Issues with Waterfall Integration: Awaiting Callback Delay

Hi team -- I'm unable to run my waterfall because I'm getting an "awaiting callback" message, and it's been 3-4 hours since I ran the table. Now the integration isn't running and showing this message. On top of that, I'm unable to run my other integrations due to this integration's response, even though I have enough credits in my Icypeas account. https://app.clay.com/workspaces/223519/workbooks/wb_KwXmhkap8BzU/tables/t_ckiBexTYbEVV/views/gv_vSJ38T36JhhY
