![]() ![]() This applies not only to global and environment variables, but collection and local variables as well. So why is it that we need to JSON-serialize our data some of the time, and not all the time?Īs mentioned above, primitive types such as strings and numbers do not need to be serialized only complex data types like arrays and objects will need serialization when saving them in variables. When you should serialize your data in Postman Once you receive that JSON data, your application will need to convert that string back into a structure that it can interact with in a more natural way. This allows the sending system to transport data to your client software in a way that is a high-level, abstracted form of their data. ![]() The most common way that APIs will “package” their data right now is by using JavaScript Object Notation, or JSON, and sending it as a big string within the HTTP response body. In fact, most APIs are already serializing data for us. If you need to store data in a more complex way-such as an array, or a deeply nested object-then transporting that data from one place to another is more easily managed between systems if we serialize the data. These primitive data types include strings, numbers, boolean true/false, and then “unknown” types such as “undefined” or “null” values. Most programming languages will interpret simple data types, sometimes called “primitives,” in a straightforward way. A string is given to the deserializer and turned back into a complex data type In this example, we’re still using JavaScript, and calling JSON.parse(). When we “deserialize” this data back into an array, we are reversing the process to convert a string into what our programming language will interpret as an array of simple integer types. When we serialize this data into a string, in this JavaScript example with JSON.stringify(), we can see how it is converted into a string that includes square brackets around our comma-delimited list of numbers: let arrayOfNumbers = A variable is given to the serializer and turned into a stringĪ simple example is an array of numbers. By turning these complex data structures into simpler types, it allows independent systems to convert data in ways that are agreed upon. It is especially useful when sharing data between multiple systems which may not all share common data types. “Serializing” data is used to store and convert complex data types when writing and reading from memory. ![]() Let’s do a quick review of serialization and why it’s used, and then look into Postman a little deeper. I have a background in development, specifically systems architecture, and so understanding how things communicate is something that greatly enhances my learning. When I examined the data in the Postman Console, it appeared that they were being stored in a JSON object, yet I was unable to access the values correctly on subsequent requests.įor viewers of my Postman Blindfold Challenge, we all learned that I love to peel back the layers on what’s really going on inside a system. I started livestreaming my journey on Twitch, and early on I was curious why I needed to serialize data in memory variables to pass between requests, especially when building dynamic request bodies. This challenge is a wonderful walk-through of the Postman API Platform’s main features, and it really helps you get familiarized with the many ways Postman is able to assist with your productivity.
