You also have to give the Authorizer Permission to invoke Lambda. Required fields are marked *. Your Lambda function is now created. Lets see another example. To use parameter mapping, you specify API request or response parameters to modify, and specify how to modify those parameters. Thanks for letting us know this page needs work. Stage variables are defined on the Stage level, and they are not related to any input, unlike query string parameters, which are temporary for every query. Note: If theres more than one HTTP method configured for the API, repeat steps two through 10 for each method. The prod Stage Editor page appears, displaying the Invoke URL. Then, add a new query string with the desired method request parameter mapping expression. To deploy V1 of the API, create a simple Lambda function and expose that through API Gateway: Finally, review the settings in the next page and choose Create function.
