Replay QA API

Use the Replay QA REST API directly when a task needs Replay QA analysis. This skill is instructions-only: do not use Replay MCP tools, Codex apps, or plugin hooks as substitutes for Replay QA REST API calls.

Replay.io Skill Prerequisite

Before making any Replay QA API call, make sure the replayio skill in this same Codex plugin bundle has been loaded and applied for the current session.

If setup is unknown, load ../replayio/SKILL.md first and follow it before continuing. In particular, verify:

• REPLAY_API_KEY is mapped from SECRET_REPLAY_API_KEY when available.
• REPLAY_QA_API_KEY is mapped from SECRET_REPLAY_QA_API_KEY.
• AGENT_BROWSER_EXECUTABLE_PATH points at Replay Chromium.
• RECORD_ALL_CONTENT and RECORD_REPLAY_VERBOSE are set.
• Any Replay recording referenced by Replay QA has uploaded or has a concrete recording UUID.

Do not proceed with project creation or polling if this prerequisite is unknown. Load and apply the replayio skill first, then return to this skill.

Authentication

Replay QA API tokens are bearer tokens that start with lqa_. Generate one in Replay QA Settings and store it as SECRET_REPLAY_QA_API_KEY when the host supports project secrets. Map it before calling the API:

if [ -z "${REPLAY_QA_API_KEY:-}" ] && [ -n "${SECRET_REPLAY_QA_API_KEY:-}" ]; then
  export REPLAY_QA_API_KEY="$SECRET_REPLAY_QA_API_KEY"
fi

test -n "${REPLAY_QA_API_KEY:-}"

Never print the token.

Base URL

Use:

export REPLAY_QA_API_BASE="${REPLAY_QA_API_BASE:-https://qa.replay.io/api/v1}"

All requests need:

-H "Authorization: Bearer $REPLAY_QA_API_KEY"
-H "Content-Type: application/json"

Create A Project From A Replay Recording

Use this when you already have an uploaded Replay recording UUID. When recording_id is present, target_url is not required.

Required input:

• name: clear project or scenario name.
• recording_id: Replay recording UUID.
• instructions: include the raw test source URL when possible and the exact failure message or stack.
• webhook_url: optional.

curl -sS -X POST "$REPLAY_QA_API_BASE/projects" \
  -H "Authorization: Bearer $REPLAY_QA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "S01 - checkout total does not update",
    "recording_id": "00000000-0000-0000-0000-000000000000",
    "instructions": "Analyze this Replay recording of a failing automated test.\n\nTest source:\nhttps://raw.githubusercontent.com/org/repo/refs/heads/branch/tests/checkout.spec.ts\n\nError:\nExpected checkout total to update after clicking Confirm Checkout.\n\nExplain the root cause and the code change that should fix it."
  }'

Save the returned project id and project url if present. If only an id is returned, the overview URL is:

https://qa.replay.io/p/:projectId/overview

Create A Project For Live App Exploration

Use this when Replay QA should explore an app URL instead of analyzing one recording.

curl -sS -X POST "$REPLAY_QA_API_BASE/projects" \
  -H "Authorization: Bearer $REPLAY_QA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Todo app smoke exploration",
    "target_url": "https://example.com",
    "instructions": "Explore the main user flows and report correctness, polish, and UX bugs."
  }'

Optional fields supported by the API include webhook_url, backend_recording_url, backend_log_url, logins, and design_document. Only include credentials when the user explicitly provided them for this app.

Poll Project Status

Poll every 30 seconds until the project reports completion. Status can be returned either at the top level or under project.status, so inspect the response shape instead of assuming one field.

PROJECT_ID="..."

curl -sS "$REPLAY_QA_API_BASE/projects/$PROJECT_ID/status" \
  -H "Authorization: Bearer $REPLAY_QA_API_KEY"

For long-running analysis, report that Replay QA is still processing rather than guessing from partial data.

Fetch Bugs

List bugs:

curl -sS "$REPLAY_QA_API_BASE/projects/$PROJECT_ID/bugs?page_size=100" \
  -H "Authorization: Bearer $REPLAY_QA_API_KEY"

Filter open bugs:

curl -sS "$REPLAY_QA_API_BASE/projects/$PROJECT_ID/bugs?status=open&page_size=100" \
  -H "Authorization: Bearer $REPLAY_QA_API_KEY"

Fetch full bug detail:

BUG_ID="..."

curl -sS "$REPLAY_QA_API_BASE/bugs/$BUG_ID" \
  -H "Authorization: Bearer $REPLAY_QA_API_KEY"

Use bug detail as the source of truth for root cause, reproduction steps, expected behavior, actual behavior, severity, and Replay evidence.

Journeys, Test Runs, And Explorations

List journeys:

curl -sS "$REPLAY_QA_API_BASE/projects/$PROJECT_ID/journeys?page_size=100" \
  -H "Authorization: Bearer $REPLAY_QA_API_KEY"

List test runs:

curl -sS "$REPLAY_QA_API_BASE/projects/$PROJECT_ID/test-runs?page_size=100" \
  -H "Authorization: Bearer $REPLAY_QA_API_KEY"

List explorations:

curl -sS "$REPLAY_QA_API_BASE/projects/$PROJECT_ID/explorations?page_size=100" \
  -H "Authorization: Bearer $REPLAY_QA_API_KEY"

Start another exploration:

curl -sS -X POST "$REPLAY_QA_API_BASE/projects/$PROJECT_ID/explorations" \
  -H "Authorization: Bearer $REPLAY_QA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "Re-test checkout, saved drafts, and navigation edge cases.",
    "agent_count": 3
  }'

agent_count must be between 1 and 10.

Fix Workflow Discipline

When Replay QA is used to guide fixes:

1. Create Replay QA projects for all selected failing recordings before fixing.
2. Wait for each selected project to finish analysis.
3. Fetch full bug details.
4. Group bugs by root cause and affected file.
5. Patch only from Replay QA evidence plus the current source file.
6. Re-run the app or tests with Replay agent-browser recording enabled.
7. Report project IDs, bug IDs, recording IDs, files changed, and remaining undiagnosed failures.

Do not infer a root cause from source reading while Replay QA analysis is still pending.

Reporting

When reporting Replay QA API work, include:

• Project ID and URL, if returned.
• Recording ID or target URL analyzed.
• Status response summary.
• Bug count and each bug ID inspected.
• Root cause and recommended fix from bug detail.
• Any 401, 404, rate limit, or incomplete-analysis blocker.
