boolean_smtp_transport_settings_schema

filter Tier B Since 1.0.0

Applies to every transport after the plugin's own fields are in place. Add a field here to collect an extra setting on the connection form — the add-on adds the webhook secret of the providers that report delivery events this way. A field follows the schema shape (`type`, `label`, `required`, `default`, optional `help`, `options`, `visible_when`); its value is stored with the connection and, when its name matches a secret fragment or `boolean_smtp_sensitive_keys`, encrypted.

Signature

Parameters

Parameter	Type	Description
$schema	array<string, array<string, mixed>>	The settings schema, keyed by field name.
