From their site: Use Gastus to keep track of your daily expenses. When you're using the API, it's always through an existing user in Gastus. So when you use the API as "john", you get to see and work with what "john" is allowed to do. Pretty much any URL in Gastus can be viewed in its XML form by adding the .xml extension. So /expenses/4 becomes /expenses/4.xml. You can view, create, update, and delete resources through the API.
The following is a list of SDKs from our SDK directory that matched your search term. Though your definition of an SDK may differ, in our world, we define SDKs as platform- specific tools for consuming existing APIs of the sort we list in our API directory. For example, the Ruby SDK for consuming the Twitter Ads API.
