Variables
A reference guide for the variables available in the template editor.
When you build workflows in Knock, we auto-generate certain pieces of state (as a result of batch functions and other workflow steps) that you can use to control the copy you display to your end users in your notification templates.
| Variable | Description |
|---|---|
activities | A list of the activity objects included within the batch, where each activity equals the state sent across in your trigger call, and also includes the actor who performed the message and a timestamp of when the activity occurred. |
actor | A serialized Recipient of the actor that triggered the workflow (may be null). Will include any custom properties set. |
actors | A list of up to 10 of the unique actors included within the batch. |
current_message | A serialized CurrentMessage (see below). |
data | The complete data passed to the workflow trigger. |
recipient | A serialized Recipient of the recipient of the workflow. Will include any custom properties set. |
tenant | A serialized Tenant (see below) which is set when a tenant is passed to the workflow trigger. |
timestamp | The time in which the activity occurred, as an ISO-8601 datetime string. |
