accounted-api

Consume the Accounted REST API (Swedish double-entry bookkeeping SaaS, https://app.gnubok.se/api/v1). Use when building an integration, app, backend job, or agent tool layer against Accounted: invoices, customers, suppliers, supplier invoices, journal entries (bokföring), bank transactions and reconciliation, payroll (lön), VAT/moms and financial reports, SIE import/export, documents, webhooks. Covers auth with gnubok_sk_ API keys, conventions (dry-run, idempotency, cursor pagination, scopes), and all 145 endpoints.

Accounted API integration

Accounted is Swedish double-entry bookkeeping (bokföring) as a service: BAS chart of accounts, verifikationer with legally immutable audit trails, VAT (moms), payroll (lön), invoicing, bank reconciliation, and statutory reports, exposed as a REST API designed for agents and integrations first.

This skill is for building software against the REST API (an app, a backend job, an agent tool layer). If the goal is to operate a ledger conversationally (book receipts, run month close), use the Accounted MCP connector and its workflow skills instead: install the accounted plugin or see https://app.gnubok.se/docs/api/connect-claude.

If you have used Stripe's API the shape will feel familiar: bearer keys, dated versions, idempotency keys, webhook signatures, cursor pagination. The domain rules are Swedish accounting law; the Gotchas section below stops the classic violations before you ship them.

Auth and base URL

Every request sends a bearer key:

curl https://app.gnubok.se/api/v1/companies \
  -H "Authorization: Bearer gnubok_sk_live_..."

• Base URL: https://app.gnubok.se/api/v1 (legacy machine host, permanent). https://app.accounted.se/api/v1 serves the identical API.
• Keys are created in the Accounted dashboard under Settings -> API (/settings/api). Two prefixes:
  • gnubok_sk_live_* commits real writes.
  • gnubok_sk_test_* reads real company data but forces every write into dry-run (responses carry X-Gnubok-Mode: test). Develop and run evals with a test key; switch to live last.
• Each key carries scopes (invoices:read, invoices:write, payroll:write, webhooks:manage, ...). Every endpoint in the index below is annotated with its required scope; a missing scope returns 403.
• Rate limit: 100 requests/minute per key. On 429, honor Retry-After.
• URLs carry the company id explicitly (/api/v1/companies/{companyId}/invoices). A key can act on any company its user is a member of; start every session with GET /api/v1/companies to discover ids. There is no implicit "current company".

First calls, in order: GET /api/v1/health (no auth, connectivity), then GET /api/v1/companies (auth works, discover companyId).

Conventions

These rules hold across the whole surface; endpoint entries below do not repeat them.

Response envelope. Success: { "data": ..., "meta": { "request_id", "api_version", "next_cursor"?, "audit"?, "partial_expansions"? } }. Errors replace data with error (no meta; request_id moves inside error).

Errors. Stable machine codes with agent-oriented remediation:

{ "error": { "code": "PERIOD_LOCKED", "message": "Svenska", "message_en": "English",
  "details": {}, "recovery_hint": "next step", "docs_url": "...",
  "valid_alternatives": {}, "request_id": "req_..." } }

React to code, read message_en and recovery_hint, follow valid_alternatives when present (e.g. next_open_period). Standard codes on every endpoint: 400 validation, 401 bad key, 403 missing scope, 404, 429 rate limited (honor Retry-After), 500. Full catalogue: https://app.gnubok.se/docs/api/errors. Only endpoint-specific codes are mentioned per endpoint below.

Cursor pagination. List endpoints take ?cursor= and return meta.next_cursor; loop until it is absent/null. A stale or tampered cursor is NOT an error: the first page is returned again, so terminate on next_cursor, never on "page looks familiar".

Dry-run on every write that supports it (dry-run badge in the index). Send ?dry_run=true (or X-Dry-Run: true): the response is always 200 with data.dry_run: true plus a preview (would-be record, journal lines, voucher number) and the X-Dry-Run: true response header; nothing is committed. Commit by re-issuing without the flag and with the SAME Idempotency-Key (the dry run is not cached against the key). Preview first on any financial write; it is free.

