Remove Null Properties - Docs

This transformation removes null properties from the event properties object. If the object nesting exceeds 3 levels, deeper levels will be returned unchanged.

Using our REST API you can create this transformation like so:

Terminal

# Create a new destination
curl --location 'https://us.i.posthog.com/api/environments/:project_id/hog_functions' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer <POSTHOG_PERSONAL_API_KEY>' \
--data '{
    "type": "transformation",
    "name": "Remove Null Properties",
    "inputs": {},
    "enabled": true,
    "template_id": "template-remove-null-properties"
}'
