Enable aSync on Web Service Calls
You may need to enable the aSync parameter on web service calls to Blackbox Connector when moving significant amounts of information to avoid seeing timeout errors from your Vision server. This parameter allows the call to continue to run in the background while releasing your session, and should be set as described below if you see an “Operation Timed Out” error. This applies to:
Vision Connector for Constant Contact/Mail Chimp
Populate List Method for pushing contacts or updating contacts from Vision Marketing Campaigns
Retrieve Statistics Method for retrieving email campaign statistics.
Step 1: Launch Vision
Step 2: Navigate to Configuration > Workflows Scheduled Workflows
Step 3: Select Marketing Campaigns from the drop down list, and select one of the workflow Events labeled No ASync
Step 4: Find the Web Service Action you want to enable aSync on, click on the hyperlink, find the aSync parameter, and change to ‘true’.
