Setting up Wave Accounting
From the connector definition itself: where to find the credentials, what they need to be allowed to do, and which API this adapter talks to.
This connector wraps the Wave GraphQL API (gql.waveapps.com/graphql/public).
Setup:
- Sign in to https://my.waveapps.com → bottom-left avatar → Manage Applications → Create Application.
- Use the OAuth flow to obtain an access token, OR (faster) generate a Full Access Token from the application settings (single-tenant).
- Business ID: Wave is multi-business — call
wave_get_businessesand take theidof the business to work in. - Set
WAVE_ACCESS_TOKENandWAVE_BUSINESS_ID.
Authentication: Authorization: Bearer ${WAVE_ACCESS_TOKEN}.
Every business-level tool takes business_id (customers, products, invoices, accounts, and reading one invoice): Wave reaches all of them through business(id: …). Pass the ID from wave_get_businesses on each call.
GraphQL-only: Wave has no REST. The auto-injected GraphQL builtins (wave_accounting_graphql_query, wave_accounting_graphql_mutation, wave_accounting_graphql_schema) are available for arbitrary queries. The typed wrappers below cover the most common cases.
Pagination is by page, not cursor: list tools take page (1-based) and page_size (Wave's default is 45), and answer with pageInfo { currentPage totalPages totalCount }. Ask for the next page while currentPage < totalPages.
Money is a { value, currency } object: value is a decimal string in major units ("12.50"), minorUnitValue the same amount in cents.
Mutations answer with didSucceed and inputErrors { path message } rather than an HTTP error: didSucceed: false means Wave refused the change — read inputErrors.
Rate limits: 60 req/min per token + complexity budget. 429 with Retry-After.
Out of scope here: payroll, payment-processing setup, bank-feed reconciliation UI.
