Canopy API Opens Platform to Accounting Firms
Canopy has launched a new external API giving accounting firms read and write access to core practice management records.
Canopy, the Utah-based practice management software provider, has launched the Canopy API, a new external interface that lets accounting firms connect its platform to the other tools in their technology stack. The API, announced on Sept. 30, gives firms read, create and update access to core practice records, allowing them to build internal portals, reporting dashboards and custom automations that run on live data.
The release extends a platform that already combines client relationship management, workflow, document management, time and billing, and payments in a single system. Canopy said the new interface is designed to let firms share core data and workflows securely with outside systems rather than keeping that information inside a single application.
“We have built an all-in-one system, but that does not mean we are a closed system,” said Hanna Bjornn, senior vice president of product at Canopy.
Bjornn pointed to custom reporting and automated client onboarding as two of the uses the company expects firms to build. The API is the first route for firms to do that work directly against the platform’s core records.
“Firms need the flexibility to pull their data into custom reporting dashboards or automate their onboarding workflows without running into roadblocks,” Bjornn said. “Our new API gives firms the access they need to build custom solutions and securely connect with the specific tools they use in their firm.”
The Canopy API covers clients, contacts, custom fields, tasks and client requests, with full create, read and update functions for client and contact records. Firms can also create documents and organise files through the interface, and Canopy’s developer documentation describes document access as write-only, intended for routing files from external systems into the platform. Custom fields can be defined by type and have their values read and written programmatically.
Canopy said write access to client requests sets its offering apart from competing practice management platforms, which the company says restrict many comparable objects to read-only access. Client requests are the mechanism firms use to collect documents and information from clients, and write access means external systems can open and update those requests directly rather than only reporting on them.
Billing and time data are next on the roadmap. Canopy’s API documentation lists invoices, payments, time entries, expenses and service codes as coming soon, which would extend the Canopy API from workflow and client records into the financial side of practice management.
Access to the Canopy API is tied to subscription tier. Customers on the Plus plan can connect client and contact information, while the Premium plan unlocks full API access. Developers can find documentation and onboarding material through a dedicated developer portal at portal.dev.canopytax.com.
Authentication runs through API keys generated in the platform’s administrative console, and the interface uses each firm’s existing Canopy identity and permission settings. The company says the API is built on the same system of record as its core product, with per-tenant isolation and audit logging on financial calls. Canopy states that it holds SOC 2 Type II certification, is GDPR compliant and uses 256-bit encryption for data in transit and at rest.
The launch also sets a timeline for older integrations. Canopy says its legacy external API is targeted for retirement in 2027, and that customers will receive advance notice of breaking changes before the switch.
Alongside the API, Canopy is building a server based on the Model Context Protocol, an open standard that lets AI assistants connect to outside software. The company said the server will allow assistants such as Anthropic’s Claude to link directly to Canopy, so users can look up client information and complete tasks through natural language requests.
The MCP work follows Canopy Coworker, an AI execution layer the company introduced earlier this year. Canopy describes Coworker as a system that carries out multistep tasks across its CRM, document management and billing modules, including client onboarding, document follow-ups and capacity planning, within guardrails and permissions set by each firm.
Existing ready-made integrations remain in place for firms that do not plan to build their own connections. Those include Filed, Juno, Google Calendar and Zapier, the last of which lets firms link Canopy with other applications without writing code.
The Canopy API is aimed at firms with in-house technical capability or access to developers, according to the company’s documentation. Canopy lists use cases including synchronising practice data with a data warehouse, connecting to internal business systems and routing documents from outside applications into client files.
For Canopy, the API and the forthcoming MCP server form two routes into the same platform. The Canopy API serves firms building direct integrations and automations, while the MCP server is intended to give AI assistants access to the same practice data through conversational requests.
