What its author says it does

Copied from the file, not written here

Kashflow integration via Apideck's Accounting unified API — same methods work across every connector in Accounting, switch by changing `serviceId`. Use when the user wants to read, write, or reconcile invoices, bills, payments, ledger accounts, and journal entries in Kashflow. Routes through Apideck with serviceId "kashflow".

Kashflow (via Apideck)

Access Kashflow through Apideck's Accounting unified API — one of 34 Accounting connectors that share the same method surface. Code you write here ports to Access Financials, Acumatica, banqUP and 30 other Accounting connectors by changing a single serviceId string. Apideck handles auth, pagination, rate limiting, and retries so you don't write per-tenant Kashflow plumbing.

Beta connector. Kashflow is currently in beta on Apideck. Expect partial resource coverage and occasional mapping gaps. Always verify coverage (see below) and fall back to the Proxy API for unsupported operations.

When to use this skill

Activate this skill when the user explicitly wants to work with Kashflow — for example, "create an invoice in Kashflow" or "reconcile payments in Kashflow". This skill teaches the agent:

Which Apideck unified API covers Kashflow (Accounting)
The correct serviceId to pass on every call (kashflow)
Kashflow-specific auth and coverage caveats

For the full method surface (parameters, pagination, filtering), use your language SDK skill:

apideck-node, apideck-python, apideck-dotnet, apideck-java, apideck-go, apideck-php, or apideck-rest

For the raw OpenAPI spec:

Accounting: https://specs.apideck.com/accounting.yml · API Explorer

Minimal example (TypeScript)

import { Apideck } from "@apideck/unify";

const apideck = new Apideck({
  apiKey: process.env.APIDECK_API_KEY,
  appId: process.env.APIDECK_APP_ID,
  consumerId: "your-consumer-id",
});

// List invoices in Kashflow
const { data } = await apideck.accounting.invoices.list({
  serviceId: "kashflow",
});

Portable across 34 Accounting connectors

The Apideck Accounting unified API exposes the same methods for every connector in its catalog. Switching from Kashflow to another Accounting connector is a one-string change — no rewrite, no new SDK.

// Today — Kashflow
await apideck.accounting.invoices.list({ serviceId: "kashflow" });

// Tomorrow — same code, different connector
await apideck.accounting.invoices.list({ serviceId: "access-financials" });
await apideck.accounting.invoices.list({ serviceId: "acumatica" });

This is the compounding advantage of using Apideck over integrating Kashflow directly: code against the unified Accounting API once, gain access to every connector in it. New connectors Apideck adds become available to your app without code changes.

Kashflow via Apideck Accounting

Kashflow is a UK-focused cloud accounting platform for SMB, owned by IRIS Software Group. Straightforward coverage of the standard UK accounting entity set.

Entity mapping

Kashflow entity	Apideck Accounting resource
Invoice	`invoices`
Bill / Purchase Invoice	`bills` (partial)
Credit Note	`credit-notes`
Customer	`customers`
Supplier	`suppliers`
Item	`invoice-items`
Nominal Code	`ledger-accounts`
Journal	`journal-entries`
VAT	`tax-rates`
Payment	`payments`
Company Info	`company-info`

Coverage highlights

✅ Full CRUD on invoices, customers, suppliers
✅ Credit notes
✅ Journal entries
✅ Tax rates (UK VAT)
✅ Payments
⚠️ Payroll integration (Kashflow Payroll) — separate product surface; use Proxy
❌ Bank feeds — limited; use Proxy
❌ MTD-specific VAT return submissions — use Proxy

Auth notes

Type: Basic auth (API username + password), managed by Apideck Vault
Company binding: one Kashflow company per connection.
Legacy flavor: Kashflow's API is SOAP-based under the hood; Apideck abstracts this. Proxy calls still use SOAP envelopes.

Example: list recent invoices

const { data } = await apideck.accounting.invoices.list({
  serviceId: "kashflow",
  filter: { updated_since: "2026-04-01T00:00:00Z" },
});

Escape hatch: Proxy API

When an endpoint isn't covered by the Accounting unified API, use Apideck's Proxy to call Kashflow directly — Apideck injects auth headers and handles token refresh. Set x-apideck-downstream-url to the target endpoint on Kashflow's own API:

curl 'https://unify.apideck.com/proxy' \
  -H "Authorization: Bearer ${APIDECK_API_KEY}" \
  -H "x-apideck-app-id: ${APIDECK_APP_ID}" \
  -H "x-apideck-consumer-id: ${CONSUMER_ID}" \
  -H "x-apideck-service-id: kashflow" \
  -H "x-apideck-downstream-url: <target endpoint on Kashflow>" \
  -H "x-apideck-downstream-method: GET"

See Kashflow's API docs for available endpoints.
