Welcome to Buildium’s API—a powerful, RESTful programming interface that lets you leverage valuable Buildium data.

Using HTTP requests, you can create integrations with applications that specialize in accounting, lead tracking, and more. Enjoy greater flexibility, transparency, and control over your business!

What's in this Guide?

This guide is full of simple, easy-to-follow instructions that’ll help you use Buildium’s API like a pro.

Topics include:

  • choosing the right resources for your use case
  • making HTTP requests to any resource
  • understanding data and response codes

Getting Started

Excited to get going? We’ll walk you through the setup process.

Account Configuration

Before you can use Buildium’s API, you’ll need to make some tweaks to your account settings.

Enabling the API

In order to start creating your keys and making requests, you’ll need to enable the API.

Tip: You’ll need an administrator user role with access to Application settings to set things up properly.

Let's Begin!

  1. Sign in to your Buildium account from your browser.

  2. Open the Settings menu and click Application settings.

  3. Under System preferences, click Api settings. A modal will appear.

  4. Click the Open API toggle to turn it on. Then click Save.

Congratulations! Your account's enabled. Now, you’re ready to start managing API keys.

If you are having issues enabling the API within your account you can submit a Support request for assistance.

API Keys

Account-level API keys authenticate every request and keep things secure.

API keys have two components: a “client ID” and a “secret”.

  • Client IDs are similar to usernames. They’re used to identify your Buildium account and are safe to share.
  • Secrets are similar to passwords. They must be kept confidential.

Whenever you make a request, you’ll need the API key’s client ID and secret. If you forget it, make a mistake, or try to use information that’s linked to a deleted key, the API will return a 401 response code.

Tip: We compiled a list of best practices that detail how securely store API keys. Give it a read!

Creating API Keys

Now that the Open APi is enabled, you’ll be able to create API keys. You’re almost there!

Tip: You’ll need an administrator user role to complete this step, too.

How to create an API key

  1. Sign in to your Buildium account from your browser.

  2. Open the Settings menu and click API Keys. The page will open automatically.

  3. Click Create API Key. A modal will appear.

  4. Enter a clear, memorable name and description for your API key. It’ll make it easier to locate the right key when you make a request. Once finished, click Next.

  5. Now, choose which pieces of Buildium data you want this API key to have access to by marking the corresponding checkboxes. Once finished, click Next.

  6. You successfully created an API key!

Important: This is your only chance to record the secret. Make sure it’s stored somewhere secure! If it’s forgotten, you’ll need to delete this key and start from scratch.

You have now successfully created an API key and have everything you need to send requests to the Buildium API!

Before moving on to making your first request please review Keeping your Keys Safe for an overview on securely storing your API keys.

If you are having issues creating API keys you can submit a Support request for assistance.

Keeping API Keys Safe

Based on their permissions, API keys could have full access to your account’s Buildium data. It’s important that you only grant access to trusted applications, securely record secrets, and consider a password manager to stay organized.

  • Avoid hard-coding client IDs and secrets inside source files.
  • Avoid storing client IDs and secrets in any files that may be committed to source control, particularly cloud-based source control platforms.
  • Apply restrictions to client IDs and secrets shared with your staff. You can restrict a key to particular Buildium entities or to read-only access (GET resources only).
  • Avoid sharing client IDs and secrets across public, insecure platforms.
  • Establish a process to regularly recreate your client IDs and secrets from your Buildium account.

How to Make a Request

You’ve done a great job setting up your account, Now, we’ll walk you through how to access your data. It’s very straightforward and should only take a few minutes!

Tip: Looking for the right HTTP client? If you’re just getting started, we recommend Postman.

Let's Get Started!

Step 1: Get Your API Key

If you haven't yet done so, obtain your API key client ID and secret from your Buildium account. Your API key is how the Buildium API authenticates requests and ensures only you can access your data.

See Getting Started for a deeper dive into enabling the API and creating keys.

Step 2: Install a HTTP client

The Buildium API supports any standard HTTP client. If you're looking for a user-friendly HTTP client application, we recommend Postman – it allows you to access the Buildium API without writing code. We’ll use Postman for our example below to demonstrate sending an API request.

Step 3: Make a Sample Request

Let's dive in and make a simple request to get all the Rental Properties in your account. This will confirm your connectivity to our platform and validate the keys you created on our website. Simply follow the instructions below.

  1. Open the Postman application.
  2. Open the verb menu and select GET.
  3. Enter the request endpoint in the field next to GET.
  4. To authenticate the request, enter your client ID and secret respectively in these request headers:
    • x-buildium-client-id
    • x-buildium-client-secret
    • Your full request should look similar to the image below.

  1. Review the parameters of your request on last time. Once finished, click Send.

  2. If successful, you should see a JSON response and a 200 HTTP status code. Voilà! You've connected to the Buildium API.

You now have the knowledge required to make requests for any of our resources.

If you've received an error response please review the JSON response message for a description of how to resolve the issue. You can also see more information about HTTP status codes in the Response Codes section. If you are still having trouble making a request after reviewing these sections please submit a Support request.

API Overview

The Buildium API is built upon standard REST conventions. It's designed to use consistent resource-oriented URLs, accept and return JSON-encoded messages, and use standard HTTP status codes and verbs.

Base URL

The base URL for production environment API requests is:

The base URL for sandbox environment API requests is:

In order to ensure all requests and responses are secure between the API consumer and Buildium servers, requests must be made using the https protocol. Any requests not made with the https protocol will be refused by the Buildium API platform.
