Schedules and webhook triggers come with the paid plans, from $29 a month. ## Once built, one call from your code Once you have built a [method](/product/methods), it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get unpaid bills by property” would look like. Example request: ``` curl https://api.fous.com/v1/runs \ -H "Authorization: Bearer $FOUS_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "method": "signin.managebuilding.com/get_unpaid_bills_by_property", "input": { "properties": "All properties", "as_of": "2026-11-12" } }' ``` Example response: ``` { "status": "completed", "data": { "as_of": "2026-11-12", "properties": [ { "property": "Northwind Court", "property_balance": 18240.55, "bills": [ { "vendor": "Acme Plumbing", "amount_due": 1450, "aging": "31-60 days" } ], "unused_credits": 0 } ], "total_due": 2070, "count": 2 } } ``` An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request. ## Buildium’s own options Buildium's Open API is part of the Premium plan, which Buildium lists from $420 a month. An administrator turns it on in the account's API settings and creates account-level keys, and Premium includes a free sandbox account. Without Premium you work in the browser, with reports in PDF, XLSX or CSV and the Export Data files. | Option | What it covers | What it takes | | --- | --- | --- | | Open API | Accounting (bank accounts, bills, budgets, general ledger), resident and to do requests, work orders, vendors, inventory and assets, plus webhooks. | Premium plan, from $420 a month.

With Fous you sign in through Buildium's own sign-in with your own account, the login is sealed with AES-256, and a method reads and does only what your user can. ## Worth knowing - **The Open API is a Premium feature**: An administrator with access to Application settings turns on the Open API under API settings, then creates keys. Keys are account-level: a client ID and a secret sent in two request headers. - **Recurring tasks appear overnight**: Recurring tasks are created once a day by an overnight batch process, so a morning schedule sees that day's recurring tasks. - **Batched reports wait and then expire**: A batched report can take a few minutes to generate, with an option to email you when it is ready. It stays in Recently batched reports for 24 hours only. - **A resident request notifies the resident**: When staff add a resident request or a rental owner request, Buildium automatically sends a notification to that resident or owner that the task was created. ## More in Real estate: property management and listings - [レインズ](https://fous.com/automate/reins.md) - [HomeWiseDocs](https://fous.com/automate/homewisedocs.md) - [Bright MLS](https://fous.com/automate/bright-mls.md) - [CRMLS](https://fous.com/automate/crmls.md) - [Flexmls](https://fous.com/automate/flexmls.md) - [Matrix](https://fous.com/automate/matrix.md) - [Paragon MLS](https://fous.com/automate/paragon-mls.md) - [Ignite](https://fous.com/automate/ignite.md) - [PF Expert](https://fous.com/automate/pf-expert.md) - [Rightmove Plus](https://fous.com/automate/rightmove-plus.md) - [ZooplaPro](https://fous.com/automate/zooplapro.md) - [AppFolio Property Manager](https://fous.com/automate/appfolio-property-manager.md) - [Entrata](https://fous.com/automate/entrata.md) - [PropertyMe](https://fous.com/automate/propertyme.md) - [Yardi Voyager](https://fous.com/automate/yardi-voyager.md) - [Rental Bonds Online](https://fous.com/automate/rental-bonds-online.md) - [RTBA Online](https://fous.com/automate/rtba-online.md) - [ShowingTime](https://fous.com/automate/showingtime.md) - [Deposit Protection Service](https://fous.com/automate/deposit-protection-service.md) - [Tenancy Deposit Scheme](https://fous.com/automate/tenancy-deposit-scheme.md) Other industries: [KinderConnect](/automate/kinderconnect), [myUNFI](/automate/myunfi), [REWE Group Supplier Portal](/automate/rewe-group-supplier-portal), [TD SYNNEX ECExpress](/automate/td-synnex-ecexpress), [Checkatrade](/automate/checkatrade), [Nalanda](/automate/nalanda). ## Frequently asked questions ### Does Buildium have an API? Yes, on the Premium plan, which Buildium lists from $420 a month. The Open API covers accounting, resident and to do requests, work orders and vendors, plus webhooks, with account-level keys an administrator creates. Without Premium you have reports in PDF, XLSX or CSV and the Export Data files. ### How do I export my data from Buildium? Go to Settings > Export Data and pick the file you need. Files cover Rentals, Associations, Accounting, Tasks and Communication as .xlsx, and every report can also be run as XLSX. Buildium does not provide export files for all ledger financials. ### Can I see which vendor bills are overdue across all properties? Yes, with the Unpaid Bills by Property report under Reports. It lists unpaid bills and unused credits by property as of a date, split into 1-30 days, 31-60 days and over 60 days, for all properties or the ones you select, and downloads as PDF, XLS, XLSX or CSV. ### Is there a Buildium sandbox for testing an integration? Yes, for Premium subscribers. The sandbox is a separate account with realistic sample data at apisandbox.buildium.com, so tests do not touch your production data. ### Is Fous affiliated with Buildium? No. Fous is an independent product. You use it with your own Buildium account, and a method reads and does only what that account can. Fous is an independent product: it is not affiliated with, endorsed by or sponsored by the operator of Buildium (Buildium (RealPage)). The name is used only to say which system this page is about.
