Hello!
Yes: https://github.com/GeoDirectory/geodir_api
It’s a plugin, and you install it like any other plugin.
Even more information:
https://wpgeodirectory.com/support/topic/rest-api-for-ios-and-andriod/
All the routes are documented at links available from the github repo.
There is also a dedicated forum. I will move this post into that forum.
https://wpgeodirectory.com/support/forum/geodirectory-core-plugin-forum/geodirectory-api/
We are quite happy to continue to provide documentation for the API. It is most definitely the preferred way to interact programmatically with GeoDirectory and GeoDirectory data.
Feel free to open more issues in this forum as you go along with your specific questions.
We look forward to seeing what you build!
