If you are looking to send Supabase authentication emails with Loops, check out our Supabase SMTP docs.

Our Supabase integration lets you:

  • Create and update contacts
  • Send events to trigger loops

Our Supabase integration is built on top of our Incoming webhooks feature. This system lets you send webhooks from supported platforms directly to Loops so you can easily sync users and customers as well as send automated emails.

Please read our guide about incoming webhooks

With Supabase, you can keep your user data synced to Loops so you can send emails to your userbase.

​
Supported events

We accept the following database events for the “Users” table:

  • INSERT
  • UPDATE
  • DELETE

Supabase database webhooks docs

Events from other tables will be ignored.

​
Synced data

For INSERT and UPDATE events, we sync the following Supabase data to your Loops contacts:

  • User ID
  • Email address

We use the IDs of Supabase users to match contacts in your Loops audience. If the user ID is not found in Loops, we will create a new contact.

DELETE events can be used to delete or unsubscribe your Supabase users from your Loops audience.

​
Create a webhook endpoint in Loops

Follow the instructions here to create a new webhook endpoint, which will allow you to send webhook events directly to Loops.

​
Create a database hook in Supabase

Next, you need to set up database hooks in Supabase.

Inside a project in Supabase, go to Integrations -> Database Webhooks -> Webhooks and click Create a new hook.

Give a name to your webhook, select “auth users” from the Table dropdown, and select the event(s) you want to get webhooks for.

Make sure HTTP Request is selected in the Webhook configuration section. In the HTTP Request section, paste in the endpoint URL from Loops into the URL field.

The last step is to secure requests with a header. In the HTTP Headers section, click + Add a new header. From the Secret header section in Loops, paste in the Header name (“Loops-Secret”) and Header value values into the form.

Click Create webhook to finish.

​
Testing Supabase webhooks

You can test a user webhooks by creating, editing and deleting users from the Authentication -> Users page in Supabase, or by signing up in your application.

On Loops’ end, you will see new contacts appear in your Audience page, and triggered events in the Events page.
