URL Sequencer Target

URL Sequencer Target properties for Script Engine. Fires up to ten HTTP requests in a timed sequence with per-URL delays and optional repeats. Useful for choreographing pre-show automation (notify control system, start cloud encoders, arm cameras), running scripted health checks against multiple services, kicking off a series of webhooks in a known order, or re-firing a sequence at a fixed cadence throughout a show. Each request reports its status independently and can trigger a Script Engine callback with the response body.

Property	Type	Access	Description
`Url1`	`string`	`get/set`	Full URL for the first request in the sequence. Must include scheme (`http://` or `https://`). Leave any URL slot empty to skip it.
`Url1Delay`	`int`	`get/set`	Delay in milliseconds, measured from sequence start, before request 1 is fired. Set to `0` to fire immediately on Start.
`Url1Status`	`string`	`get`	Live status text for request 1 — sent / succeeded / failed / timed out, including HTTP status code and response time when available (read-only, debug).
`Url2`	`string`	`get/set`	Second URL in the sequence. Leave empty to skip.
`Url2Delay`	`int`	`get/set`	Delay in milliseconds, measured from sequence start, before request 2 is fired.
`Url2Status`	`string`	`get`	Live status text for request 2 (read-only, debug).
`Url3`	`string`	`get/set`	Third URL in the sequence. Leave empty to skip.
`Url3Delay`	`int`	`get/set`	Delay in milliseconds, measured from sequence start, before request 3 is fired.
`Url3Status`	`string`	`get`	Live status text for request 3 (read-only, debug).
`Url4`	`string`	`get/set`	Fourth URL in the sequence. Leave empty to skip.
`Url4Delay`	`int`	`get/set`	Delay in milliseconds, measured from sequence start, before request 4 is fired.
`Url4Status`	`string`	`get`	Live status text for request 4 (read-only, debug).
`Url5`	`string`	`get/set`	Fifth URL in the sequence. Leave empty to skip.
`Url5Delay`	`int`	`get/set`	Delay in milliseconds, measured from sequence start, before request 5 is fired.
`Url5Status`	`string`	`get`	Live status text for request 5 (read-only, debug).
`Url6`	`string`	`get/set`	Sixth URL in the sequence. Leave empty to skip.
`Url6Delay`	`int`	`get/set`	Delay in milliseconds, measured from sequence start, before request 6 is fired.
`Url6Status`	`string`	`get`	Live status text for request 6 (read-only, debug).
`Url7`	`string`	`get/set`	Seventh URL in the sequence. Leave empty to skip.
`Url7Delay`	`int`	`get/set`	Delay in milliseconds, measured from sequence start, before request 7 is fired.
`Url7Status`	`string`	`get`	Live status text for request 7 (read-only, debug).
`Url8`	`string`	`get/set`	Eighth URL in the sequence. Leave empty to skip.
`Url8Delay`	`int`	`get/set`	Delay in milliseconds, measured from sequence start, before request 8 is fired.
`Url8Status`	`string`	`get`	Live status text for request 8 (read-only, debug).
`Url9`	`string`	`get/set`	Ninth URL in the sequence. Leave empty to skip.
`Url9Delay`	`int`	`get/set`	Delay in milliseconds, measured from sequence start, before request 9 is fired.
`Url9Status`	`string`	`get`	Live status text for request 9 (read-only, debug).
`Url10`	`string`	`get/set`	Tenth URL in the sequence. Leave empty to skip.
`Url10Delay`	`int`	`get/set`	Delay in milliseconds, measured from sequence start, before request 10 is fired.
`Url10Status`	`string`	`get`	Live status text for request 10 (read-only, debug).
`RepeatSequence`	`bool`	`get/set`	When enabled, the sequence restarts after the last URL fires, separated by `RepeatDelay` and bounded by `MaxRepeats`. Useful for fixed-cadence health checks or periodic notifications throughout a long-running show.
`RepeatDelay`	`int`	`get/set`	Pause in milliseconds added after the last URL in the sequence fires before the sequence restarts. Only used when `RepeatSequence` is on.
`MaxRepeats`	`int`	`get/set`	Maximum number of times the sequence repeats after the initial run. Set to `0` to repeat indefinitely until the user presses Stop. Only used when `RepeatSequence` is on.
`RepeatCounter`	`int`	`get`	How many times the sequence has repeated so far (read-only, debug).
`UrlSequencerStatus`	`TargetState`	`get`	Overall state of the sequencer (idle, running, finalizing, completed) (read-only, debug).
`TotalRequestsSent`	`int`	`get`	Cumulative count of HTTP requests sent across all repeats (read-only, debug).
`TotalRequestsFailed`	`int`	`get`	Cumulative count of failed requests across all repeats — non-2xx responses, timeouts and network errors (read-only, debug).
`LoggingMode`	`LoggingMode`	`get/set`	How issues like invalid URLs or network failures appear in the log — as warnings or as errors. Use `Warning` for non-critical sequences, `Error` when failed requests should be visible during operations.
`StartCommand`	`Command`	`get`	Begins the sequence from the top. Validates URLs first; if any are invalid the sequence does not run and a warning is shown via `UrlValidationNote`.
`StopCommand`	`Command`	`get`	Stops the sequence. In-flight requests are cancelled and any pending repeats are skipped.
`ResetCommand`	`Command`	`get`	Clears all ten URLs, their delays, status fields and the repeat counters. Use to start over from a blank configuration. Has no effect while the sequence is running.
`RequestResponseCallback`	`string`	`get/set`	Name of a Script Engine function called once per request as soon as the response arrives. The script receives a JSON object with the URL id, status code, response body, request timestamp and response time. Leave empty to skip.
