Sometimes, you may run into the “HTTP 429 Too Many Requests” error when a flow is triggered repeatedly in a short time when using the DocumentsCorePack (DCP) Connector. To counteract this, an “Exponential retry pattern” must be set.
Please note: The API Limits are a limitation from Microsoft.
Custom connectors (as our DocumentsCorePack Connector) are rate limited by Microsoft, so making too many calls in a short time will cause an error to occur between PowerAutomate and the DCP connector.
As this is unfortunately beyond our control, we recommend using the “Exponential retry pattern” offered by PowerAutomate. This will ensure that your flow does not retry several times within a very short period of time. Instead, the flow will pause between calls.
You will need to set the Retry Policy to Exponential Interval for this to work due to the limitations of request that Microsoft has imposed on all Connectors and not just the DocumentsCorePack Connector (Have a look at Retry Policy Exponential Interval Explanation). Setting this will allow the process to continue when it hits the limit after sending large jobs to Flow.
How to change the “Retry-Policy” in your Flow
Navigate to your DocumentsCorePack Connector in your Flow and hit the 3 dots. A selection window is shown. Select “Settings”.

This window opens. We recommend the following changes:
Type: Exponential Interval
Count: 20
Interval: PT10S
Minimum Interval: PT10S
Maximum Interval: PT40S
