The TransloadIt PHP Sample Code by TransloadIt demonstrates how to interact with the API. Plugin and template allow developers to initiate projects that require file uploading, conversion, and processing for websites/apps.
Transloadit offers media upload, modification, and storage as a service for developers who need that functionality (or, as Transloadit's homepage puts it, "geeks who run web or mobile applications") but don't want to worry about it themselves. There aren't too many moving parts to it, but they're ones a lot of applications make use of. The Transloadit API's main functions include: file upload, image resizing, video file encoding, image thumbnail creations, and file storage on Amazon S3.
