Initialize OAuth
POST/api/qbo/integrations/initialize
Generates a QBO OAuth authorization URL. Works for both initial setup and reconnection.
This endpoint currently requires session authentication; Personal Access Token scope support is in progress.
Optional environment (sandbox | production) selects which QuickBooks environment to connect to. It is honoured only on non-production servers (production always connects to production) and defaults to sandbox when omitted. For a reconnect the existing connection's environment is reused. The environment is fixed once connected - to switch, disconnect and reconnect.

Response Headers
Unauthenticated — the bearer token is missing, revoked, expired, or malformed. Never retry automatically; fix the credential. See the Errors guide.
Forbidden — the token lacks a required scope, the endpoint is not available to API tokens, or the user behind the token lacks the permission. A human must adjust the token scopes or user permissions; do not retry.
Validation failed — the body is a field → messages map (Laravel shape) or the platform envelope with a stable machine-readable code. Fix the payload and resubmit.
Rate limited — platform limit is 1,000 requests/min; individual tokens may carry lower limits. Honor the Retry-After header before retrying. See the Rate Limits guide.
