Postman now supports Web Sockets! Let’s see what we can do with Discord’s WebSocket Gateway.

Postman released the ability to communicate with servers using WebSockets. Diversifying the types of services it can connect to and taking a big step in interacting with event-driven architecture. WebSockets are for real-time communication(RTC) rather than a regular REST API endpoint.

REST APIs are great for updating and retrieving data from a database or interacting with services through forms or page elements. But WebSockets give you the ability to have chat apps and stream real-time data with the guarantees of the HTTP protocol.

Postman collection to connect two APIS and send a list of Dropbox folder members reminders to sign documents

Awhile back I was a guest on the Postman web stream along with Marcel Ribas from Dropbox. Our task was to build something live using the Dropbox and HelloSign APIs. So obviously, me being me, we set out to create a bot.

Dropbox acquired HelloSign but their products, and their APIs, are not integrated with each other yet, so the sky was the limit on what functionality we wanted to create.

I like to think about a high-level user perspective, so in…


Keep the S3 bucket private and place it behind a CDN while also routing the apex domain to a www subdomain

When you go to most websites you can probably notice two things, the site usually redirects to HTTPS and it usually redirects to the WWW subdomain. Whether you type in the naked domain (the apex domain) or not. The reasons to do so are long but mostly for SEO and professional expectations, here’s a shortlist of good reasons.

Another thing, I’ll point out that bugs me is when people use AWS S3 for hosting, which sets their S3 bucket to public. I know this is an offered feature but your one misconfiguration mishap from a hacker is defacing your site.


Push to S3 and invalidate Cloudfront with every merge

I am a sucker for CI/CD pipelines. I pretty much build those out before I build any other project, to be honest. Ever since Github came out with workflow and actions I have been all over it!

Instead of relying on some online rando’s actions, I went straight to the source. AWS created and support their own Github actions. AND on top of that, Github actually comes pre-installed with AWS CLI now.

I just wanted to simply update an S3 bucket and invalidate my Cloudfront for the bucket.

First, we configure our credentials using the Github Action provided by AWS…


Syncing Dropbox and Cloudinary using Postman

A single company can have many different versions of product snapshots across several organizations; customer support, sales, technical documentation, marketing, customer success, etc. This can break brand alignment. When everyone has their own copy of how to do something can be confusing to customers as they talk across organizations and ultimately lead to frustration.

At my current company, I wanted to synchronize the images and maintain them across organizations. The screenshots being used by customer support should also be the same ones used by technical documentation. …


Postman Monitors creating serverless Slack bots

In the 7 years of being a casual user of Postman, using it to lob requests to services I was building or trying to use, I never really dived into the features they released over the years.

Postman has an onslaught of features for prepping and testing APIs. They offer JS sandbox to run scripts before and after a request is made. They offer Monitors which is basically a cron job to run your collections in the cloud along with a dashboard. …


Kristen Stewart, Postman’s Event Manager, was looking for a fun way to give out swag (trust me I’m getting tired of that word too) at Postman’s sponsor booth for the AWS re:Invent Conference in Las Vegas. She wanted to do something interactive with the Postman app and went with the Vegas theme for AWS. She landed on a slot machine that could be triggered by the Postman app aka an API.

I volunteered to make it — the backend of it!

I wanted to make it all in AWS. …


The increasing popularity of Bitcoin and other cryptocurrencies has prompted countless people to ask me every day how and where they can get Bitcoin and other cryptocurrencies; so let me show you the simplest way to trade and obtain cryptocurrencies.

First of all, similar to visiting a foreign country, you have to exchange your native homeland’s currency for this digital currency. Welcome to Internet Country! You can do this at exchanges. Coinbase is one of the most simple, user-friendly exchanges.

1. Buy On Coinbase

If you are familiar with the stock market then Coinbase is the equivalent of the Robinhood app for the crypto…


I want to give a brief overview what Bitcoin is. Here’s a list of quick answers to some of the most common questions in the Bitcoin sphere:

“Bitcoin is just fake money”

This one cracks me up every time I’m in a bitcoin debate. The person who states this either didn’t do their research or just didn’t understand what they were reading.

Bitcoin is not just anotherGIF, JPEG, Tweet or simple file that can be altered at will. No one creates a bitcoin out of thin air by going to some website.

Simply put, Bitcoin is a public ledger of transactions authenticated and secured using…
