  title: Loops Webhooks
  version: 1.21.6
  description: Event catalog for the Loops webhook surface, derived operation-for-operation from the `webhooks` block of the Loops OpenAPI 3.1 document (info.version 1.21.6, published at https://app.loops.so/openapi.json). Loops does not publish an AsyncAPI document; it publishes these events inside its OpenAPI, and this file is a faithful projection of that block into AsyncAPI 3.0.0 so the event surface is readable by event tooling. Every channel, message name, summary and payload schema below comes verbatim from the provider. Delivery is a single HTTP POST to one subscriber-configured endpoint per Loops account, signed with HMAC-SHA256 over `{webhook-id}.{webhook-timestamp}.{raw-body}` and capped at 10 events per second.

    contactUnsubscribed:
      name: contactUnsubscribed
      title: Contact unsubscribed
      summary: Sent when a contact is unsubscribed from your audience, or when a contact is deleted from your audience (alongside `contact.deleted`). This is not the same as a contact unsubscribing from a mailing list (see `contact.mailingList.unsubscribed`). Contains a `contactIdentity` object.
      contentType: application/json
      payload:
        $ref: '#/components/schemas/WebhookContactUnsubscribedPayload'

    contactCreated:
      name: contactCreated
      title: Contact created
      summary: Sent when a new contact is created in your audience. Contains a `contactIdentity` object and a full `contact` object with all of the new contact's properties (including custom properties). When double opt-in is enabled, contact webhooks do not fire until the contact is confirmed; `contact.created` only fires for form-created contacts once they confirm their subscription. `optInStatus` will never be `"pending"` or `"rejected"` for this event.

      title: Contact subscribed to mailing list
      summary: Sent when a contact is subscribed to a mailing list. Contains `contactIdentity` and `mailingList` objects. When double opt-in is enabled, this event only fires after the contact confirms their subscription.

      payload:
        $ref: '#/components/schemas/WebhookTransactionalEmailSentPayload'
      headers:

    campaignEmailSent:
      name: campaignEmailSent
      title: Campaign email sent
      summary: Sent when a campaign email is sent to a contact. This event fires for every campaign send (for example, sending to 1,000 contacts produces 1,000 events). Contains `campaignId` and `campaignName` plus `contactIdentity` and `email` objects. If the campaign was sent to one or more mailing lists, a `mailingLists` array is also included.

    loopEmailSent:
      name: loopEmailSent
      title: Loop email sent
      summary: Sent when a workflow email is sent to a contact. This event keeps its `loop` naming for compatibility (Loops was renamed to Workflows on May 6, 2026). This event fires for every contact in a workflow (for example, 1,000 recipients produces 1,000 events). Contains `loopId` and `loopName` plus `contactIdentity` and `email` objects. If the workflow was sent to one or more mailing lists, a `mailingLists` array is also included.

    emailSoftBounced:
      name: emailSoftBounced
      title: Email soft bounced
      summary: Sent when an email soft bounces. Soft bounces are temporary delivery failures (for example, a connection timing out). Soft bounces are retried multiple times and the email may still be delivered. Contains `sourceType` and the related `campaignId`, `loopId` (workflow ID), or `transactionalId`, plus `contactIdentity` and `email` objects.
      contentType: application/json
      payload:
        $ref: '#/components/schemas/WebhookEmailSoftBouncedPayload'

    emailHardBounced:
      name: emailHardBounced
      title: Email hard bounced
      summary: Sent when an email hard bounces. Hard bounces are persistent delivery failures (for example, a mailbox that does not exist); the email will not be delivered. In Loops, a hard bounce also unsubscribes the contact from your audience, so a `contact.unsubscribed` event will also be sent. Contains `sourceType` and the related `campaignId`, `loopId` (workflow ID), or `transactionalId`, plus `contactIdentity` and `email` objects.
      contentType: application/json

    emailClicked:
      name: emailClicked
      title: Email clicked
      summary: Sent when a link in a campaign or workflow email is clicked. Not available for transactional emails because link clicks are not tracked for transactional emails. Contains `sourceType` and the related `campaignId` or `loopId` (workflow ID), plus `contactIdentity` and `email` objects.
      contentType: application/json
      payload:
        $ref: '#/components/schemas/WebhookEmailClickedPayload'
      headers:
        $ref: '#/components/schemas/LoopsWebhookHeaders'
    emailUnsubscribed:
      name: emailUnsubscribed
      title: Email unsubscribed
      summary: Sent when a recipient unsubscribes from marketing email or a mailing list using an email's "Unsubscribe" link. A `contact.unsubscribed` or `contact.mailingList.unsubscribed` event will also be sent depending on whether the email was sent to a mailing list. Not available for transactional emails because unsubscribe links are not included for transactional emails. Contains `sourceType` and the related `campaignId` or `loopId` (workflow ID), plus `contactIdentity` and `email` objects.
      contentType: application/json
      payload:
        $ref: '#/components/schemas/WebhookEmailUnsubscribedPayload'

    emailResubscribed:
      name: emailResubscribed
      title: Email resubscribed
      summary: Sent when a recipient resubscribes to marketing email from an email's preference center ("Unsubscribe" link). Not available for transactional emails because unsubscribe links are not included for transactional emails. Contains `sourceType` and the related `campaignId` or `loopId` (workflow ID), plus `contactIdentity` and `email` objects.
      contentType: application/json

    emailOpened:
      name: emailOpened
      title: Email opened
