SPD Workflow triggers multiple calls to the rest service

Question

I have a Sharepoint 2013 Designer workflow that calls the REST service on just 'Item created' . Rest service ZIP large size files. when i call the service from the workflow , IIS trigger the service multiple times if it does not receive the response in 40-50 secs that result in concurrent IO operations

I have tested the service independently , it works fine but does not work with the workflow.

To test my point , after the workflow triggers service first time. i stopped IIS and it worked fine so it is the IIS that is trigger the service multiple times depending on the size of the file.

How can i prevent the multiple calls

Answer 1

According to your description, it should be that the workflow waited too long for the response, and automatically requested the Rest again.
You could try to reset some attributes related to the workflow manager's HTTP request, such as WorkflowServiceMaxHttpResponseTime,WorkflowServiceMaxHttpRetryDelay.
You could refer to this issue to set the workflow manager:https://sharepoint.stackexchange.com/questions/95614/how-to-change-timeout-for-httpsend-activity
