Hi Rakesh,
Could you confirm if what you are creating via the AdWords API are Gmail ads or HTML ads? The supported Gmail and HTML 5 ads can be found in this
guide.
Additionally, the "OperationAccessDenied.OPERATION_NOT_PERMITTED_FOR_CAMPAIGN_TYPE" error you are encountering indicates that you are using a mutate operation on a campaign type that is not supported in the AdWords API. However, so I can confirm this and so that I can better investigate, could you send to me the complete SOAP request and response logs that was generated when the error occurred?
You may send your reply using the

Thanks and regards,
