Turn QuickBooks Online into a REST + MCP endpoint

Writ turns the QuickBooks Online actions you already do in a browser into a callable REST endpoint your software (and your AI agents) can call.

curl -X POST https://api.usewrit.app/v1/quickbooks/run \
  -H "Authorization: Bearer wt_8f2c...a91" \
  -H "Content-Type: application/json" \
  -d '{ "input": { "query": "your search term" } }'

Record the QuickBooks Online task once (open a report, then export invoices) and call it as a REST endpoint and an MCP tool. No backend project, no waiting on QuickBooks Online to ship an API.

1. 1
   Record the QuickBooks Online task once

   Open the recorder and open a report on QuickBooks Online in a real browser. Writ captures each step, including login and 2FA, into a reusable workflow.

2. 2
   Publish it as an endpoint

   One click turns the workflow into a callable REST endpoint at /v1/quickbooks/run and a matching MCP tool. Inputs become a typed schema.

3. 3
   Call it from anything

   Call QuickBooks Online from your code, a no-code tool, or an AI agent. Run it on your own machine for free, or on metered cloud.

Read the REST API docs, see what's possible on workflows, or search for another site. Free to start. See pricing.

QuickBooks Online has an API, but some reports, exports, and settings are only reachable through the browser UI.

Writ closes that gap. Record the QuickBooks Online task once (or describe it to an AI session) and publish it as a REST endpoint at /v1/quickbooks/run and a matching MCP tool. Writ runs on your own accounts, with your own credentials and data, on sites you are authorized to use.

Each operation below is a real QuickBooks Online action recorded into a workflow and exposed as a typed endpoint.

Returns structured fields such as invoice, expense, report value, balance: typed JSON, not raw page text.

POST your inputs, get structured output. Authenticate every call with a scoped wt_ key.

curl -X POST https://api.usewrit.app/v1/quickbooks/run \
  -H "Authorization: Bearer wt_8f2c...a91" \
  -H "Content-Type: application/json" \
  -d '{ "input": { "query": "your search term" } }'

import requests

r = requests.post(
    "https://api.usewrit.app/v1/quickbooks/run",
    headers={"Authorization": "Bearer wt_8f2c...a91"},
    json={"input": {"query": "your search term"}},
)
print(r.json()["output"])

{
  "run_id": "run_quic_7b21",
  "status": "succeeded",
  "output": {
    "invoice": "...",
    "expense": "...",
    "report_value": "..."
  }
}

The reason QuickBooks Online has no usable API is the same reason it's hard to automate. Writ handles it.

Writ signs into your own QuickBooks Online account through a Persona with 2FA and runs inside that authenticated session.

Pick whichever fits the task. All three produce the same callable workflow.

Built on the same engine as the recorder and workflows.

Monitor QuickBooks Online for report value change, new overdue invoice, balance threshold and fire this endpoint the instant something changes.

Monitors check as fast as every 10s (10s on Enterprise). A detected change becomes an automation trigger that runs your workflow in seconds. Monitor QuickBooks Online ▸
