An API (application programming interface) is a set of routines, protocols, and tools for building software and applications.

Openaid.se uses the API from the  IATI Datastore, which you can find here: datastore.iatistandard.org/docs/api/. Through that API you can access all IATI data, not just the files from Sweden that we use on Openaid.se

You can read more about how the IATI Datastore works here: datastore.iatistandard.org/docs/, and there is a helpful user guide to be found here: datastore.iatistandard.org/docs/user-guide/.

There is also an API for the IATI Registry, which contains meta-data on files published in the IATI XML format. You can access that here: iatiregistry.org/registry-api
