When you design your flows it is important to be aware of the Power Automate connector limits.
Power Automate Connector limits examples
In yesterday’s post I mentioned that I was hitting the limit of 600 API calls per minute for the SharePoint connector. This limit is a limit that is different for each connector. These connectors are available within Power Automate, Power Apps and Logic Apps or in any of these 3 applications.
After a bit of investigation work I found that each connector has a different limit. During the design of your flow systems this might be important to keep in the back your mind. Just to give you an example, the notification connector will only work 5 times during each period of 5 minutes. Did you ever miss any notification? Now you might know why.
It is not just the API call limit that is important. The trigger poll frequency also different for each connector. Did you know that the frequency of the triggers in the Microsoft forms trigger is only once a day!
To complete the overview of both the API call limit and the Trigger poll frequency I’ve built the table below.
[…] that may happen. To answer this question we need to look at these variables. In my post about triggers and their limitations I already found out that I’m limited to 600 calls every 60 […]
Does all these connectors use polling mechanism? Specifically for SharePoint, does sharepoint trigger polls for changes in SharePoint list?
some use triggers and some use webhooks.
Hi Pieter, I was wondering where I could find the latest info on the ‘trigger poll frequency’, specifically for the ‘File system’ connector? Also, is there any way for the Flow ‘creator’ the reduce the polling frequency and thus potentially reduce the load on the File servers? Hope things are well. Many thanks, Geraint
Hi Geraint,
You will find the throttling limits on the page below:

To reduce the number of calls made you could set the Concurrency control. You can find this on the triggers under Settings.
Hi Pieter,
I’m trying to understand “API call per connection” Is it based on per user? I’m using the Mail connector which is 100 calls in a 24 hour period. If I have 200 users using a Power App that submits a notification email through a Flow, does that count as 200 calls combined or is a connection associated with each user so each user has 100 API calls within the 24 hour period.
Hi Wesley,
It is 100 calls per user
Thanks Pieter!
