From their site: We're a progressive nonprofit whose core activity is providing e-advocacy tools to other progressive nonprofits for pennies on the dollar relative to the fees demanded by the private sector. In our capacity as service provider, we offer cutting-edge communication tools enabling our user organizations to do everything from sending mass e-mail blasts to taking donations online. The Democracy In Action HTML API allows advanced users of the DIA tools to build custom, off-site interfaces to the data stored in their DIA account. It accomplishes this through specially formatted HTML form elements, submitted via HTTP POST to a processor script on the DIA servers, which can write to the database or retrieve information from it. At this time the main supported functionality is for writing data (as for instance a new supporter sign up, or a donation) to the DB.
The following is a list of libraries from ProgrammableWeb's Library Directory that matched your search term. Although there many different interpretations of the word "library" among software developers, ProgrammableWeb adheres to a specific definition so as to clearly distinguish libraries from SDKs and frameworks in a way that will facilitate clean search results. In ProgrammableWeb's parlance, the term "library" is strictly used to describe a platform-specific software tool that, when installed, results in the provisioning a specific API. Conversely, SDKs are exclusively for consuming APIs and Frameworks are agnostic to specific APIs. If you think a library, SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
