I am working with the Webhooks in a Hubspot workflow. When I create a new workflow with the enrolment criteria I get about 40 contacts. In the workflow there is a webhook that goes out to our website api (PHP) and saves some data to the user. Once I start the Workflow though it sends all 40 requests right away which overloads the server we have. Is there any way to limit the timing between it sending them all at once?
