What to build with Microsoft Graph?

Portal/mobile appsAutomation/business

process apps

Bots/dialogue apps Analytical apps

4 app patterns

Portals, desktop, and mobile apps

▅ Typically HTML+JavaScript,

iOS, or Android

▅ Always has authenticated

user

▅ Content tends to be user-

oriented and scoped

▅ Consider offline usage

scenarios

Automation and business process apps

▅ Variety of languages and

hosting options (e.g.,

serverless)

▅ Almost never has

authenticated user

▅ Content can range over

users and domains

▅ Consider batching and

throttling implications

Bots and interactive dialogue apps

▅ Typically framework based

(e.g., Bot Framework)

▅ Usually has authenticated

user (but auth is challenging)

▅ Content tends to be user-

oriented and scoped

▅ Consider how to render

result(s) with limited real

estate or “headless” devices

Analytic apps

▅ Typically involves big data

processing tools

▅ Never has authenticated

user

▅ Content tends to be broad

but specific (minimize

footprint)

▅ Consider security, privacy,

and ToU implications
