# Developer API There are 2 api sets, POESESSID and OAuth 2.0. ## Data Export The game data does not have any official API, and only possible data can be analyzed from the game files. Almost all data is stored in .dat64 files within Content.ggpk. But they only have data, no headers. You can start with the .dat64 format, the [PoE dat schema](https://github.com/poe-tool-dev/dat-schema) project is the latest format. Or try to parse the .dat format from [PoE Dat Viewer](https://snosme.github.io/poe-dat-viewer/) yourself. [RePoE](https://github.com/brather1ng/RePoE/) collects many common and processed .dat files and exports them to .json format.
