## IamAssumeAuthenticator class

The IamAssumeAuthenticator obtains an IAM access token using the IAM "get-token" operation's "assume" grant type. The authenticator obtains an initial IAM access token from a user-supplied apikey, then exchanges this initial IAM access token for another IAM access token that has "assumed the identity" of the specified trusted profile.

The bearer token will be sent as an Authorization header in the form:

Authorization: Bearer &lt;<!-- -->bearer-token<!-- -->&gt;

**Signature:**

```typescript
export declare class IamAssumeAuthenticator extends IamRequestBasedAuthenticatorImmutable 
```
**Extends:** IamRequestBasedAuthenticatorImmutable
