Send form submissions to Slack
Send Formserve submissions to Slack channels for sales, support, or operations without building a custom backend.
How it flows
One POST to Formserve, delivered to Slack.
Post the form once to Formserve. Formserve stores the lead, applies spam checks, then sends a formatted message to the Slack webhook attached to that endpoint.

Slack webhook returns 4xx
Regenerate the incoming webhook in Slack if the old URL was revoked or belongs to the wrong workspace.
Message arrives in the wrong channel
Create a separate webhook per channel and attach the correct one to each Formserve endpoint.
Team needs more context
Include company, phone, or plan_interest in the form so the Slack payload is actionable.
