Slack notifications
Deliver accepted form submissions to a Slack channel through an incoming webhook.
Slack form notifications
Receive website leads and form messages in Slack.
Send accepted static-site form submissions to a Slack channel without building and operating your own form backend or custom Slack integration.
Submission delivery
Static website
Your site submits the form to its PostMyForm endpoint.
PostMyForm
PostMyForm validates and processes the submission.
Accepted submission
Eligible accepted submissions continue to configured delivery channels.
Slack and/or email
An active Slack destination can receive the submission independently of email delivery.
Form delivery without another backend
Put accepted submissions where your team already works.
Email stays independent
Slack and email delivery are separate. A Slack failure does not prevent an independent email notification attempt.
One destination, one form
Each Slack destination belongs to one PostMyForm form, so notifications stay tied to the form that received them.
Credential-safe storage
Saved webhook URLs are treated as credentials, encrypted at rest, and masked after storage.
Destination limits
Slack availability follows your PostMyForm plan.
Trial
No Slack or Discord destinations
Starter
1 destination per form
Growth
Up to 5 total Slack and Discord destinations per form
Growth's limit is shared across Slack and Discord destinations configured for the same form.
Webhook security
Treat every Slack webhook URL as a credential.
PostMyForm masks a saved webhook URL and does not expose the existing value again through the normal customer interface. To change it, provide a complete replacement URL.
Do not place Slack webhook URLs in source code, screenshots, public issue reports, chat messages, or documentation.
Slack delivery questions
Know what the integration does.
Does PostMyForm use a Slack bot or OAuth?
No. PostMyForm sends notifications through Slack incoming webhooks. It is not a Slack bot, OAuth integration, or Slack Marketplace application.
What happens when a Slack destination is disabled?
A disabled destination does not receive live submissions. It remains stored and can still receive an explicit test message.
What happens when Slack delivery fails?
Slack and email delivery are independent. A Slack delivery failure does not prevent a separate email notification attempt.
Do spam-suppressed submissions reach Slack?
No. Spam-suppressed and otherwise blocked submissions do not generate normal Slack integration notifications.
Send your next accepted form submission to Slack.
Create a PostMyForm form, then use the shared Slack and Discord guide to configure an incoming webhook destination.
