View OpenAPI Spec

Apideck Accounting is a unified API that maps a single schema for invoices, bills, payments, ledger accounts, customers, suppliers, and tax rates onto many downstream accounting platforms such as Xero, QuickBooks, Sage, NetSuite, and FreshBooks. The 95 operations cover the day-to-day finance objects most apps need plus reports like Balance Sheet, Profit and Loss, and Aged Debtors. Apideck routes each call through Apideck Vault, so customer credentials for the underlying platform stay in Apideck's vault instead of being passed in by the calling app.

Use Cases

Patterns agents use Accounting API API for, with concrete tasks.

★ SaaS Billing to Ledger Sync

Push invoices from a SaaS billing system into whichever accounting platform a customer uses (Xero, QuickBooks, Sage, NetSuite, FreshBooks) using a single integration. Apideck's /accounting/invoices endpoint accepts a normalised invoice payload, and the unified API translates it into the native object on the connected ledger. SaaS finance teams typically replace 5+ direct integrations with a single Apideck contract this way.

POST a new invoice to /accounting/invoices with line items totalling $499.00 and the customer reference, then verify the response shows the invoice was created on the connected ledger

Expense and Bill Capture

Forward supplier bills and expenses captured by an OCR or expense-management app into the customer's accounting platform of choice. Apideck's /accounting/bills, /accounting/expenses, and /accounting/bill-payments endpoints accept the unified payload and write to whichever ledger the customer uses. The integration is the same whether the customer runs Xero, QuickBooks, or Sage.

POST a bill to /accounting/bills with the supplier reference and line items, then POST a payment to /accounting/bill-payments to mark it as paid

Financial Reporting Aggregation

Pull Profit and Loss, Balance Sheet, Aged Debtors, and Aged Creditors reports from many customers' ledgers into a single dashboard. Apideck returns each report in a consistent schema so a reporting tool does not need to translate between Xero P&L and QuickBooks P&L manually. Useful for FP&A vendors and lenders who underwrite loans against ledger data.

GET /accounting/profit-and-loss with start_date and end_date for the last quarter and store the returned line items in a reporting database

AI Agent Bookkeeping Assistant

Give an AI agent a tool that can read invoices, create bills, and reconcile payments in whichever accounting platform a customer uses. Through Jentic, the agent searches for an intent like 'create invoice in customer accounting platform' and gets the matching Apideck operation with its input schema. The agent does not need separate integrations per platform.

Search Jentic for 'create accounting invoice', load the /accounting/invoices schema, and execute with the customer reference and line items returned by the upstream conversation

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

All three Apideck headers (Authorization bearer, x-apideck-app-id, x-apideck-consumer-id) are stored encrypted in the Jentic vault and injected at execution time. Per-customer Apideck Vault tokens never enter the agent's prompt or logs.

Intent-based discovery

Agents search by intent (for example 'create accounting invoice' or 'fetch profit and loss') and Jentic returns the matching Apideck operation with its input schema, so the agent does not have to walk the 95-operation reference.

Time to first call

Direct Apideck integration: 1-3 days to wire the three required headers, handle Apideck Vault consumer onboarding, and map errors. Through Jentic: under 1 hour - search, load schema, execute.

Related APIs

Alternatives and complements available in the Jentic catalogue.

Alternative

Xero Accounting API

Native Xero accounting API for ledgers running on Xero

Choose Xero directly when the agent only operates on Xero ledgers and needs Xero-specific features (Bank Rules, Manual Journals) the unified abstraction does not surface

Alternative

Sage API

Native Sage Business Cloud accounting API

Choose Sage directly when the agent only operates on Sage Business Cloud and needs Sage-native objects the unified API does not expose

Complementary

Apideck CRM API

Apideck CRM unified API to read customer and deal records that drive invoices

Pair with Apideck CRM when the workflow pulls a closed deal from a CRM and creates an invoice on the linked accounting platform without two separate integrations

FAQs

Specific to using Accounting API API through Jentic.

What authentication does the Apideck Accounting API use?

Apideck uses three required headers per call: Authorization with a bearer API key, x-apideck-app-id with your Unify application id, and x-apideck-consumer-id with the end-customer reference stored in Apideck Vault. Through Jentic all three values are stored encrypted in the vault and attached to the request at execution time.

Which accounting platforms does the Apideck Accounting API cover?

Apideck Unify routes the unified accounting calls to downstream connectors including Xero, QuickBooks Online, Sage Business Cloud, NetSuite, FreshBooks, MYOB, and Wave. Use the x-apideck-service-id header to pin the call to a specific connector when a consumer has more than one connected.

Can I create an invoice with the Apideck Accounting API?

Yes. POST to /accounting/invoices with a body that includes the customer_id, currency, due_date, and line_items. Apideck translates the unified payload into the native invoice on the connected platform and returns the created object with the platform's invoice id.

What are the rate limits for the Apideck Accounting API?

Apideck Unify enforces rate limits at both the Unify layer and the underlying connector. The connector-side limit dominates in practice, so a Xero call respects Xero's limits and a QuickBooks call respects QuickBooks' limits. The API returns ConnectorRateLimitError on connector throttling and HTTP 429 on Unify throttling - retry with backoff in both cases.

How do I fetch a Profit and Loss report through Jentic?

Search Jentic for 'get profit and loss report', load the /accounting/profit-and-loss schema, and execute with start_date and end_date. The response returns the report rows in Apideck's unified shape, regardless of whether the connector is Xero or QuickBooks.

Is the Apideck Accounting API free?

Apideck Unify offers a free tier with capped requests; production use is billed per consumer connection. See https://www.apideck.com/pricing for current tiers and contact sales@apideck.com for volume pricing.
