AWS SDK Version 3 for .NET
API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Container for the parameters to the CreateOpenIDConnectProvider operation. 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 to establish a trust relationship between AWS and the OIDC provider.

When you create the IAM OIDC provider, you specify 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, and a list of thumbprints of the server certificate(s) that the IdP uses. You get all of this information from the OIDC IdP that you want to use for access to AWS.

Because trust for the OIDC provider is ultimately derived from the IAM provider that this action creates, it is a best practice to limit access to the CreateOpenIDConnectProvider action to highly-privileged users.

public class CreateOpenIDConnectProviderRequest : AmazonIdentityManagementServiceRequest

The CreateOpenIDConnectProviderRequest type exposes the following members



Public Property ClientIDList System.Collections.Generic.List<System.String>

Gets and sets the property ClientIDList.

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 action accepts client IDs up to 255 characters long.

Public Property ThumbprintList System.Collections.Generic.List<System.String>

Gets and sets the property ThumbprintList.

A list of server certificate thumbprints for the OpenID Connect (OIDC) identity provider's server certificate(s). 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, if the OIDC provider is and the provider stores its keys at "", 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.

Public Property Url System.String

Gets and sets the property Url.

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 host name, 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.


The following example defines a new OIDC provider in IAM with a client ID of my-application-id and pointing at the server with a URL of
