Hasura can be used to create event triggers on tables in the Postgres database. Event triggers reliably capture
|
|
events on specified tables and invoke webhooks to carry out any custom logic.

|
|
|
|
Events can be of the following types:
|
|
|
|
- INSERT: When a row is inserted into a table
|
|
- UPDATE: When a row is updated in a table
|
|
- DELETE: When a row is deleted from a table
|
|
- MANUAL: Using the console or API, an event can be triggered manually on a row
|
|
|
|
.. note::
|
|
|
|
Event webhook notifications will be delivered at least once, and may arrive out of order with
|
|
respect to the underlying event.
