The content of the string is a JSON- or YAML-formatted service template. For example: + +"template": { + "tosca_definitions_version": "tosca_simple_yaml_1_0", + ... +} +This parameter is required only when you omit the template_url parameter. If you specify both parameters, this value overrides thetemplate_url parameter value. + +template_url (Optional) string A URI to the location containing the service template on which to perform the operation.
