Power Automate Retry and Timeout Policy
Whenever we are creating a flow, we might have encountered that a connector keeps sporadically failing due to some request issues or server-side errors in which the server fails to fulfil an apparently valid request. We can fortunately tackle these issues by setting up the retry policy for the connector. A retry policy applies to intermittent failures, characterized as HTTP status codes 408, 429, and 5xx, in addition to any connectivity exceptions. The default is an exponential interval policy set to retry 4 times. It is a good practice to set a retry policy for sending http requests and for Create, Update, Delete actions for Dataverse or any other service like SharePoint or SQL.
|
Error Code |
Description |
|
408 |
Request Timeout |
|
429 |
Too many requests |
|
5xx |
500 – Internal Server Error 503 – Service Unavailable 522 – Connection timed out, etc. |
For demonstration, I’ll configure a flow for creating a record in Dataverse and set the connectors retry policy.
Click on the three dots menu of the action and select Settings.
We see a retry policy setting which is set to Default.
Here is a table listing all the settings and their descriptions.

Retry Policy |
Description |
|
Default |
The default is an exponential interval policy set to retry 4 times. |
|
None |
Do not retry if failed. |
|
Fixed Interval |
Count - Number of times to retry. Interval - Time between retries. |
|
Exponential Interval |
Count - Number of times to retry Interval - Time between retries Minimum and Maximum Interval - the retry will happen exponentially (Increase or decrease) between the specified intervals. |
In fixed interval policy, we must specify Count, which is the number of retries before failing the flow and Interval, specified in ISO 8601 format, which requires us to set the time between retries, e.g.: PT20S means 20 seconds, PT5H means 5 hours, etc.

If Interval is PT1H and minimum Interval is set to PT1M - it will decrease exponentially till it reaches 1M. Conversely, If Interval is PT1H and maximum Interval is set to PT10H - it will increase exponentially (1-2-4-8-10) till it reaches 10H.
