CertifiedTrigger on new FTPS files
File system Trigger
Trigger on new FTPS files
Polls a remote directory on the interval and starts a Flow when new files appear. Sorted with sort (default NONE) before maxFiles truncation. Defaults: port 990, EXPLICIT mode, PROT P data channel, passive mode on, remote IP verification on, paths relative to user home. Use action MOVE/DELETE to prevent repeated triggering; insecureTrustAllCertificates is for testing only.

Properties
action *Requiredstring
MOVEDELETENONEAction to perform on retrieved files
MOVE/DELETE remove the file from the watched directory, so the trigger fires on every listed file. NONE leaves the file in place and relies on stateful deduplication (path + size + last-modified) to avoid reprocessing — handle the file in the Flow accordingly.

List of conditions in order to limit the flow trigger.
Allow events only between two datetimes.
Compares a rendered date (defaults to {{ trigger.date }}) against optional after and before bounds expressed as ISO-8601 datetimes with zone.
You must provide at least one bound; if both are set the date must fall strictly between them. Missing both bounds triggers an evaluation error.

Condition based on the outputs of an upstream execution.
Renders the provided boolean expression against the upstream execution outputs exposed under trigger.outputs.
If the execution exposes no outputs the condition is false and the expression is skipped. A rendered result of blank, space-only, or literal false is treated as false.
The upstream flow_a must explicitly define its outputs
to be used in the ExecutionOutputs condition.

Condition based on variable expression.
Renders a templated expression and treats the result as truthy/falsey to decide whether the condition passes.
Blank strings or the literal false (case-sensitive) evaluate to false; everything else is true. Expressions can reference any flow variables available at evaluation time, so make sure they resolve without errors.
