When I see “REST API” I can safely assume the following:

• The API returns JSON
• CRUD actions are mapped to POST/GET/PUT/DELETE
• The team constantly bikesheds over correct status codes and at least a few are used contrary to the HTTP spec
• There’s a decent chance listing endpoints were changed to POST to support complex filters

Like Agile, CI or DevOps you can insist on the original definition or submit to the semantic diffusion and use the terms as they are commonly understood. - Most RESTful APIs aren’t really RESTful / HN
