Wave

At a Glance

Difficulty

⚡MODERATESelf-Service OAuth App + Wave Approval Required to Distribute

Authentication

OAuth 2.0OAuth 2.0 authorization code flow. Wave's API is GraphQL-only, and each connection also needs the consumer's Wave Business ID.

Webhooks

No webhooks — none surfaced by this connector, so poll for changes.

Partnership Required

No

Apideck Credentials

Not available(Not available — register your own Wave application and add its Client ID and Secret to Apideck.)

Costs

Wave charges no API access fees and commits to advance notice before introducing any. The subscription requirement sits on the connecting business, not you.

Sandbox Availability

Not available(No sandbox environment. A free Starter account is a sufficient test environment and exposes the same API surface as Pro.)

Account Type Required

A Wave business in the US or Canada with an active Pro or Advisors subscription. Testing your own app against your own account needs neither.

Consumer Access Level

Any user with access to the business can authorise the connection; Wave publishes no role requirement.

Rate Limits

Wave publishes no rate limits; its documented error codes include no throttling or rate-limit code.

Responsibility matrix

Environments

Single environment

Testing and production share one Wave host and one credential shape, because Wave runs no sandbox. To test: create a free Wave account and add as many test Businesses as you need — a Starter account exposes the same API surface as Pro — or request Apideck temporary shared test credentials at https://help.apideck.com/en/articles/7774658.

Signing up from outside North America

Set a VPN to the US or Canada and use an email address you have not tried before, then create the business as US-based with USD as its currency. Getting this wrong on the first attempt tags the address permanently, and no later attempt from that address succeeds. If you are already blocked, Wave can unblock addresses manually on request.

Caution

A test Business sits in the same Wave account as any real books you keep there, and the Business ID is the only thing separating them at connection time. Check which one you have connected before writing.
