API stands for “application programming interface.” An API is essentially a set of rules that dictate how two machines talk to each other.
Some examples of API-based interactions include a cloud application communicating with a server, servers pinging each other, or applications interacting with an operating system.
Is Swagger free to use
The Swagger specification and all public tools under the swagger-api GitHub account are free to use and licensed under the Apache 2.0 License.
What is a callback API
A callback is an asynchronous API request that originates from the API server and is sent to the client in response to an earlier request sent by that client.
APIs can use callbacks to signal an event of interest and share data related to that event.
How do I send an API key
A CARTO API Key is physically a token/code of 12+ random alphanumeric characters. You can pass in the API Key to our APIs either by using the HTTP Basic authentication header or by sending an api_key parameter via the query string or request body.
If you use our client library CARTO.
What is the difference between API and Lambda
API calls are made from various external apps; they are processed by Api gateway, and are routed to Lambda for processing.
Lambda may use other AWS services to complete a request, and, once complete, it sends back the response to the external app via API gateway.
When Should API gateway be used
You need an API gateway because it provides a unified entry point across internal APIs.
It allows you to control user access. And it enables security measures, like rate limiting, and applies security policies, like OAuth or JWT.
An API gateway is especially important for securing microservices.
Can we use Lambda without API gateway
Looks like an ability to directly call Lambdas over the Internet without an API Gateway was just added to the SDK.
Function urls are available using the Lambda API and are supported in CloudFormation, AWS SAM and AWS CDK.
How do I add API key to API gateway?
- Choose a REST API
- In the API Gateway main navigation pane, choose Resources
- Under Resources, create a new method or choose an existing one
- Choose Method Request
- Under the Settings section, choose true for API Key Required
- Select the checkmark icon to save the settings
Do you need both load balancer and API gateway
There must be a load balancer for the API gateway that can adapt to changes in microservices, such as versioning and dynamic scaling.
Additionally, the API gateway should have separate access controls for direct and indirect customers in addition to ensuring secure transportation and verification of data in transit.
How do I create a REST API key?
- In the web app, navigate to User Icon My Profile User Settings
- In the section API Access, click Create API User Token
- Enter a Description to help you identify the key later
- Click Create Key
Is Lambda suitable for REST API
We have used AWS Lambda quite successfully with reasonable and acceptable response times. (REST/JSON based API + AWS Lambda + Dynamo DB Access).
The latency that we measured always had the least amount of time spent in invoking functions and large amount of time in application logic.
How do I use API key to call API gateway
Sign in to the API Gateway console. Choose an existing API or create a new one.
In the primary navigation pane, choose Settings under the chosen or newly created API.
Under the API Key Source section in the Settings pane, choose HEADER or AUTHORIZER from the drop-down list.
How do I setup an API gateway?
- Open the API Gateway console
- Choose Create API
- Under HTTP API, choose Build
- Choose Add integration, and then choose an AWS Lambda function or enter an HTTP endpoint
- For Name, enter a name for your API
- Choose Review and create
- Choose Create
What are endpoints in API
An API endpoint is a point at which an API — the code that allows two software programs to communicate with each other — connects with the software program.
APIs work by sending requests for information from a web application or web server and receiving a response.
How do I authenticate API keys
Basic Authentication You can pass the API key via Basic Auth as either the username or password.
Most implementations pair the API key with a blank value for the unused field (username or password).
You will need to base64-encode the ‘username:password’ content, but most request libraries do this for you.
What are AWS step functions
AWS Step Functions is a low-code, visual workflow service that developers use to build distributed applications, automate IT and business processes, and build data and machine learning pipelines using AWS services.
What is the difference between OpenAPI and Swagger
Although the terms once referred to the same thing, they can no longer be used interchangeably…even though some people still do.
In 2021, OpenAPI refers to the industry-standard specification for RESTful API design. Swagger refers to a set of SmartBear tools.
Is Swagger a framework
Practically, it’s a language-agnostic tool that gets everyone on the same page. Swagger (okay, now the “Open API Initiative” more on that later!) is a framework for describing your API using a common language that everyone can understand.
How Swagger JSON is generated?
- Navigate to your Swagger docs endpoint
- Open the browser console
- Refresh the page
- Navigate to the network tab and filter by XHR requests
- Right click on the XHR request that ends in ? format=openapi
- You can now just copy and paste that into a new JSON file!
Is Swagger a testing tool
Swagger UI is the best tool for programmers, testers, and end-users to know the benchmarks they are testing.
It offers information regarding the service with the created OpenAPI requirement.
What is the difference between Swagger and Swagger UI
Swagger Editor: Swagger Editor lets you edit OpenAPI specifications in YAML inside your browser and to preview documentations in real time.
Swagger UI: Swagger UI is a collection of HTML, Javascript, and CSS assets that dynamically generate beautiful documentation from an OAS-compliant API.
What does Swagger most popular for
The OpenAPI Initiative was created to guide the development of the OAS in an open and transparent manner.
Swagger has since become the most popular suite of tools to fully leverage the power of the OAS across the API lifecycle.
What is Swagger vs Postman
Swagger is an API specification & Postman is an API Client and appropriate for API first development while, Postman is appropriate for testing such API based on specifications.
What does GB Second mean
GB-seconds are the number of seconds your function runs for, multiplied by the amount of RAM memory consumed.
It’s a computed metrics, calculated multiplying two other metrics, and it’s a reasonable way to measure how many resources your serverless functions consume, in relation to time and memory.
What is MWS
Mowat-Wilson syndrome (MWS) is a rare genetic disorder that may be apparent at birth or later in childhood.
