• API-enabled Platform Economy
• Importance of APIs for Singapore’s Smart Nation
• Exposing and consuming APIs
#ISSLearningDay2018

3. What is an API?
• An application programming interface (API) is a well-defined
method of communication between software
• APIs are used between applications (private, partner or public
sharing)
• APIs are used between parts of one application
• We use APIs whenever we use apps like Facebook, maps,
weather or travel booking

• Salesforce.com generates 50%
of its revenue through APIs,
Expedia.com 90% and eBay
60%
• Existing data and functionality
in IT systems can be monetized
via APIs

9. APIs are essential to the Digital
Economy in Singapore
• Singapore government app
OneService app is a one-stop
destination to report any
municipal issue
• The ‘whole-government’ API lets
data flow easily within and
between agencies, and between
the government and the public
• Uses API gateways to manage
the interactions

data.gov.sg
#ISSLearningDay2018
• Public government data is offered at
data.gov.sg
• The data can be consumed by developers
via APIs
• New products and services can be created
• 14 real-time APIs, e.g., car park and taxi
availability, weather, pollution, etc.

APIs, e.g., real-time bus arrival
information

16. Exposing and consuming APIs
#ISSLearningDay2018
Back-end
exposes APIs to
consumers
A front-end
developer uses
(consumes) the
APIs within their
application

17. How to use the DBS Bank APIs (1 / 3)
• Register for an account
• Activate the account by clicking
on the link in the email
• Select the API of interest
#ISSLearningDay2018

18. How to use the DBS Bank APIs (2 / 3)
• View the
documentation on
the API of interest
• Review the sample
request and
response

products/documentation/1

19. How to use the DBS Bank APIs (3 / 3)
• Try calling the API in the DBS ‘sandbox’ playground
- A safe environment to experiment with DBS APIs without affecting anything
• Register the application using the DBS Developer Portal
• Write the application and consume the APIs
- Register your application
- Get a client ID and client secret key for security
- Request the Auth Code from the DBS API Gateway
- Request the Access Token from the API Gateway
- Call the APIs
- Check the response
- If all is good, contact DBS team to request live access to the API
