CreateOpenIDConnectProvider - AWS Identity and Access Management


Creates an IAM entity to describe an identity provider (IdP) that supports OpenID Connect (OIDC).

The OIDC provider that you create with this operation can be used as a principal in a role's trust policy. Such a policy establishes a trust relationship between AWS and the OIDC provider.

When you create the IAM OIDC provider, you specify the following:

  • The URL of the OIDC identity provider (IdP) to trust

  • A list of client IDs (also known as audiences) that identify the application or applications that are allowed to authenticate using the OIDC provider

  • A list of thumbprints of one or more server certificates that the IdP uses

You get all of this information from the OIDC IdP that you want to use to access AWS.


The trust for the OIDC provider is derived from the IAM provider that this operation creates. Therefore, it is best to limit access to the CreateOpenIDConnectProvider operation to highly privileged users.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.


A list of client IDs (also known as audiences). When a mobile or web app registers with an OpenID Connect provider, they establish a value that identifies the application. (This is the value that's sent as the client_id parameter on OAuth requests.)

You can register multiple client IDs with the same provider. For example, you might have multiple applications that use the same OIDC provider. You cannot register more than 100 client IDs with a single IAM OIDC provider.

There is no defined format for a client ID. The CreateOpenIDConnectProviderRequest operation accepts client IDs up to 255 characters long.

Type: Array of strings

Length Constraints: Minimum length of 1. Maximum length of 255.

Required: No


A list of server certificate thumbprints for the OpenID Connect (OIDC) identity provider's server certificates. Typically this list includes only one entry. However, IAM lets you have up to five thumbprints for an OIDC provider. This lets you maintain multiple thumbprints if the identity provider is rotating certificates.

The server certificate thumbprint is the hex-encoded SHA-1 hash value of the X.509 certificate used by the domain where the OpenID Connect provider makes its keys available. It is always a 40-character string.

You must provide at least one thumbprint when creating an IAM OIDC provider. For example, assume that the OIDC provider is and the provider stores its keys at In that case, the thumbprint string would be the hex-encoded SHA-1 hash value of the certificate used by

For more information about obtaining the OIDC provider's thumbprint, see Obtaining the Thumbprint for an OpenID Connect Provider in the IAM User Guide.

Type: Array of strings

Length Constraints: Fixed length of 40.

Required: Yes


The URL of the identity provider. The URL must begin with https:// and should correspond to the iss claim in the provider's OpenID Connect ID tokens. Per the OIDC standard, path components are allowed but query parameters are not. Typically the URL consists of only a hostname, like or

You cannot register the same provider multiple times in a single AWS account. If you try to submit a URL that has already been used for an OpenID Connect provider in the AWS account, you will get an error.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 255.

Required: Yes

Response Elements

The following element is returned by the service.


The Amazon Resource Name (ARN) of the new IAM OpenID Connect provider that is created. For more information, see OpenIDConnectProviderListEntry.

Type: String

Length Constraints: Minimum length of 20. Maximum length of 2048.


For information about the errors that are common to all actions, see Common Errors.


The request was rejected because it attempted to create a resource that already exists.

HTTP Status Code: 409


The request was rejected because an invalid or out-of-range value was supplied for an input parameter.

HTTP Status Code: 400


The request was rejected because it attempted to create resources beyond the current AWS account limits. The error message describes the limit exceeded.

HTTP Status Code: 409


The request processing has failed because of an unknown error, exception or failure.

HTTP Status Code: 500
