Request Settings

The Settings tab on a request lets you fine-tune how PruTAN sends that request. The available options depend on the request type — REST requests and ISO requests expose different settings.

The Settings tab is available for logged-in users, since these options are saved with the request.

ISO Request Settings

For an ISO request, the Settings tab lets you control how the ISO 8583 message is framed and which spec it uses.

Message Representation

How the ISO message payload is represented on the wire:

Value	Description
`bytes`	Raw byte stream (default)
`array`	Array representation

Spec

Selects the ISO specification that defines the message structure. The dropdown lists the specs available in your workspace. See Spec for creating specs.

Links a saved test card to this request, so the request can use the card's values, such as {{card.pan}}. Pick From environment if you want the selected environment to choose the card. See Card Engine.

Header Size

The ISO message header length used when framing the message:

Value	Description
`2`	2-byte length header
`4`	4-byte length header (default)
`4_VISA`	4-byte VISA-style length header

Request Timeout

The maximum time (in milliseconds) PruTAN waits for a response before the request times out. Default is 5000 ms.

Send when idle for (s)

This turns the request into the automatic echo for its host. When the connection is kept open and nothing has been sent to that host for N seconds, PruTAN sends this request by itself. This way the switch keeps the connection open. Blank means off.

It only works when the workspace keeps connections open (Settings → Connection Configuration). N must be shorter than that setting, or PruTAN refuses to save. Which request to pick, what you see, and how to stop it are all explained on Persistent Connections.

The old per-request Persist Connection toggle is gone. Whether a connection is kept open is now one setting for the whole workspace.
