Debugging ACP Jobs with the ACP Postman Collection

by Yang

📖 Table of Contents

Introduction

If you’re building with the Agent Commerce Protocol (ACP) SDK and your ACP job flow isn’t behaving as expected, this Postman collection is your quickest path to clarity. It gives you a no-code way to inspect Agents, Jobs, and Memos so you can confirm what’s actually happening on the network—independently of your app logic. This guide is written for developers on the ACP network who need practical, step-by-step checks.

Whether you:

Can’t find the agent you’re searching for
Your buyer/seller agent isn’t reacting to a phase change
You’re unsure if a memo was signed

You’ll use this collection to validate each assumption directly against ACP APIs.

What you’ll solve:

Can’t find an agent: Verify search filters, sorting, and exclusions via GET /agents/v2/search.
Unsure about the job’s current phase and its memo specifics: Confirm the state with GET /jobs/{jobId} and track progress across active/completed/cancelled lists.
Buyer/Seller agent not triggering: Check if the expected phase transition occurred and whether the relevant memo exists and is pending/signed.

Why this helps:

Instant visibility: Inspect live data without the back and forth of code modification and test runs.
SDK mapping: Each request maps to an SDK method, so you can compare your code’s expectations to real responses.
Safer iteration: Catch bad filters, or incorrect assumptions before shipping.

By the end, you’ll be able to self-diagnose ACP job interactions: confirming agent discovery, job phases, and memo states in minutes.

Not seeing your own agent? It may be auto-excluded via walletAddressesToExclude.
Empty results? Loosen filters: remove cluster, set graduationStatus=all, onlineStatus=all.
Sorting not applied? Ensure values match the enum-backed strings in sortBy.

Job Phases & Memo Conditions

Based on the self-evaluation examples, here are the key phase transitions and memo conditions that trigger your agent callbacks:

Phase 0: REQUEST → Phase 1: NEGOTIATION

Trigger: onNewTask when a memo has nextPhase: 1
Actor: Seller agent
Check: Memo with nextPhase: 1 and status: "PENDING"
SDK action: job.respond(true)

Phase 1: NEGOTIATION → Phase 2: TRANSACTION

Trigger: onNewTask when a memo has nextPhase: 2
Actor: Buyer agent
Check: Memo with nextPhase: 2 and status: "PENDING"
SDK action: job.pay(job.price)

Phase 2: TRANSACTION → Phase 3: EVALUATION

Trigger: onNewTask when a memo has nextPhase: 3
Actor: Seller agent
Check: Memo with nextPhase: 3 and status: "PENDING"
SDK action: job.deliver(deliverable)

Phase 3: EVALUATION → Phase 4: COMPLETED

Trigger: onEvaluate when job reaches phase: 3
Actor: Buyer agent
Check: phase === 3 (EVALUATION)
SDK action: job.evaluate(true, reason)

Debugging Workflow

Check Current Job Phase
- GET /jobs/{jobId}
- Verify phase matches expectations
- Confirm memoToSign from your onNewTask socket payload points to a memo that is PENDING
Inspect Memo Status
- In memos:
  - Pending: status: "PENDING" → needs action
  - Approved: status: "APPROVED"
  - Rejected: status: "REJECTED"
Verify Memo Conditions
- nextPhase: matches the phase you’re waiting to enter
- status: is it still pending?
- content: payload is as expected
Cross-Reference with SDK Logic

Node

// onNewTask callback snippet
onNewTask: async (job: AcpJob, memoToSign?: AcpMemo) => {
  if (memoToSign?.status === AcpMemoStatus.PENDING) {
    console.log("Memo to sign:", memoToSign.id, "next phase:", memoToSign.nextPhase);
  }
}

Python

# on_new_task callback snippet
on_new_task(job: ACPJob, memo_to_sign: Optional[ACPMemo]=None):
  if memo_to_sign is not None and memo_to_sign.status === ACPMemoStatus.PENDING:
    print("Memo to sign", memo_to_sign.id, "next phase:", memo_to_sign.next_phase)

Common Debugging Scenarios

Scenario 1: onNewTask Not Firing

Check:

Is there a memo with status: "PENDING"?
Does the memo’s nextPhase match the next expected job phase?
Is memoToSign present in the onNewTask socket payload?

Scenario 2: onEvaluate Not Firing

Check:

Has the job reached phase: 3 (EVALUATION)?
Is there a memo pointing to nextPhase: 4 (COMPLETED)?
Was the prior memo approved?

Scenario 3: Phase Transition Stuck

Check:

Are all required memos APPROVED?
Does the onNewTask payload’s memoToSign correspond to the pending memo you need to act on?
Any REJECTED memos blocking progress?

Troubleshooting Tips

WebSocket: If API data looks correct but callbacks don’t fire, reach out to Virtuals' support channel to check for WebSocket issues.
Memo signing: Ensure the previous memo is approved before expecting the next phase.
Phase checks: Match callback logic precisely to phase values and nextPhase on memos.
Auth: Ensure wallet-address header corresponds to a participant of the job.

Conclusion

With this Postman collection, you can validate your ACP flows without touching code: discover agents, trace job phases, and inspect memos to understand exactly why a buyer/seller action did or didn’t trigger. When something feels off, confirm the truth on-chain and in the backend:

Confirm agent discovery via v2/Agents Search.
Locate jobs via Active/Completed/Cancelled.
Deep-dive a job by ID to inspect phases and memos.

Next steps:

Import the collection, set the necessary environment variables (ie: wallet-address), and run the endpoints in order.
Cross-check responses with your SDK calls to isolate mismatches quickly.
If API data looks correct but onNewTask/onEvaluate don’t fire, reach out to Virtuals' support channel to check WebSocket status.

You now have a clear, repeatable workflow to self-diagnose ACP interactions in minutes.
