Overview

Retrieving an expense would return its authorized representation and references to supporting records. It should not expose unrelated cardholder or employee information.

Key concepts

Interpret amounts with currency and explicit minor-unit semantics. References to receipts and reports may need separate reads.

Implementation considerations

A retrieved status is a snapshot. Recheck version and business state before a future mutation rather than relying on a cached review screen.

Proposed API behavior

GET /v1/expenses/{expense_id} 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.

Proposed path parameters
Name	Type	Description
expense_idrequired	string	Stable fictional expense reference; not a secret and not evidence that a resource exists.

No additional request fields are illustrated; this is not a finalized contract.

Static example requests

Proposed, non-executing request examples

# Proposed request text only; this reserved host is not a live API.
curl -X GET 'https://api.remizen.example/v1/expenses/exp_example_123' \
  -H 'Authorization: Bearer YOUR_API_KEY'

Fictional response example

200 (proposed example)Static response fixture

Fictional documentation data only. No request was sent, record created, review performed, payment initiated or provider connection activated.

JSON

  "data": {
    "expense_id": "exp_example_123",
    "organization_id": "org_example_123",
    "version": 1,

Illustrative error case

Review this failure case in context: A retrieved status is a snapshot. Recheck version and business state before a future mutation rather than relying on a cached review screen.

422 (illustrative; final error contracts are undecided)Proposed error fixture

Synthetic diagnostic example. Human-readable messages must not be used as stable programmatic contracts.

JSON

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

Proposed data types

Illustrative field dictionary
Name	Type	Description
expense_id	string	Stable fictional expense reference; not a secret and not evidence that a resource exists.
organization_id	string	Stable fictional organization reference; not a secret and not evidence that a resource exists.
version	integer	Illustrative resource revision for detecting stale updates; no live concurrency contract is published.
