Overview

REST-style resources expose representations through consistent HTTP methods. This user retrieval example illustrates a read that should not create an invitation, alter a profile or initiate a financial workflow.

Key concepts

GET reads a representation; POST usually requests creation or a named action; PATCH proposes partial changes. A resource identifier belongs in the path, while filters belong in the query.

Implementation considerations

Do not infer idempotency from a method name alone. Future specifications must define retries, permissions and business side effects for each operation.

Proposed API behavior

GET /v1/users/usr_example_123 is an illustrative design for this topic. Path and field names may change before implementation. Access would require an authorized organization context and operation-specific permission; no public API or authorization grant is available here.

Static example requests

# Proposed request text only; this reserved host is not a live API.
curl -X GET 'https://api.remizen.example/v1/users/usr_example_123?user_id=usr_example_123' \
  -H 'Authorization: Bearer YOUR_API_KEY'

Fictional response example

{
  "data": [
    {
      "organization_id": "org_example_123",
      "id": "usr_example_123",
      "display_name": "Taylor Example",
      "email": "taylor@example.com",
      "status": "active"
    }
  ],
  "pagination": {
    "has_more": false,
    "next_cursor": null
  },
  "meta": {
    "request_id": "req_example_123",
    "reference_only": true
  }
}

Illustrative error case

Review this failure case in context: Do not infer idempotency from a method name alone. Future specifications must define retries, permissions and business side effects for each operation.

{
  "error": {
    "code": "validation_error",
    "message": "The proposed understanding rest apis operation requires review of its input or authorization.",
    "request_id": "req_example_123"
  }
}
