Field Mapping

All form fields are automatically included in the Slack message. Field names are displayed as labels, and values are shown below each label.

​
Troubleshooting

  • Verify the webhook URL is correct
  • Check that the Slack app is still installed in your workspace
  • Ensure the channel still exists
  • Try regenerating the webhook URL
Create a new webhook URL for the correct channel and update it in Spike.
Slack allows ~1 message per second per webhook. High-volume forms may experience delays.
