Update on Dynamics 365/CDS request limits

End of August Microsoft announced an API based limitation which is based on users and the type of licenses they have - the latest documentation is available on http://aka.ms/platformlimits  as well as PowerApps and Microsoft Flow licensing FAQs for October 2019. I would recommend regularly checking these pages as they have been updated quite a few times in the last months.

During interactions with Microsoft the last couple of months, they explained that the allocated number of API calls within the different licenses are based upon internal telemetry on the current Dynamics 365 customer base. The claim is that 95% of customers fall within the standard allocated API limits. But if you are using a lot of integrations, you might need to  re-architect part of your solution.

Listed below are the key takeaways:
  • Users with a Dynamics 365 Enterprise Application license have 20.000 API requests allocated in a 24 hour window.
  • Technical/non-interactive/application users get allocated 100.000 API requests if at least one Dynamics 365 API license is available.
  • If a user exceeds the limits the admin for the tenant/environment will receive a notification - end users will not be blocked from using the app.
  • This new licensing went into effect for new customers who on boarded after October 2019. Existing customers have a transition period until October 2020 or when their licensing contract expires. Whichever is longer. For customers with an enterprise agreement this will be the end of their EA (in most cases I know these contracts are valid for 3 years), customers on a CSP contract typically have a yearly expiration date. Reach out to your licensing partner or Microsoft for more details. 
  • The currently available statistics in the Power Platform Admin Center are still quite rudimentary but are a good starting point to assess the impact on your environment 
  • It is possible to purchase additional blocks of 10,000 daily API requests for $50 per month (For details reach out to your licensing partner)
  • Batch requests (Executemultiple) only count as 1 API call, so you can wrap a 1.000 individual calls in one ExecuteMultiple call.
