What API2Cart Is Evaluating for Wave Accounting Integration
Candidate data flow
Sales and customer activity for simple bookkeeping and invoicing flows. The final entity and method list will be based on verified vendor API capabilities rather than assumptions.
Operational outcome
The intended workflow is to reduce manual entry when online orders become accounting transactions. Record ownership and idempotency would be defined before write operations are enabled.
Accounting safeguards
The connector would need to preserve fees, discounts, refunds, and payment-status changes. Orders, invoices, payments, refunds, settlements, and journal entries would not be treated as interchangeable records.

What We Know About Wave Accounting So Far
Based on Wave Accounting’s own documentation and API2Cart’s discovery process — not a promise of a release date.
API & Integration. Wave exposes a single GraphQL endpoint (gql.waveapps.com/graphql/public) rather than a REST API, authenticated via OAuth 2.0 authorization code flow for any third-party or published integration; a full-access personal token exists but is explicitly restricted to development/personal use, not production integrations. Access tokens expire after roughly two hours and require a refresh-token exchange for continued access, and the API supports webhooks for event notifications. As of May 2025, third-party app connections require the connected Wave business to hold an active Wave Pro subscription, which can gate integration availability for some prospective customers.
Is this integration live yet? No. Wave Accounting integration is not live yet. Authentication, entities, fields, write operations, webhooks, limits, regional availability, and release timing remain subject to technical discovery and customer demand.
What’s the integration challenge? Engineering discovery must validate API availability, business permissions, and supported transaction depth. Unsupported objects or operations would remain outside the published scope.
How is a release decided? Roadmap evaluation includes API maturity, sandbox access, accounting correctness, customer demand, maintenance cost, data residency, rate limits, and overlap with existing connectors. The page records an integration candidate; it does not promise a release date.
Technical validation. Engineering discovery must validate API availability, business permissions, and supported transaction depth. Unsupported objects or operations would remain outside the published scope.
