We Can Setup a Contract If You Want Maintainance
Podio crossed the integer threshold around June 30, 2022. They don't support their Java library, and my client couldn't upgrade to this one (you should try this first): https://github.com/OvalUK/podio-java, since this guy maintained a BUNCH of stuff. However, he upgraded tons of other dependencies, so this might not work for you. If you ONLY need/want the integer-to-long conversion, try this library, since the Podio Provided one will not work, and they will be unable/unwilling to provide you with support.
This is the Java client for the Podio API. Detailed documentation for the API is available on https://developers.podio.com. There you will find details on how to create an API key and use the API.
An introduction to the Java client is also available at https://developers.podio.com/clients/java
