Integrations & API

Connect OPEX to the systems you already use.

OPEX works with the technology behind property sales, contracts and settlements. Use built-in integrations with PEXA and Insite Logic, connect your practice, document and payment systems through tailored integration work, or build directly on the OPEX API.
