Managing
APIs
๏ An
API
is
a
business
capability
delivered
over
the
Internet
to
internal
or
external
consumers
๏ Network
accessible
func'on
๏ Available
using
standard
web
protocols
๏ With
well-‐defined
interfaces
๏ Designed
for
access
by
third-‐par'es
๏ A
Managed
API
is:
๏ Ac'vely
adver'sed
and
subscribe-‐able
๏ Available
with
SLAs
๏ Secured,
authen'cated,
authorized
and
protected
๏ Monitored
and
mone'zed
with
analy'cs

9. Communica'on:
Key
to
Dev
team
success
Teams
re-‐build
rather
than
re-‐use
• APIs
proliferate
(100s
of
APIs)
and
are
minimally
re-‐used
• Minimal
communica'on
and
coordina'on
• Who
is
consuming
API?
• Who
is

re-‐usable
APIs?
• Prevalent

• Not

• Shared

• Teams
do
not

about
API
• Non-‐func'onal

requirements
are
not
well
documented
• Teams
can
not
easily

Collabora've
Store
๏ Ability
to
create
mul'ple
domains
(tenants)
within
the
same
API
Manager
instance
๏ Each
domain
can
have
their
own
store
or
publish
APIs
to
a
central
store
-‐
This
is
transparent
to
the
consumers.
๏ Typical
Use
Cases:
๏ Segmen'ng
the
publishers
by
business
unit
or
partner
and
restric'ng
edi'ng
rights
by
domain
๏ Create
an
API
marketplace
:
one-‐stop
store
for
domain
APIs.

Visibility
๏ At
publish

an
API
can
be
marked
as
Public
or
Restricted
๏ If
Restricted
by
Roles
๏ 1
or
more
roles
need
to
be
specified.
๏ If
Restricted
by
Domain
๏ APIs
are
only
visible
to
specific
domain(s).
๏ Public
APIs
are
shown
to
all,
Restricted
are
only
visible
when
you
log-‐in
and
have
the
required
role
or
logged
in
to
required
domain.
23. Programing
Model
๏ Client
apps
(Web,
Mobile
etc)
to
call
the
API
๏ Those
calls
to
be
authen'cated
using
access
tokens

Tokens
๏ OAuth2
standard
compliant
๏ Pre-‐generated
Access
Token:
can
be
used
from
an
applica'on,
to
iden'fy
the
applica'on
itself
๏ On-‐demand
Access
Token:
generated
via
API
call,
using
Consumer
Key
and
Consumer

-‐
Iden'fies
the
end

of
an

(web

Shared
Access
Token
1. Project

for
the
APIs
by
login
into
the
API

2. API
Store
provides
a
access-‐token,
consumer-‐key,
consumer-‐secret.
๏ in
development
use
the
access-‐token
for
sandbox
environment.
3. Project
manager
shares
the
access-‐token
with
the
app-‐
developers.
4. App-‐developers
use
the
access-‐token
to
invoke
the
apis.
5. Project
manager
redistribute
new
access-‐token
when
it
expires
or
set
it
to
never

3. Project
manager
share
the

4. Each
app-‐developer
request
for
a

using
base64
encoded
value
of
consumer-‐key:consumer-‐secret
and
his/her
creden'als
(stored
in

using

๏ app-‐developers
can

using
a
valid
consumer-‐key,
consumer-‐secret
and
ac've
user
account
in
the
system

5. API
Gateway
return
a
access-‐token.
6. App-‐developers
invoke
the
