# Dualentry — Accounting API: overview > Canonical URL: https://developers.apideck.com/apis/accounting/dualentry/overview DualEntry is an AI-native ERP platform built from the ground up for finance teams scaling from mid-market to IPO. - Status: live - Authentication: apiKey - **account type required:** Any DualEntry plan. Multi-company tenants supported; scope to a Default Company or the whole tenant. - **apideck credentials available:** false - **apideck credentials note:** Each consumer supplies their own API key; there is no shared Apideck credential. - **authentication note:** Sent in the X-API-KEY header, not OAuth. The key is a long-lived organisation credential with no expiry. - **consumer access level:** Organisation administrator — only an admin can generate the API key, via Settings > Organization > Developer access. - **costs:** No separate API fee — bundled into the DualEntry subscription, which lists Open API as a plan feature. - **difficulty:** moderate - **difficulty reason:** API Key Authentication — Credential Generated by the Consumer's DualEntry Administrator - **environment notes:** - **description:** Development and testing against api-dev.dualentry.com. Credentials: a Development API key, generated by the consumer's DualEntry administrator and selected in Apideck by setting the connection's Environment to Development. There is no self-service sandbox signup — ask DualEntry for a development organisation. - **environment:** Sandbox - **description:** Live consumer data on api.dualentry.com. Credentials: a Production API key from the same administrator, with the connection's Environment left on Production. - **environment:** Production - **description:** Development credentials CANNOT be used with production accounts. The two environments hold separate organisations and separate keys, so swapping a key between them fails to authenticate rather than returning an error you can act on. - **environment:** Critical - **external guides:** - **source:** DualEntry - **title:** Rate Limiting - **url:** https://docs.dualentry.com/developers/guides/rate-limiting - **source:** DualEntry - **title:** How to Authenticate Your Requests - **url:** https://docs.dualentry.com/developers/guides/how-to-authenticate-your-requests - **important to know:** The API key is not self-service for you: the consumer's own DualEntry administrator must generate it, and DualEntry shows it only once at creation — if it is lost, a new key must be issued and the old one revoked. On a multi-company tenant, a read that does not name a company returns records from every company in the tenant. Set a Default Company on the connection, or send an x-apideck-company-id header per request. DualEntry offers no free trial. Every plan includes accountant-led implementation instead, so evaluating the platform means going through their onboarding rather than self-serving. - **partnership note:** Apideck holds an approved partnership with DualEntry, so no application or certification is required from you. - **partnership required:** false - **rate limits:** 300 requests/min per API key across all endpoints; 60 requests/min per endpoint; invoice create/update capped at 2/min. - **responsibility matrix:** - **area:** Generate the API key in DualEntry - **consumer:** ✓ (organisation administrator) - **apideck:** Docs provided - **area:** Configure the DualEntry connector - **customer:** ✓ - **apideck:** Securely stores credentials - **area:** Provide the API key - **consumer:** ✓ (via Vault) - **area:** Choose the environment and Default Company - **consumer:** ✓ (at connection time) - **apideck:** Maintains connector - **area:** Build via the Unified API - **customer:** ✓ - **apideck:** Updates the stored credential - **area:** Rotate the API key - **consumer:** ✓ (administrator) - **apideck:** Logs & alerts - **area:** Monitor connections - **consumer:** ✓ Can revoke anytime - **customer:** ✓ Via Dashboard - **sandbox available:** true - **sandbox note:** A separate Development environment at api-dev.dualentry.com with its own organisations and API keys; a production key will not authenticate there. - **sandbox url:** https://docs.dualentry.com/developers/guides/how-to-authenticate-your-requests - **supported resource categories:** - **name:** Sales & Receivables - **resources:** invoices invoice-items customers payments credit-notes - **name:** Purchases & Payables - **resources:** bills bill-credit-notes bill-payments suppliers purchase-orders expenses - **name:** Core Financial - **resources:** journal-entries ledger-accounts tax-rates - **name:** Organizational - **resources:** subsidiaries companies - **webhooks:** No webhooks — not supported by DualEntry's API. ## Supported resources [Accounting data model](/guides/accounting-data-model.md) - **custom field support:** false - **downstream id:** vendor-payments - **downstream name:** Vendor Payments - **id:** bill-payments - **name:** Bill Payments - **status:** live - **custom field support:** false - **downstream id:** bills - **downstream name:** Bills - **id:** bills - **name:** Bills - **status:** live - **custom field support:** true - **downstream id:** customer-credits - **downstream name:** Customer Credits - **id:** credit-notes - **name:** Credit Notes - **status:** live - **custom field support:** true - **downstream id:** vendor-credits - **downstream name:** Vendor Credits - **id:** bill-credit-notes - **name:** Bill Credit Notes - **status:** beta - **custom field support:** false - **downstream id:** customers - **downstream name:** Customers - **id:** customers - **name:** Customers - **status:** live - **custom field support:** false - **downstream id:** direct-expenses - **downstream name:** Direct Expenses - **id:** expenses - **name:** Expenses - **status:** live - **custom field support:** false - **downstream id:** items - **downstream name:** Items - **id:** invoice-items - **name:** Invoice Items - **status:** live - **custom field support:** false - **downstream id:** invoices - **downstream name:** Invoices - **id:** invoices - **name:** Invoices - **status:** live - **custom field support:** false - **downstream id:** journal-entries - **downstream name:** Journal Entries - **id:** journal-entries - **name:** Journal Entries - **status:** live - **custom field support:** false - **downstream id:** accounts - **downstream name:** Accounts - **id:** ledger-accounts - **name:** Ledger Accounts - **status:** live - **custom field support:** false - **downstream id:** customer-payments - **downstream name:** Customer Payments - **id:** payments - **name:** Payments - **status:** live - **custom field support:** false - **downstream id:** purchase-orders - **downstream name:** Purchase Orders - **id:** purchase-orders - **name:** Purchase Orders - **status:** live - **custom field support:** false - **downstream id:** subsidiaries - **downstream name:** Subsidiaries - **id:** subsidiaries - **name:** Subsidiaries - **status:** live - **custom field support:** false - **downstream id:** companies - **downstream name:** Companies - **id:** companies - **name:** Companies - **status:** beta - **custom field support:** false - **downstream id:** vendors - **downstream name:** Vendors - **id:** suppliers - **name:** Suppliers - **status:** live - **custom field support:** false - **downstream id:** product-tax-codes - **downstream name:** Product Tax Codes - **id:** tax-rates - **name:** Tax Rates - **status:** live - **custom field support:** false - **downstream id:** attachments - **downstream name:** Attachments - **id:** attachments - **name:** Attachments - **status:** live - **custom field support:** false - **downstream id:** trial-balance - **downstream name:** Trial Balance - **id:** trial-balance - **name:** Trial Balance - **status:** beta An omitted operation list does not establish operation support.
