What its author says it does

Copied from the file, not written here

Wave 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 Wave. Routes through Apideck with serviceId "wave".

Wave (via Apideck)

Access Wave 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 Wave plumbing.

Beta connector. Wave 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 Wave — for example, "create an invoice in Wave" or "reconcile payments in Wave". This skill teaches the agent:

Which Apideck unified API covers Wave (Accounting)
The correct serviceId to pass on every call (wave)
Wave-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 Wave
const { data } = await apideck.accounting.invoices.list({
  serviceId: "wave",
});

Portable across 34 Accounting connectors

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

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

// 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 Wave 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.

Wave via Apideck Accounting

Wave is a free US/CA accounting platform popular with small businesses and freelancers. Coverage is read-oriented for reporting, and invoicing is the primary write path.

Entity mapping

Wave entity	Apideck Accounting resource
Invoice	`invoices`
Customer	`customers`
Vendor	`suppliers`
Account	`ledger-accounts`
Product	`invoice-items`
Sales Tax	`tax-rates`
Bank Account	`bank-accounts`
Business	`company-info`
P&L, Balance Sheet	`profit-and-loss`, `balance-sheet`
Bank Feed Statements	`bank-feed-statements`

Coverage highlights

✅ Invoices (CRUD)
✅ Customers, suppliers, products
✅ Tax rates and chart of accounts
✅ Financial reports (P&L, Balance Sheet)
✅ Bank feed statements
⚠️ Bill / expense management — limited; use Proxy for Wave's specific bill endpoints
❌ Payroll — Wave Payroll is a separate product surface
❌ Receipt scanning — Wave-specific feature

Auth notes

Type: OAuth 2.0, managed by Apideck Vault
Business binding: one Wave business per connection. Multi-business users need separate connections.
GraphQL upstream: Wave's API is GraphQL; Apideck translates unified REST calls into GraphQL queries. For complex reads, the Proxy API forwards raw GraphQL.

Example: list customers with contact details

const { data } = await apideck.accounting.customers.list({
  serviceId: "wave",
  fields: "id,display_name,email,phone,addresses",
});

Escape hatch: Proxy API

When an endpoint isn't covered by the Accounting unified API, use Apideck's Proxy to call Wave directly — Apideck injects auth headers and handles token refresh. Set x-apideck-downstream-url to the target endpoint on Wave'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: wave" \
  -H "x-apideck-downstream-url: <target endpoint on Wave>" \
  -H "x-apideck-downstream-method: GET"

See Wave's API docs for available endpoints.
