aws advanced api gateway

API Gateway has many advanced usage patterns.

Importing APIs into API Gateway

• Importing API Definition Files
  • You can use the API Gateway Import API feature to import an API using
  a definition file
• Supported protocols
  • OpenAPI (Swagger) is supported
• Create new and update existing APIs
  • You can use an OpenAPI definition file to create a new API or update an existing
  API endpoint

Legacy protocols

API Gateway supports legacy API protocols like SOAP (Simple Object Access Protocol) that returns in XML format rather than JSON.

• API Gateway can be configured as a SOAP web service passthrough that will pass

the XML responses through the gateway

• You can also use API Gateway to transform the XML response into JSON

Exam tips

• You can import APIs using external definition files, ex: OpenAPI (Swagger)
• When using legacy applications you can configure API Gateway to handle XML

from SOAP responses either as passthrough or transforming to JSON
