This guide is full of simple, easy-to-follow instructions that’ll help you use Buildium’s API like a pro.
Before you can use Buildium’s API, you’ll need to make some tweaks to your account settings.
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.
Sign in to your Buildium account from your browser.
Open the Settings menu and click Application settings.
Under System preferences, click Api settings. A modal will appear.
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.

Account-level API keys authenticate every request and keep things secure.
API keys have two components: a “client ID” and a “secret”.
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!
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.
