Podio is built upon an API. Developers can use our API to integrate other services with Podio (or the other way around). The documentation of the API can be found at http://developers.podio.com. This site also showcases some of the possibilities with the API, the client libraries used and tutorials.
If you're a developer and have a technical question about the API, please post the question to Stack Overflow. Both Podio crew members and other skilled developers are there to assist you!
Note Remember to check already posted questions, your question might be answered already :)
Please note: At present we do not have a way to switch the API Client from one user to another.
