@mj You can increase it upto 120 seconds using API. Here's an CURL request example for updating timeoutSeconds.

curl -X PATCH https://api.vapi.ai/tool/id \
     -H "Authorization: Bearer " \
     -H "Content-Type: application/json" \
     -d '{
  "type": "function",
  "server": {
    "url": "insert-your-server-url-here",
    "timeoutSeconds": 90
  }
}'
