Simple API Overview with Bruno and cURL Guides
Categories: Change Log, Simple API, Tools
The 2025-04-13 update added a Simple API overview video, a Bruno page, and a cURL page.
This update was about lowering the barrier to API testing practice. A learner should be able to see an API, send a request, inspect the response, and repeat the same idea in more than one tool. Simple API, Bruno, and cURL work well together because they teach the same HTTP ideas through different interfaces.
Why Simple API Helps Beginners
Simple API is designed for safe CRUD practice. It does not require authentication, and it avoids free text fields that might encourage people to enter personal or inappropriate data.
That makes it a useful step after learning basic HTTP concepts. You can practise GET, POST, PUT, and DELETE without first setting up accounts, tokens, or sessions.
The API is also small enough that learners can understand the whole model. Items have predictable fields, requests can be repeated, and state changes can be checked directly. That is ideal for learning because the tester can focus on cause and effect: what did I send, what changed, and how did the server report it?
What the Simple API Video Adds
The video gives learners a guided overview before they start experimenting. That matters because beginner API testers can easily get lost in tooling before they understand the API itself.
The useful learning pattern is:
- Watch the overview to understand the API purpose.
- Send a simple
GETrequest. - Create data with
POST. - Read the created item back.
- Change it with
PUTorPATCH. - Delete it and confirm the final state.
This gives learners a complete CRUD loop. Once they can do that manually, they are much better placed to understand API test automation.
Why Include Bruno and cURL?
Bruno gives learners a graphical REST client for building requests and inspecting responses. cURL gives learners a command line view of the same HTTP ideas.
Using both is useful. A GUI client can make exploration faster, while cURL makes the request more explicit and easier to share in bug reports, documentation, and automation notes.
Bruno is helpful when a learner wants to save a small collection and repeat requests. cURL is helpful when the learner wants to see the request as a command that can be copied into documentation or used as the starting point for automation.
The combination also teaches an important testing skill: do not confuse the tool with the protocol. If a request works in Bruno and cURL, the learner can compare the headers, body, and response to understand what actually matters.
What This Update Adds for API Testing Practice
After watching the overview, try creating and retrieving an item in Simple API. Then repeat the same request in both Bruno and cURL so you can compare how each tool presents the request and response.
That comparison is valuable. Some clients add default headers. Some hide redirects or cookies. Some format response bodies automatically. Running the same request in two tools helps learners spot those differences and become more careful observers.
