You may need to generate an access key or an API token to use in your APIs to call a VMware Cloud service. Generate an Access KeyGenerate an access key if you want to make an authorized call to the APIs of any of the VMware Cloud services on behalf of all your organizations. Access keys work best with the API of the cloud service platform. An access key is not time-limited, but can be revoked and regenerated. Generate API TokensYou use API tokens to authorize actions per organization. Previously referred to as OAuth Refresh tokens, an API token handles authorization more securely than an access key because it authorizes access per organization, and not across all your organizations. Use an API token to access the APIs of the cloud services platform and the VMware Cloud services.
