Setup:

  2. Use the OAuth flow to obtain an access token, OR (faster) generate a Full Access Token from the application settings (single-tenant).
  3. Business ID: Wave is multi-business — find your business ID via the wave_get_businesses query or in the URL of any Wave page.
  4. Set WAVE_ACCESS_TOKEN and WAVE_BUSINESS_ID.

Authentication: Authorization: Bearer ${WAVE_ACCESS_TOKEN}.
