API & DEVELOPER ACCESS
Build on Accoru. Connect Anything. Automate Everything.
Accoru's REST API gives developers full programmatic access to every major platform function — invoices, clients, expenses, payments, reports, and more. Build custom integrations, automate financial workflows, and connect Accoru to any internal or third-party system your business runs on.
Built for Developers. Designed for Business.
Most small businesses will never need to touch the Accoru API — the native integrations with Stripe, PayPal, Shopify, and Zapier cover the majority of use cases without any code required. But for businesses with custom technical requirements — a proprietary billing system that needs to sync with accounting records, a custom client portal that needs to generate invoices programmatically, a data pipeline that needs to pull financial reports automatically, or a workflow that Zapier cannot handle — the Accoru API provides the full programmatic access required to build exactly what is needed. The Accoru API is a standard REST API — familiar to any developer who has worked with modern web APIs. It uses OAuth 2.0 for authentication, returns JSON responses, follows RESTful conventions, and is fully documented with examples for every endpoint. Building on Accoru is straightforward for any competent developer.
What You Can Build With the Accoru API
Full programmatic access to every major Accoru function — with consistent, predictable endpoints and comprehensive documentation.
Getting Started With the Accoru API
From zero to first API call in under 10 minutes.
- Step 1
Generate Your API Key
Log in to your Accoru account, go to Settings → API, and click Generate API Key. Name the key, select the permission scopes it should have access to, and copy the key. Store it securely — it will not be shown again after generation.
- Step 2
Read the Documentation
Visit the Accoru API documentation at docs.accoru.com. Read the authentication guide and make your first test request using the live API explorer — no code required. Confirm the API responds correctly with your credentials before writing any integration code.
- Step 3
Build in Sandbox
Switch your API key to sandbox mode and build your integration against the sandbox environment. Test every scenario — successful requests, error handling, webhook delivery, edge cases. The sandbox mirrors production exactly so confidence in sandbox equals confidence in production.
- Step 4
Deploy to Production
Switch your API key to production mode and deploy your integration. Monitor the API access log and webhook delivery log to confirm everything is working correctly. Rotate your API key if it is ever compromised — revocation is instant.

What Developers Say About Building on Accoru
“The Accoru API documentation is the best I have seen from an accounting software provider. Every endpoint is documented clearly with examples, the sandbox works exactly like production, and the webhook delivery is rock solid. We built our integration in two days.”
“We needed to sync our subscription billing system with our accounting records automatically. The Accoru API made this straightforward — the Invoices and Payments endpoints are clean and predictable, the webhook events fire reliably, and the OAuth implementation is standard. No surprises.”
“We pull financial data from Accoru into our data warehouse every night using the Reports API. The response structure is consistent, the pagination works correctly, and the data is always accurate. It has become a core part of our financial data pipeline.”
API & Developer Access FAQ
Is API access available on all Accoru plans?
Yes. API access is included in every Accoru plan at no additional cost. Generate your API key from your account settings and access the full documentation at docs.accoru.com.
What authentication method does the Accoru API use?
The Accoru API uses OAuth 2.0 with Bearer token authentication — the industry standard for secure API access. Generate API keys with configurable permission scopes from your account settings.
Is there a sandbox environment for testing?
Yes. Every Accoru account includes a fully isolated sandbox environment that mirrors the production API exactly. Build and test your integration in sandbox with no impact on your live financial records.
Does the Accoru API support webhooks?
Yes. Accoru supports webhooks for real-time event notifications — covering invoice events, payment events, quote events, client events, and expense events. Configure webhook endpoints from your account settings and Accoru delivers HTTP POST requests immediately when each event fires.
What rate limits apply to the Accoru API?
Accoru applies rate limiting to protect platform stability while providing generous thresholds for legitimate use. Rate limit information is included in every API response header so your integration can monitor its usage in real time. Contact the Accoru developer team if your use case requires higher rate limits.
Can I restrict what each API key can access?
Yes. Each API key is created with configurable permission scopes — so an integration that only needs to create invoices can be restricted to invoice write access only, with no access to expense data, reports, or other resources. Scopes can be modified and keys can be revoked at any time.
What programming languages are supported?
The Accoru API is a standard REST API that can be called from any programming language that supports HTTP requests. The documentation includes code examples in JavaScript, Python, PHP, and Ruby. Client libraries for additional languages are on the roadmap.
Where can I find the API documentation?
Complete API documentation is available at docs.accoru.com — including the full endpoint reference, authentication guide, webhook documentation, code examples, and a live API explorer for making test requests directly from the documentation.
