Bits & Pieces
Note to self: looked at: Adidas, Maturity, Atlassian, Whitehouse, Google, Microsoft, Heroku

Typical Structure & Aspects


 * Documentation
 * discoverable specs and schemas
 * HTTP binding
 * use of verbs, HATEOAS, idempotence (put vs post vs patch)
 * see https://cloud.google.com/apis/design/standard_methods?hl=en
 * see google's idea for custom verbs
 * changing collections https://github.com/microsoft/api-guidelines/blob/vNext/Guidelines.md#95-changing-collections
 * use of error codes, body of error responses
 * content types & negotiation
 * caching
 * conditionals
 * redirects (normalization, deprecation, and other)
 * other headers
 * guidance on urls vs header vs query param
 * resources vs entities
 * etags, see https://cloud.google.com/apis/design/design_patterns?hl=en#etags
 * payload data
 * serialization (JSON)
 * shared data model
 * standard data types (date format, language codes, etc)
 * standard field names (rel, ref, etc) - compare https://cloud.google.com/apis/design/standard_fields?hl=en
 * schemas
 * pagination, ordering, filtering
 * https://github.com/microsoft/api-guidelines/blob/vNext/Guidelines.md#98-pagination
 * response for long running operations?
 * standard query params: localization, variants, flavor, embedding/expansion
 * batch operations and collections (put vs post)
 * foreign key relation (entitiy URLs)
 * domains and bounded contexts, separation of concerns
 * no data in keys (really? maps are neat...)
 * errors, compare https://cloud.google.com/apis/design/errors?hl=en
 * Evolution
 * Versioning
 * URL vs headers, etc
 * content negotiation
 * deprecation
 * headers? https://datatracker.ietf.org/doc/html/draft-dalal-deprecation-header-02
 * compatibility, see https://cloud.google.com/apis/design/compatibility?hl=en
 * URL structure
 * characters & encoding (slashes, colons, hashes, utf8, query params, etc)
 * resources & collections (sub-collections, formats, nested resources, etc)
 * nesting vs referense -> composition vs aggregation
 * use American English nouns (singlular or plural?) (kebab-case or CamelCase?)
 * searching vs. listing
 * formats / file extension suffix
 * Compliance
 * testing (pact)
 * SLA, rate limits
 * https://github.com/microsoft/api-guidelines/blob/vNext/Guidelines.md#143-retry-after-and-ratelimit-headers
 * Security
 * Authentication
 * CORS/CSP
 * CSRF
 * Design process (see also https://cloud.google.com/apis/design/resources?hl=en)
 * Model entities (resources, nouns) and their relationships
 * Design a URL scheme for addressing the resources and collections
 * Define schemas for representing the entities.
 * Determine the behavior of standard verbs for each resource (and collection)
