Description
The Slack add-on forwards WS Form submissions to public and private Slack channels, mapping form fields into structured messages with a title, attachments, image, icons and up to four buttons with custom links. Connection to the workspace is established via OAuth 2.0 and triggers occur when the form is saved, submitted or both events, catering to teams that need to monitor leads, support or new registrations in real time within the conversation.

For teams that rely on Slack as a daily hub, this add-on turns each WS Form submission into a visible message in the right channel, with buttons and attachments that allow action without switching tools.
