4. What is an API?
‣ “Application Programing Interface”
‣ Graphical User Interface (human to computer) vs.
Application Programming Interface (computer to
computer)
4
‣ APIs allow two computers to
interact with each other by passing
data and commands

5. What’s So Great About APIs?
‣ Design workflows that suit your
business needs
‣ Automate repetitive manual tasks (esp.
at scale)
‣ These reduce:
– Cost
– Labor hours
– Organizational and workflow complexity

8. How Does 3Play Media’s API Work?
‣ RESTful architecture
– Create, read, update, and destroy
(CRUD) information stored in the app
– For example, Facebook
8
‣ Not all CRUD is accessible via the API
‣ Not all functionality from the 3Play Media account
system can be accessed via the API

9. What can I do with 3Play Media’s
API?
‣ Manage caption/translation/alignment jobs
– View media resource information
– Request captioning, translation, or alignment
– Download finished captions and transcripts
‣ Add interactive transcripts to your video
Captions Subtitles Transcripts Alignment Interactive

10. How to Use the 3Play Media API
‣ Getting started:
– Create an API collection
– Retrieve the API key of the relevant collection
– HTTP requests
‣ 3Play Media terminology:
– Account
– Project
– Collection
10

11. How to Use the 3Play Media API
‣ Media resources are grouped in “collections”
‣ Specify folders in project that belong to a collection
‣ API key and API secret key for each collection
11

12. How to Use the 3Play Media API
‣ API key is a random string of characters that
identifies you to the system (like a password)
‣ Some calls only require the API key. Others require
the API key and the API secret key
12

13. HTTP Requests (CRUD)
Create – POST
Read – GET
Update – PATCH
Destroy – DELETE
13

14. View Files
‣ View all files in the collection:
– GET http://api.3playmedia.com/files
– Include apikey parameter
– http://api.3playmedia.com/files?apikey=abc123
‣ View a single file:
– GET http://api.3playmedia.com/files/:id
– Include apikey parameter
– http://api.3playmedia.com/files/123?apikey=abc123
