Geotoko is a platform that allows brands, businesses and agencies to create their own branded location-based promotions (e.g. sweepstakes, contests, give-aways) and to simultaneously publish them on multiple location-based services like foursquare, gowalla, facebook places, yelp, twitter etc. An API key is required for use. Users can search by location(latitude, longitude and radius) or by foursquare and gowalla IDs. This API (beta) provides access to Geotoko campaign data via HTTP requests and returns all data in JSON format.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
