Generate random 16 bytes to use as IV var IV = CryptoJS. Now let’s see how to encrypt data using the crypto-js AES specification in the code below: var CryptoJS = require( "crypto-js") ![]() One of those packages is crypto-js which we’ll be using to encrypt data on the Pre-request Script. **As the name implies, it’s a script that runs just before a request is sent.Īlso, Postman is pre-installed with some popular JavaScript packages and these packages can be utilized in the Pre-request Script for manipulating data. So, I began another round of research and stumbled upon a tab on Postman called **Pre-request Script. The result - more efficient and less tedious work.Įven though I had experience with Postman, I didn’t know how to encrypt data before making a request yet. This is done by allowing users to create and save simple and complex HTTP/s requests, as well as read their responses. And the fastest way to test an API without creating a frontend is with Postman.Īccording to BlazeMeter, Postman is a popular API client that makes it easy for developers to create, share, test and document APIs. Once I discovered what I was looking for, I had to test my findings. Since I hadn’t done such a thing before, I had to do some research to see how this was done. The backend was written with Java, so I thought about how to accomplish this with Node.js. On the backend, the ciphertext is then decrypted back to plaintext. Recently, I started interacting with a project’s backend that accepts only encrypted dat - that is, plaintext is converted to ciphertext before it is sent to the backend. Prerequisite: Knowledge of JavaScript, Node.js, and basic knowledge of Postman Is WireMock a free service? WireMock is completely free under the Apache 2.0 license.LinkedIn logo for sharing a link Twitter logo for sharing a link Reddit logo for sharing a link If you’re looking for a hosted version of WireMock, check out WireMock Cloud. Is WireMock open source? Yes, WireMock is a completely open source API mocking tool ( GitHub repo). Finally, WireMock is easy to integrate into any workflow due to its numerous extension points and comprehensive APIs. Responses of any complexity can be dynamically generated via the Handlebars based templating system. What makes WireMock unique? WireMock has a rich matching system, allowing any part of an incoming request to be matched against complex and precise criteria. How do you create an API mock? WireMock supports several approaches for creating mock APIs - in code, via its REST API, as JSON files and by recording HTTP traffic proxied to another destination. It can also be used to rapidly prototype APIs that don’t exist yet. When do you need to mock APIs? API mocking is typically used during development and testing as it allows you to build your app without worrying about 3rd party APIs or sandboxes breaking. ![]() What is API mocking? API mocking involves creating a simple simulation of an API, accepting the same types of request and returning identically structured responses as the real thing, enabling fast and reliable development and testing. ![]() FAQ What is WireMock? WireMock is a free API mocking tool that can be run as a standalone server, or in a hosted version via the WireMock Cloud managed service.
