In addition to these, I think that Google's API Design Guide (https://cloud.google.com/apis/design) and their AIPs (https://aip.dev) are good references for learning about how their style of APIs, called resource-oriented APIs, can be designed. There is a linter that can check whether an API follows the AIPs (I know, these acronyms are easy to mix up), available at https://linter.aip.dev. I am building a side project following the AIPs and have found them to be very helpful.

Thanks. Do you have some resources how Google Artman fits into this? It looks like mix/match of Protobuf with Yaml to define a Rest Api. But I don’t see it promoted very much except with the cloud endpoint
