What can the Rent Manager API do?
Rent Manager’s official customization page says its web API provides both read and write access to a Rent Manager Online database. The stated use is to collect live data, integrate outside software, build custom applications, and write new data back into Rent Manager.
The official technical overview describes a REST-style API. GET retrieves data. POST sends data that, depending on the resource, may be saved or used to perform work. DELETE removes data where the resource supports deletion. Every request requires an authentication token in its header. Those credentials belong in a secure server-side secret store, never in browser code, a public file, or a shared spreadsheet.
The documentation also says collection results may be paginated automatically when they contain more than 1,000 records. That matters for a large portfolio. A worker cannot assume one response contains every property, resident, transaction, or open item. It must follow the current pagination rules, handle errors, and prove that it did not silently skip records.
Rent Manager separately offers Open Access. The company describes it as comprehensive read-only views through a mirrored copy of the live Rent Manager Online database. That can be the safer answer for reporting, analysis, and exception detection because the worker can read without changing a production record.
Access is not one yes-or-no question
Confirm account eligibility, activation, credentials, current resources, available fields, supported methods, pagination, service limits, and the support process. Rent Manager’s public pages do not promise that every customer, resource, or method has identical access. The Map verifies the connection before a build is quoted.
