# Rillet — Accounting API: overview > Canonical URL: https://developers.apideck.com/apis/accounting/rillet/overview Rillet is a modern accounting platform built for SaaS companies, providing automated revenue recognition, invoicing, and financial reporting. - Status: beta - Authentication: apiKey - **account type required:** A Rillet account. Any plan works; there is no edition gate on API access. - **apideck credentials available:** false - **apideck credentials note:** Each consumer connects with their own Rillet organisation API key; there is no app to register. - **authentication note:** Presented as a Bearer token in the Authorization header; not OAuth. Keys are scoped to a single Rillet organisation. - **beta:** true - **consumer access level:** Admin access to Organization Settings, which is where API keys are created. - **costs:** No API-specific fee. Rillet itself is a paid platform and does not publish pricing. - **difficulty:** moderate - **difficulty reason:** API Key Authentication + API Access Enabled per Organisation by Rillet - **environment notes:** - **description:** Purpose: development and testing against sandbox.api.rillet.com. Credentials: a sandbox API key created in that environment's Organization Settings. Access is arranged through your Rillet team, the same route as production API access — there is no self-service sandbox signup. - **environment:** Sandbox - **description:** Purpose: live financial data on api.rillet.com, using a production API key created at https://app.rillet.io/settings/api-access. - **environment:** Production - **description:** Sandbox and production API keys CANNOT be used against each other. The environment is selected when the connection is created in Vault, so a key and an environment that disagree simply fail to authenticate. - **environment:** Critical - **important to know:** API access is not self-service. Rillet has to enable it for each organisation before any API key can be created, so your consumer starts by contacting their Rillet team rather than by opening a settings page. - **partnership required:** false - **rate limits:** 60 requests per rolling one-minute window; requests above it return HTTP 429. - **responsibility matrix:** - **area:** Request API access from Rillet - **consumer:** ✓ - **customer:** Share instructions - **area:** Create the API key - **consumer:** ✓ (Organization Settings admin) - **area:** Choose the environment - **consumer:** ✓ (at connection time) - **apideck:** Securely stores credentials - **area:** Enter credentials in Vault - **consumer:** ✓ - **apideck:** Maintains connector - **area:** Build via the Unified API - **customer:** ✓ - **apideck:** Logs & alerts - **area:** Monitor connections - **consumer:** ✓ Can revoke the key anytime - **customer:** ✓ Via Dashboard - **sandbox available:** true - **sandbox note:** A separate sandbox environment at sandbox.api.rillet.com with its own API keys, arranged through your Rillet team. - **supported resource categories:** - **name:** Core Financial - **resources:** ledger-accounts tax-rates journal-entries company-info subsidiaries balance-sheet profit-and-loss - **name:** Accounts Receivable - **resources:** invoices invoice-items customers payments credit-notes - **name:** Accounts Payable - **resources:** bills bill-payments suppliers expenses - **name:** Banking - **resources:** bank-accounts bank-feed-statements - **webhooks:** No webhooks ## Supported resources [Accounting data model](/guides/accounting-data-model.md) - **custom field support:** false - **downstream id:** organizations - **downstream name:** Organizations - **id:** company-info - **name:** Company Info - **status:** live - **custom field support:** false - **downstream id:** charges - **downstream name:** Charges - **id:** expenses - **name:** Expenses - **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:** customers - **downstream name:** Customers - **id:** customers - **name:** Customers - **status:** live - **custom field support:** false - **downstream id:** vendors - **downstream name:** Vendors - **id:** suppliers - **name:** Suppliers - **status:** live - **custom field support:** false - **downstream id:** invoices - **downstream name:** Invoices - **id:** invoices - **name:** Invoices - **status:** live - **custom field support:** false - **downstream id:** products - **downstream name:** Products - **id:** invoice-items - **name:** Invoice Items - **status:** live - **custom field support:** false - **downstream id:** invoice-payments - **downstream name:** Invoice Payments - **id:** payments - **name:** Payments - **status:** live - **custom field support:** false - **downstream id:** bills - **downstream name:** Bills - **id:** bills - **name:** Bills - **status:** live - **custom field support:** false - **downstream id:** bill-payments - **downstream name:** Bill Payments - **id:** bill-payments - **name:** Bill Payments - **status:** live - **custom field support:** false - **downstream id:** credit-memos - **downstream name:** Credit Memos - **id:** credit-notes - **name:** Credit Notes - **status:** live - **custom field support:** false - **downstream id:** vendor-credits - **downstream name:** Vendor Credits - **id:** bill-credit-notes - **name:** Bill Credit Notes - **status:** beta - **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:** tax-rates - **downstream name:** Tax Rates - **id:** tax-rates - **name:** Tax Rates - **status:** live - **custom field support:** false - **downstream id:** balance-sheet - **downstream name:** Balance Sheet - **id:** balance-sheet - **name:** BalanceSheet - **status:** live - **custom field support:** false - **downstream id:** income-statement - **downstream name:** Income Statement - **id:** profit-and-loss - **name:** ProfitAndLoss - **status:** live - **custom field support:** false - **downstream id:** trial-balance - **downstream name:** Trial Balance - **id:** trial-balance - **name:** Trial Balance - **status:** beta - **custom field support:** false - **downstream id:** subsidiaries - **downstream name:** Subsidiaries - **id:** subsidiaries - **name:** Subsidiaries - **status:** live - **custom field support:** false - **downstream id:** bank-accounts - **downstream name:** Bank Accounts - **id:** bank-accounts - **name:** Bank Accounts - **status:** beta - **custom field support:** false - **downstream id:** bank-transactions - **downstream name:** Bank Transactions - **id:** bank-feed-statements - **name:** Bank Feed Statements - **status:** beta An omitted operation list does not establish operation support.
