"Looking for help with Constant Contact v3 API integration for automated email campaign deployment. We're trying to create and send campaigns programmatically, but getting authentication failures when posting campaign content with dynamic templates.
Basic contact management API calls work fine, but campaign creation requests return 403 errors despite having proper OAuth tokens. Need someone experienced with Constant Contact's API permissions and email automation workflows.
Seeking 2-3 hours remote troubleshooting to resolve the campaign deployment issues. Need functional by Friday for our marketing automation launch.
