QuickBooks Online integrationBuild cloud accounting flows
that stay in sync.
Zaptiva connects QuickBooks Online to commerce, CRM, operations, payroll-adjacent workflows, reporting, and approvals through Intuit's REST platform.
Cloud APIs still need state, identity, and reconciliation.
QuickBooks Online integrations use OAuth 2.0 and operate within an authorized company realm. REST resources, references, query behavior, webhook notifications, change-data capture, minor versions, and rate limits must be handled deliberately.
What QuickBooks Online
is built to manage.
QuickBooks Online is cloud accounting software for invoicing, expenses, banking, payments, purchasing, reporting, projects, and—in applicable plans—inventory, classes, locations, custom fields, and workflow automation. Capability and user limits vary by subscription and country edition.
Its REST Accounting API uses OAuth 2.0 and a company realm identifier. Zaptiva designs around supported entities, sparse updates, reference fields, change data, webhooks, and the fact that accounting records often depend on customers, items, accounts, tax settings, and other records already existing in the company.
Cloud accounting
Coordinate customers, vendors, invoices, bills, payments, purchases, bank activity, accounts, and financial reporting.
Projects + dimensions
Depending on plan, track project profitability, classes, locations, custom fields, budgets, and role-based workflows.
REST API ecosystem
OAuth-authorized applications can query and update supported accounting entities for a connected company.
Event-driven synchronization
Webhooks and change-data queries can reduce polling while reconciliation catches missed, reordered, or failed events.
OAuth 2.0 + realm-scoped REST
Zaptiva maintains encrypted tokens, scopes every request to the correct realm, consumes change notifications, and reconciles source and QuickBooks identifiers.
Accounting REST API
JSON resources support supported customers, vendors, items, transactions, accounts, and queries in an authorized realm.
Webhooks
Signed notifications indicate changed entities; the integration then retrieves current state rather than treating the notification as the full record.
Change Data Capture
CDC queries help recover changes after downtime and complement webhooks in a resilient synchronization design.
Every movement has a source, a rule, and a result.
The workflow is designed for auditability and recovery—not just a successful demo.
Authorize
An administrator grants the Intuit app access and Zaptiva stores renewable tokens securely.
Normalize
External records are mapped to QuickBooks references, tax, currency, item, and account rules.
Exchange
REST requests use the target realm and supported API/minor version.
Reconcile
Webhooks, CDC, IDs, sync tokens, and source totals keep both sides aligned.
The records teams
actually work with.
Scope is confirmed against the installed edition, modules, permissions, and current vendor interface before build.
Built to survive real operations.
Technical decisions stay visible to finance, operations, and IT.
Token lifecycle
Refresh, revocation, disconnect, and least-privilege handling are part of the operating design.
Reference integrity
Transactions are not submitted until required accounts, items, customers, and tax references resolve.
Webhook recovery
Notifications are verified, deduplicated, and backed by scheduled reconciliation or CDC.
Put the connection
to useful work.
Choose a focused operating problem, prove the flow, and build from a reusable foundation.
What teams ask
before the build.
Practical answers for architecture, compatibility, deployment, and ownership.
Do webhooks contain the complete changed transaction?＋
They are best treated as change notifications. The integration retrieves the current entity and applies idempotent synchronization logic.
Can one connection access multiple companies?＋
Authorization and requests are realm-specific. Multi-company designs maintain distinct connection and reconciliation state for each authorized company.
Grounded in current product documentation.
Capabilities vary by edition, version, modules, licensing, and configuration. Zaptiva verifies the target environment during discovery.
