Issuer Processor Action Queue Help and Documentation

Learn how to prioritize issuer work, search the queue, interpret task and resolution states, open investigations, review timelines and replays, and move queue items toward resolution.

Action Queue Overview

The Issuer Processor Action Queue is a prioritized operator worklist generated from issuer-health alert signals.

Use it to:

  • Identify critical and warning-level issuer tasks.
  • Review recommended actions and routing reasons.
  • Open the correct issuer investigation context.
  • Review historical timeline and replay evidence.
  • Track assignment, task status, and resolution state.

Status Banner and Live Refresh

The queue-pressure banner summarizes the most serious current workload.

Critical queue pressure A red banner means at least one critical queue item exists. Review critical items before lower-severity work unless an approved operating procedure says otherwise.

Action Queue Active

The pulsing green indicator confirms that the page's active refresh behavior is running. The “Last refreshed” text shows how recently the visible content was refreshed.

Green heartbeat does not mean healthy issuers It indicates that the page is active, not that the queue is clear.

Summary Cards

Queue Workflow Strip

The page presents the intended operational sequence:

  1. Review: Read the signal, severity, priority, and recommendation.
  2. Investigate: Open the issuer investigation context.
  3. Timeline: Review event sequence and historical behavior.
  4. Replay: Reconstruct how Zahlen interpreted the evidence.
  5. Resolve: Complete the approved operational action and update status.

Clickable Queue Rows

Each queue row is itself clickable. Selecting a row outside one of its action links opens the issuer investigation page.

Keyboard users can focus the row and press Enter or the Space bar to open the investigation.

Action links take priority Selecting Investigate Now, Investigation, Timeline, or Replay opens that specific destination instead of triggering the general row link.

Action Buttons

Investigate Now

Investigate Now is the primary action. It opens the issuer investigation page with BIN, country, card brand, and observation window already populated.

Use it when you are ready to begin immediate review of the selected queue item.

Investigation

Investigation opens the same issuer investigation context as a secondary navigation option.

Timeline

Timeline opens the historical issuer-health timeline for the row's issuer and observation window.

Use it to determine whether the signal is isolated, recurring, improving, or worsening.

Replay

Replay opens the evidence replay for the selected issuer and time window.

Use it to reconstruct the system's interpretation before deciding how to resolve the task.

Task and Resolution States

open

Work exists and has not yet been completed.

active

Work is acknowledged or in progress.

resolved

The work or underlying condition has been completed or resolved.

Unassigned

No operator is currently recorded as responsible for the item.

Dash in Last Action At

No prior task action timestamp is recorded.

Priority, Confidence, and Routing

Severity and priority indicate urgency, but operators should also read the summary, confidence, telemetry context, and routing reason.

Initial-decline data can show zero recovery A task showing 0 recovered events may come from an initial decline file before retry outcomes are available. Low confidence and no truth-linked telemetry should influence how urgently and conclusively the signal is interpreted.
Do not resolve from the table summary alone Review Investigation, Timeline, and Replay evidence before making a processor or customer-impacting decision.

Recommended Action Queue Workflow

  1. Read the queue-pressure banner.
  2. Review Critical items before Warning and Info items.
  3. Search by BIN, severity, metric, or queue when narrowing the worklist.
  4. Read Summary, Recommended Action, and Routing Reason.
  5. Open Investigate Now for the highest-priority task.
  6. Use Timeline to understand sequence and duration.
  7. Use Replay to validate the system's interpretation.
  8. Confirm assignment and ownership.
  9. Perform the approved operational action.
  10. Update task and resolution status through the applicable workflow.
