;

$ecsRamRole = new Credential([
    'type'      => 'ecs_ram_role',
    'role_name' => '<role_name>',
// Note: `role_name` is optional. It will be retrieved automatically if not set. It is highly recommended to set it up to reduce requests.

Bearer Token

If credential is required by the Cloud Call Centre (CCC), please apply for Bearer Token maintenance by yourself.


use AlibabaCloud\Credentials\Credential;

$bearerToken = new Credential([
    'type'         => 'bearer',
    'bearer_token' => '<bearer_token>',

Default credential provider chain

The default credential provider chain looks for available credentials, looking in the following order:

1. Environmental certificate

The program first looks for environment credentials in the environment variable. If the ALIBABA_CLOUD_ACCESS_KEY_ID and ALIBABA_CLOUD_ACCESS_KEY_SECRET environment variables are defined and not empty, the program will use them to create default credentials.

2. Configuration file

If the user's home directory has the default file ~/.alibabacloud/credentials (Windows is C:\Users\USER_NAME\.alibabacloud\credentials), the program will automatically create credentials with the specified type and name. The default file may not exist, but parsing errors will throw an exception. The voucher name is not case sensitive. If the voucher has the same name, the latter will overwrite the former. This configuration file can be shared between different projects and tools, and it will not be accidentally submitted to version control because it is outside the project. Environment variables can be referenced to the home directory %UserProfile% on Windows. Unix-like systems can use the environment variable $HOME or ~ (tilde). The path to the default file can be modified by defining the ALIBABA_CLOUD_CREDENTIALS_FILE environment variable.

type = access_key                  # Authentication method is access_key
access_key_id = foo                # Key
access_key_secret = bar            # Secret

type = ecs_ram_role                # Authentication method is ecs_ram_role
role_name = EcsRamRoleTest         # Role name, optional. It will be retrieved automatically if not set. It is highly recommended to set it up to reduce requests.

type = ram_role_arn                # Authentication method is ram_role_arn
access_key_id = foo
access_key_secret = bar
role_arn = role_arn
role_session_name = session_name

3. Instance RAM role

If the environment variable ALIBABA_CLOUD_ECS_METADATA is defined and not empty, the program will take the value of the environment variable as the role name and request to get the temporary Security credentials are used as default credentials.

Custom credential provider chain

You can replace the default order of the program chain by customizing the program chain, or you can write the closure to the provider.


use AlibabaCloud\Credentials\Providers\ChainProvider;
