Best practices with Microsoft Graph: Making your applications more performant, resilient, and reliable.
- 4. your Your app Gateway Your or your customer’s data Office 365 Windows 10 Enterprise Mobility + Security 1Microsoft Graph
- 5. Get to know the API
- 7. prepared
- 8. Graph uses server- side page size limits When querying collections, Graph may return the results in many pages Always expect an @odata.nextLink property in the response Contains the URL to the next page
- 9. 1. Always handle the possibility that the responses are paged in nature 2. Follow the @odata.nextLink to obtain the next page of results 3. Final page will not contain an @odata.nextLink property 4. Treat the entire URL as an opaque string
- 10. Error Best practice 403 How did this happen? My application got consent! The signed-in user does not have privileges to access the resource requested. Tip: Provide a generic "Access denied" error back to the signed-in user. 404 How did this happen? I just got this resource! Resource not yet provisioned (like a user's photo) Resource has been deleted Tip: Watch for restore - your application should also take this into account. 429 Your app should always be prepared to be throttled. Tip: Honor the HTTP Retry-After response header to recover Tip: Rate limit to stay below throttle limits 503 Service is busy Tip: Retry – but employ a back-off strategy similar to 429 Tip: Additionally, always make new retry requests over a new HTTP connection
- 11. Retry logic for transient errors
- 12. Storing data locally in your application required terms of service privacy policy retention deletion policies
- 13. Optimizations
- 14. Use projections GET ? $select=givenName,mail Choose the properties your app really needs and no more Don’t send unnecessary data over the wire Tip Use $select
- 15. Use filters GET ? $filter=department eq ‘Sales’ & $select=givenName,mail Choose the records your app really needs and no more Don’t send unnecessary data over the wire Tip Use $filter
- 16. POST/PATCH/PUT If your code doesn’t need to get a response, then opt out Don’t send unnecessary data over the wire Tip Use HTTP Prefer return=minimal request header
- 17. Webhooks Scenario Application needs to know about changes to data – like deleted users Tips Use webhook notifications whenever data of interest has changed Put notifications in a queue for later processing Why Avoid computationally expensive and excessive polling
- 18. Delta query Scenario Need to cache or store Microsoft Graph data locally, and keep that data up to date, or track changes to data for any other reasons Tip Use delta query Why Stop retrieving data your application already has! Minimizes network traffic Reduces the likelihood of reaching a throttling threshold
- 19. Webhooks Delta query Scenario Same scenarios as before, but if you need to optimize further… Tips Use webhook notifications as the trigger to make delta query calls Put notifications in a queue for later processing Why Difficult to figure out optimal polling interval THR2436 Barracuda Sentinel: Microsoft Graph powered AI for real-time cyber fraud defense
- 20. Batching Scenario Mobile client app needs to get signed-in user’s profile AND avatar Tip Use JSON batching Why Performance gains through multiplexing Save the application significant network latency Conserves connection resources Lower bandwidth consumption
