![]() This allows you to host scripts externally and reference these scripts in the exported collection. The script object in an event has an src object, which is a URL. Scripts in exported collections are wrapped in an event object, where each event has its own unique script. It also makes it easier to manage version control for the exported script. This enables you to not only define multiple pre-request and test scripts, but also enable or disable any one of them depending on your use case. In contrast, the collection format specification allows you to put multiple events in an event list, which is basically an array of events. In Postman, a collection or a request can only have one pre-request and test script pair. Much like collections in Postman, the collection format specification supports two types of events: pre-request events and test events. Scripting in Postman has a lot of advantages, and the collection format specification provides even more options and capabilities. They are instead included in the request headers. Cookies aren’t part of the request object in the collection format specification, which is why they aren’t represented as a unique object in the exported collection. When working with cookies in Postman, you can add them to your request headers using the cookie key. ![]() When you export a collection that uses a global or environment variable, the reference to that variable will be included, but the declaration of the variable won’t be included because it isn’t part of that collection. Global and environment variables, in contrast, are provided by the Postman client to enable developers to work across multiple scopes. This is because the collection format specification only supports collection variables, which are declared within the collection scope of your workbench in Postman. When a collection that makes use of a variable is exported, it’s important to note that only collection variable declarations will be included in the exported collection’s JSON. Variables in Postman Collections have different scopes, and the scope in which they are declared determines their precedence. These headers are included at request runtime and are never part of the exported collection’s JSON. If you hover over the Info icon next to one of these headers, you will see a brief description of that header’s purpose. When you navigate to the Headers section of your workbench, you will notice that some headers have already been added by default at Postman’s recommendation. Here is how you can work with the underlying collection format to get more out of your collections. The collection format specification defines the structure of Postman Collections that we know and love-providing all the information we need about a collection, including the requests, authorizations, HTTP headers, and even example responses to specific requests. In other words, this SDK provides JavaScript level object manipulation for the JSON structure defined by The collection schema outlines the JSON definition of data structure accepted by the constructor of each properties of log items at root level of the collectionĪfter loading the collection from file, one can do a lot more using the functions that are available in the SDK. M圜ollection = new Collection(JSON.parse(fs.readFileSync('sample-collection.json').toString())) ![]() Load a collection to memory from a JSON file on disk (say, sample-collection.json) var fs = require('fs'), // needed to read JSON file from diskĬollection = require('postman-collection').Collection, In this example snippet we will get started by loading a collection from a file and output the same in console. ![]() Installing from NPM, the following command installs the SDK and saves in your package.json > npm install postman-collection -save Postman Collection SDK can be installed using NPM or directly from the git repository within your NodeJS projects. Out issues before this goes into the Postman Apps. To know more about Postman Collections, visit theĬollection documentation section on Postman Website.īuilds a stronger foundation for improving your productivity while working with APIs. Like name and description too so that all the information that a developer needs to use your API is available easily. Requests can also store sample responses when saved in a collection. These requests can be further organized into folders toĪccurately mirror your API. Using this module aĭeveloper can create collections, manipulate them and then export them in a format that the Postman Apps and Postman CLIĪ collection lets you group individual requests together. Postman Collection SDK is a NodeJS module that allows a developer to work with Postman Collections.
