 """ This is an API made to remove a single instance of training data. This is useful in cases where a single instance of content has been modified, but the remaining examples remain valid. For example, if a piece of content has been retagged. Inputs data - String: The exact text you wish to remove from the given collection. If the string provided does not match a known piece of text then this will fail. Again, this is required if an id is not provided, and vice-versa. api_key (optional) - String: Your API key, required only if the key has not been declared elsewhere. This allows the API to recognize a request as yours and automatically route it to the appropriate destination. cloud (optional) - String: Your private cloud domain, required only if the key has not been declared elsewhere. This allows the API to recognize a request as yours and automatically route it to the appropriate destination. """
