Incoming webhooks

This feature lets external platforms send webhook events directly to Loops, making it straightforward to create or update contacts in Loops automatically when changes happen in other platforms. You can also trigger events when webhooks arrive in Loops so you can send automated email after something happens in your other accounts.

​

How it works

First, you create webhook endpoints in your Loops account. These allow other platforms to send data automatically and directly to Loops. You then create webhooks in the external platforms, which send event data to your Loops endpoint URLs. Note: we only process webhook events listed below for each provider (and which contain an email address). We return helpful messages in responses if there is an issue processing a webhook event. Check the webhook logs in your external platforms.

​

Syncing contacts

The primary use case for incoming webhooks is to create and update contacts in your Loops audience. When data arrives in Loops, we grab the email address to create and update contacts in your Loops audience. To this end, we only support incoming events that contain an email address. You can assign a user group value to each new contact, which allows you to create segments from webhook-created contacts. Any new contact created via a webhook will have a source like “Stripe webhook” so you know where it originated from. For events that reference record deletion, like Stripe’s customer.deleted event, you can choose to unsubscribe or delete contacts in Loops.

Subscribing to mailing lists

You can subscribe contacts to mailing lists when they are created or updated via a webhook.

​

Sending emails

Incoming webhooks can also trigger loops if you specify an event in the Trigger an event section. This can be useful to automatically send emails when something has happened in the external platform, for example a successful payment in Stripe or a new sign up in Clerk.

​

Create webhook endpoints in Loops

To start sending webhook events to Loops, go to your chosen integration’s settings page in Loops. A webhook endpoint will be created for you. Copy the endpoint URL and paste it into your external platform. You may need to copy-paste signing secrets between the platform and Loops for extra security (we will prompt you when this is necessary and give you the steps to do it). In the endpoint form, you can select the events you want Loops to process, assign a user group, and send a Loops event (which can trigger email sending in loops).
