My Top 5 Apex APIs and Bonus

April 11, 2021 by Andrew Fawcett 1 Comment

As readers of this blog will already have determined, I love API’s! So when I was approached by the team at 100 Days of Trailhead to share my Top 5 “things” my mind fell to API’s. This is a short blog post because effectively the brief was a 10 minute video! Well ok I ran a bit over in the end so its actually 15 minutes.

In the video I cover 5 Apex API’s and a Bonus API at the end. Thank you for 100 Days of Trailhead for asking to contribute and please do check out all the other amazing content they have on their website! You can watch the video below (or link here) and find full source code in this GitHub repository.
