Triggers in Xano are workflows that will run only when triggered by another event. You can build triggers for the following events.
Database
New records
Record edits
Record deletes
Table truncate (deleting all records)
Realtime
Channel events
Workspace
New branch
Branch merge
Live branch change
You can find database triggers on each table by clicking the settings icon in the top-right corner.
Click to create a new database trigger.
You can specify what the trigger will execute on. If no data source is set, then it will execute on all data sources.
Select the actions that will activate this trigger.
Inserts Any time a record is added to the table
Updates Any time a record is edited
Deletes Any time a record is deleted
Truncates When the content of the database table is cleared
Finally, you can set up custom filters so that the trigger only runs if the record matches certain conditions. For example, if you only want the trigger to run if a new order is created for a user, or a new user is created with a certain role.
Database triggers have predefined inputs that contain all of the information you'll need to build a workflow based on the database event.
new This is the contents of the new record — if you're adding a record, this will contain the contents of the new record, and if you're updating a record, this will contain the contents of the updated record. On deletes and truncates, this will be empty.
old This is the contents of the old record — if you're deleting or editing a record, this will contain the contents of the record before the change. On inserts and truncates, this will be empty.
action The action that activated the trigger
data source The datasource this trigger has been executed against
Realtime triggers are created per-channel. Once you've created a realtime channel, click the button to create a new channel trigger.
Select the actions that will activate the trigger.
Message Any time a new message is sent to the channel
Join Any time a new connection is made to the channel
Realtime triggers have predefined inputs that contain all of the information you'll need to build a workflow based on the realtime event.
Action and Command This will be either 'join' or 'message' depending on what was responsible for executing the trigger.
Action and Command currently have the same values, but behind the scenes, the values do not come from the same source. We maintain two separate inputs for the purpose of expanding this functionality in the future.
Channel The channel that this command or message is being sent to
commandOptions Any options that are provided with the command being sent to the channel
payload The contents of the command, such as the message body
client An internal client ID
Workspace triggers can be created to execute workflows based on certain workspace-wide events. Currently, these are limited to branch changes.
You can find workspace triggers by clicking the settings icon in the top-right corner of your workspace dashboard.
Click to create a new workspace trigger.
Select the action(s) that will execute this trigger.
Branch Live Any time a branch status is set to live
Branch Merge When a branch is merged
Branch New When a new branch is created
