Expense Attachments — Proposed Guide

Overview

Attachments associate supporting files with an expense without embedding file bytes in the ordinary expense representation. Metadata and authorized file access are separate concerns.

Key concepts

Track file type, size and purpose. An attachment can be supporting evidence without being a receipt.

Implementation considerations

Future access links must have explicit authorization and expiry semantics. This documentation provides no real upload or download service.

Proposed API behavior

GET /v1/expenses/{expense_id}/attachments 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/attachments' \
  -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.

Illustrative error case

Review this failure case in context: Future access links must have explicit authorization and expiry semantics. This documentation provides no real upload or download service.

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 expense attachments 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.
attachment_id	string	Stable fictional attachment reference; not a secret and not evidence that a resource exists.
content_type	string	Illustrative media type that would need validation before any future file transfer.
size_bytes	integer	Illustrative file size in bytes; no upload limit is committed.
