MORE TOUCHPOINTS MORE SERVICES MORE APIs
Modern businesses are delivering
their services through an increasing
number and diversity of
touchpoints.
For example, retailers can sell products via
their e-commerce website, multiple mobile
applications for different operating systems,
third-party platforms and even physical
stores.
This increasing number of
touchpoints entails an increasing
volume and variety of IT services
and an increasing number and
diversity of interactions between
these services.
For example, all the touchpoints via which
retailers sell products must interact with the
product inventory.
This increasing number of
interactions entails a growing need
for APIs to enable a loose
coupling between services.
For example, retailers can use an API to
enable services to interact with the product
inventory.
APIs are effective to enable interactions between both internal and external
services, and can therefore play a significant role in business integration.
companies use more than 1,000
applications on average, 10%
more than last year2
99% of companies added at least
one new sales channel in 2022,
51 % added 3 or more1

capacity for each supplier
We established the performance characteristics of each
supplier thus giving our client visibility into which
supplier would deliver the level of service necessary to
support the client’s business and growth.
- Time savings
- Cost savings
- Peace of mind
- Guarantees for required level of service
Accelerator: Our API testbed
Our client had a short time to
market to deploy a new
payment clearing system.
Needing to choose between
several vendors, the client
needed to arrive quickly to a
recommendation.
They needed an
independent, apples to
apples comparison in order
to determine which vendor
would support their
expected growth and allow
them to capitalize quickly on
this new revenue source

● Solution 1 platform can hold high number of requests by second
● Solution 2 platform can also manage a large number of requests by second
● Solution 3 performance is limited with the configuration of the delivered platform
Solution 1 Solution 2 Solution 3
Performance test scenario is run for each solution. The results are presented graphically and a summary for the 3 solutions is presented in a table.
