Talk preparation:

1. Decide my "call to action"

• make an outline
• Include a summary slide of main points (take-aways)

2. Create a story
3. Test the talk for effectiveness

• have the audience do stuff

4. Create the slides, make intro slide last.

• add my contact information to every slide
• create a link to Resources like the talk. Github is my preferred location.

5. Practice the talk multiple times until I know how long it takes.

Bonus: Don’t Overthink

Call to action

Getting started with Postman. Introduction talk meant to be less than 10 minutes.

Talk Summary

Short introduction on what Postman is and how to GET data with their no-code application.

• What is HTTP status Code
• What is API
• How does Postman help?
• How to Make a Get request.

What is HTTP status Code

Resource for front end questions https://developer.mozilla.org/en-US/

HTTP Status codes https://developer.mozilla.org/en-US/docs/Web/HTTP/Status

• HTTP status codes are returned by the server to tell the browser how the "HTTP Request" was handled.
• Front end is happy with success (200). Any other response can be problematic.
• Postman is an API testing platform. Postman shows the http status codes for a request and much more.

What is API

List of Public APIs https://github.com/public-apis/public-apis

• Application Programming Interface (API) allows two programs to communicate with each other.
• HTTP is a collection of rules for transmission of data on the world wide web.
• APIs primarly use 4 Request Methods.
  • GET retrieves data from an API.
  • POST sends new data to an API.
  • PUT update existing data.
  • DELETE removes existing data.
• Web APIs are browser URLs (https://postman-echo.com/get)
  1. API URL connects to External system
  2. External system reads parameters send with URL
  3. External system resolves request
  4. External system returns a response with HTTP status code

How does Postman help?

Postman documentation & tutorials https://learning.postman.com/docs/getting-started/introduction/

Navigating Postman https://learning.postman.com/docs/getting-started/navigating-postman/

• Postman simplifies APIs so developers can test APIs without writing any code.
• Since we use Postman instead of doing the coding ourselves we must learn the application interface and other things that are only specific to Postman and not all API designs.

How to Make a Get request.

Send first request with Postman https://learning.postman.com/docs/getting-started/sending-the-first-request/

Workflow to know

1. Click New [button]
2. Select "HTTP Request"
3. Paste in API URL
4. Click Send [button]
5. Read "Body" that comes back with the server response

Add credentials to API
