Adding Fields

Add event fields with the add action.

New Fields

name: example-add-fields

input:
    echo:
        json: true
        event: |
            {"initialField": "initialValue"}

actions:
- add:
    fields:
        - newField: newValue
        - anotherNewField: newValue

output:
    print: STDOUT

# output:
# {
#     "initialField": "initialValue",
#     "newField": "newValue",
#     "anotherNewField": "newValue"
# }

Overwrite Fields

By default, add won't overwrite existing fields. This behaviour can be changed:

name: example-overwrite-fields

input:
    echo:
        json: true
        event: |
            {"initialField": "initialValue"}

actions:
- add:
    overwrite: true
    fields:
        - initialField: newValue

output:
    print: STDOUT

# output:
# {"initialField": "newValue"}
