A developer program is the

manifestation of DX.

Operations

@ManfredBo15

Minimum API Operations

Access Control: authentication and authorization to identify the

originator of incoming traffic and ensure only

permitted access.

Rate Limits and Usage Policies: usage quotas and restrictions

on incoming traffic to keep loads predictable.

Analytics: data capture and analysis of traffic patterns to

learn how the API is being used.

@ManfredBo22

Metrics:

• Number of API calls (per API per time unit)

• Latency, availability, round trip

• Response/error types

• Activities of apps/developers

• Etc.

Make sure to measure the right things

in the right stages.

Wrap-up & Take-away

A scaling API program requires a lot more than a

technically well-working API.

API adoption in quantity or quality is mandatory.

DX is the key to adoption. Evangelists are key to DX.

The API operations’ key performance objectives are

designed to support adoption.

API Analytics give you the intelligence to steer.
