Started to receive 429 errors when posting data from Azure Logic App to Dynamics 365 Finance & Operations

Hi all,

We have developed a custom logic app that creates records in D365 Finance and Operations on request. The logic app has been working fine since deployment in in July 2021; however, from yesterday, we have begun to receive many 429 errors when attempting to post data to D365 Finance and Operations:


We have read the link provided and checked the metrics, but the values of ‘Trigger throttled events’ and ‘Action throttled events’ have been stable for the logic app over the past 30 days, indicating that the throttling is likely coming from the connector or D365 system itself:


The documentation link provided also does not provide any information as to why this would happen when the deployment has been stable for a long time previously. Could there be any possible reasons why this issue can suddenly occur and recur frequently over the span of ~24hours, and what are the possible means we could take to rule each scenario out? Thanks!

    @Jun Ting Ho Can you please confirm if you are using the same connection for all the Dynamics 365 Finance & Operations in same/different logic apps. In case if there are mutiple operation that you are performing or running parallelly then you could observe 429 error from the connector. The suggestion would to create multiple connections and distribute them through the app.
