Setting up your first event trigger¶

Introduction¶

You can use Hasura to setup event triggers that call configured webhooks whenever specific database events occur.

Let’s create a sample event trigger with https://httpbin.org as our simple webhook.

Create a table¶

Head to the Hasura console, navigate to Data -> Add table and create a sample table called profile with the following columns:

profile (
  id INT PRIMARY KEY,
  name TEXT
)

Set up an event trigger¶

In the Hasura console, navigate to Events -> Create and:

1. Enter trigger name as echo.
2. Select table profile from the table dropdown.
3. Select operations: insert, update and delete.
4. Enter webhook URL as: https://httpbin.org/post.
5. Then click on the Create Event Trigger button.

This sets up our webhook https://httpbin.org/post to receive database changes on an insert, update and delete on the profile table.

Watch the trigger in action¶

1. Insert some sample data into the profile table using the Insert Row tab.
2. Now navigate to the Events tab and click on the echo trigger in the left sidebar.
3. Click on the Processed Events tab to see the response(s) from the webhook.
