When to use it

  • People need to request, register or report something, with or without an account.
  • You want validated input without building a web page.
  • Only invited people, or holders of an expiring link, should be able to submit.

Reach for something else when

Wait for formWhen a flow that is already running needs a person to review or approve.WebhookWhen the data comes from another system.

Example

A new-hire request form starts a flow that creates the user account and tells the IT team in Slack.

  2. Map fields
  3. Microsoft Entra ID
  4. Slack

How it works

Pick the Form (a draft form shows a warning; publish it for the trigger to work), check the Output sample, and choose Who can submit: Anyone with the link, Capability link only (signed, expiring links), or Named people only (a list of emails). Inbound access rules apply as for webhooks. See Forms.
