Limitations of "SP.MoveCopyUtil.CopyFileByPath" API in SharePoint 2019

Question

Hello everyone,

I'm encountering some issues while using the SP.MoveCopyUtil.CopyFileByPath API in SharePoint 2019. I need to copy 36 files, but the API calls stop after executing 30 times without any error messages. I'm wondering if there's a default limit on the number of API calls or any other factors that might be affecting this operation.

Here are the specifics of my situation:

• I am using SP.MoveCopyUtil.CopyFileByPath to copy files from one path to another.
• I checked for errors after each call, but no error messages were returned.
• After 30 API calls, the operation stops, and the remaining files are not processed.

I have reviewed my code logic and did not set any call limits. I understand that SharePoint might have some internal throttling mechanisms, but I couldn't find specific details on the limit values or configuration methods.

Does anyone know if SharePoint 2019 has a limit of 30 API calls per minute? Or do you have any suggestions on how to resolve this issue? Any help would be greatly appreciated!

Thank you!

Hi @Lee, Jason J

SharePoint Connection throttle limit of 600 APIs call per minute. 30 APIs call shouldn't getting throttled or blocked. You could refer to the following document which list all limitation
