Tutorials, tips, and news on Craft CMS.
In a recent lesson, I walked through how to use the Element API Plugin from Pixel & Tonic to create a JSON API that shares your website's data (only that data which you choose, of course) for consumption by another website or service.
The free lesson is a fundamental approach to building a read-only API using the default ElementTypes (entry, category, asset, etc) in Craft. As long as you follow my steps, you can get an API up and running quickly.
Toward the end of the lesson, we also learn how to expose your Craft Commerce order data via an API so you can have an outside tool (like a Goole Spreadsheet or reporting tool) ingest it and use it create some sort of report.
