Set Prefill Storage Node

The Set Prefill Storage node saves custom property values to storage and returns a storage ID that can be used later to retrieve the data. This enables users to prefill information in subsequent flows without reentering the same data.

warning

Node is used exclusively for TellUs.

Use Case

Use the Set Prefill Storage node when:

• You need to save custom property values during a flow for later retrieval.
• You want to prefill information in subsequent flows so users don't have to reenter the same data.

Don't use the Set Prefill Storage node when:

• You do not need to save any custom property values for later use.

UI Examples

Behavior

• Blocking: the node waits for property values to be saved to storage before proceeding
• Produces output: returns a storage ID that uniquely identifies the saved data, along with a status result (Ok or error)
• Supports validation: can be marked as required/optional; validates that properties are configured for storage
• Moves to the next node after the storage operation completes successfully