Idempotency-Key. Send a fresh UUID header on every POST/PATCH/DELETE; several endpoints reject writes without one (400). Replaying the same key+body returns the original response with the Idempotent-Replayed: true header; the same key with a different body returns 409 IDEMPOTENCY_KEY_REUSE (24h window). Safe retry loop: keep the key, keep the body.

Test keys are simulation-only. With a gnubok_sk_test_* key, reads return real company data (responses carry X-Gnubok-Mode: test) and every write is forced into dry-run; writes that cannot be simulated return 403 TEST_KEY_WRITE_BLOCKED. Nothing a test key does ever persists: it is ?dry_run=true baked into the credential. Full end-to-end write tests therefore need a live key against a company you own.

Atomic writes. A mutation either commits fully or errors with no side effects. There is no partial state to clean up after an error response (bulk-create endpoints that do partial success say so explicitly).

Audit inline. Successful financial writes include meta.audit (voucher number, audit-trail URL, immutability timestamp). No follow-up read needed to confirm what was booked.

Expansion. Some list/detail endpoints take ?expand=a,b (documented per endpoint). If an expansion fails the response still succeeds and names the failed parts in meta.partial_expansions; check it before trusting expanded fields.

Async operations. Long-running actions (fiscal-period lock/close/year-end, imports) return 202 with an operation id; poll GET /api/v1/operations/{id} until status is succeeded/failed. The response shape is identical whether the work ran inline or queued.

Versioning. Dated versions (current: see meta.api_version). Responses carry the Gnubok-Version header; request pinning via a Gnubok-Version request header is reserved for a future breaking change and is not read today. Additive changes ship without a version bump; see https://app.gnubok.se/docs/api/versioning.

Index badges. Every operation line below carries machine-readable annotations from the spec: scope: (required key scope), risk: (low/medium/ high; confirm with a human before unprompted high-risk calls), idempotent (safe to retry), dry-run (previewable), reversible (a single follow-up call can undo it, e.g. invoice credit).

Gotchas (Swedish accounting domain)

Rules a generic REST integration will violate unless told:

• Account numbers are strings, not numbers. BAS accounts ("1930", "3001") are identifiers; send them as JSON strings. Arithmetic on them, zero-stripping, or number coercion corrupts postings.
• Posted journal entries are immutable by law (Bokföringslagen). There is no PATCH or DELETE on a committed entry, ever. Undo with POST .../journal-entries/{id}/reverse (storno), fix with POST .../journal-entries/{id}/correct. Design flows around reverse-and-repost, not edit-in-place.
• Voucher numbers are gapless and server-assigned. Never assume or pre-allocate one; read it from meta.audit.voucher_number after commit. A legally required gap explanation goes through POST .../voucher-gap-explanations.
• Every entry balances. sum(debit) === sum(credit) to the öre, amounts are decimal SEK numbers (max 2 decimals). Do rounding with round-half-away-from-zero on öre; never float-accumulate line totals client-side and "fix" the difference on a random line.
• Period locks are a feature, not an error to retry. Writes into a locked/closed period return PERIOD_LOCKED (with valid_alternatives pointing at open periods). Retrying the same request cannot succeed; either target an open period or surface the lock to the user.
• Drafts vs posted. Invoices are created as drafts with invoice_number: null; the F-series number is assigned atomically on send. Journal entries follow draft -> commit. Nothing financial exists in the ledger until the commit/send action.
• Two invoice worlds. invoices = accounts receivable (you bill customers); supplier-invoices = accounts payable (you receive bills). They are different resources with different lifecycles.
• Swedish user-facing text. error.message is Swedish by design; show it to Swedish end users, and use message_en for your own logs/logic. Domain terms in responses (moms, verifikat, kostnadsställe) are not translatable labels but legal concepts.
• Compliance pre-flight. Before building your own validation for Swedish rules, call GET .../compliance/check: it runs the server's own rule set (VAT plausibility, sequence integrity, period status) and returns findings.

Verification

This skill is generated (npm run apiskill:generate in the Accounted repo) from the same endpoint registry that serves the live API, its OpenAPI spec (https://app.gnubok.se/api/v1/openapi.json), and its runtime request validators, so schema drift between this text and the server cannot occur for a matching api_version. CI regenerates and diffs it on every change.

Before first use in a new environment, smoke-test:
