Answers to common questions related to APIs, API management, and Apigee Edge

API stands for Application Programming Interface and is a set of protocols and tools for building software applications
APIs are popular because they allow different software systems to communicate and share data with each other
API management involves the process of creating, publishing, documenting, and analyzing APIs
Apigee Edge is an API management tool that provides features such as security, analytics, and developer portal
REST stands for Representational State Transfer and is a type of web architecture used for creating APIs
SOAP and REST are two different types of APIs, with SOAP being more complex and REST being more lightweight
API proxy is a server-side component that acts as an intermediary between the client and the backend service
Base path is the URL path that is used to access the API proxy, and is important for routing requests to the correct backend service
Proxy endpoint is the endpoint that the client sends requests to, while target endpoint is the endpoint that the proxy sends requests to
Virtual host is a hostname that is used to access the API proxy, and can be specified in the API proxy configuration
OpenAPI Specification is a standard for describing REST APIs, and can be used to generate API proxies in Apigee Edge
HTTP methods such as GET, POST, PUT, and DELETE are frequently used in Apigee Edge for interacting with APIs
OAuth 2.0 is a protocol for authorization and authentication, with grant types such as authorization code, implicit, and client credentials
Rate-limiting policies such as Spike Arrest and Quota can be used to restrict the number of API calls made to Apigee Edge
Spike Arrest policy limits the number of requests per second, while Quota policy limits the number of requests per time period
Concurrent rate limit policy limits the number of requests that can be processed simultaneously
Calendar Quota type is used to limit the number of requests per calendar month or year
Route rule is used to route requests to different backend services based on certain criteria
API orchestration involves the process of combining multiple APIs to create a more complex API
Service callout is a policy that allows the proxy to call an external service and use the response in the API flow
Hosted targets are used to route requests to backend services that are hosted outside of Apigee Edge
Conditional flow is used to execute different policies based on certain conditions
Custom error messages can be created using the Raise Fault policy
Shared flow is a reusable set of policies that can be used across multiple API proxies
KVM stands for Key-Value Map and is used to store and retrieve key-value pairs in Apigee Edge
Assign message policy is used to modify the message content or headers in the API flow
API access can be restricted based on client IP address using the IP filter policy
Post client flow is a flow that is executed after the response is sent to the client
Named target servers can be created and used for routing requests based on API environment
