REST API Cheatsheet

Source: https://www.youtube.com/watch?v=5WXYw4J4QOU

• POST, GET, PUT, DELETE != CRUD
• no verbs -> just nouns for Resources: /applications or /applications/123
• Possible Responses: Collection of Resources (e.g. with Links) or One instance of a Resource
• Keep your API course grained to be scaleble to future requirements
• For Resources: Be as specific as possible: /customers vs. /newsletter-customers and /registered-customers
• PUT for Create: Can be used when the Client has the ability to create an identifier for the Resource himself. But it has to contain a full replacement of the dataset: PUT /applications/123
