In this chapter, you learned how to build a RESTful API from scratch with Lambda and API Gateway. We also covered how to debug and troubleshoot incoming API Gateway requests by enabling the CloudWatch logs feature, plus how to create an API deployment stage and how to create multiple endpoints with different HTTP methods. Finally, we learned about the cold/warm container issue and why Lambda functions should be stateless.
In the upcoming chapter, we will use DynamoDB as a database to manage data persistency for our API.
