feat(connectors): Connector Framework + Zalo OA connector#17
Merged
Conversation
Kicks off the Month-1 roadmap (magic-business technical-planning): a BaseConnector interface, ConnectorRegistry, AuthHandler abstractions (API key / OAuth2 / webhook signature), retryable error hierarchy, and Common Data Schema (Customer, Order, Case, Conversation, Message, KnowledgeDocument) in sdk/python/magic_ai_sdk/connectors — plus a first connector implementation (Zalo OA: send message, webhook receive with verified signature) under connectors/zalo, built as an external worker per the existing "core never contains platform-specific logic" principle. Also adds a 1-click docker-compose.yml (magic + postgres + redis) and scripts/quickstart.sh for local dev.

Code Review
This pull request introduces the MagiC Connector Framework and a basic Zalo Official Account connector, supporting message exchange, webhook handling, and tenant-isolated registration. The review feedback highlights several critical improvements: implementing an asyncio.Lock to serialize token refreshes and prevent concurrent invalidation of single-use refresh tokens, handling specific token expiration errors as transient to trigger retries, properly parsing Unix timestamps to avoid Pydantic validation errors, securing webhook signature verification against timing attacks using hmac.compare_digest with safe UTF-8 decoding, handling potential parsing errors on Content-Length in the webhook server, and enforcing type safety in the message schema with a direction Enum.
Important
The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
For more details on the timeline and next steps, please review the Help Documentation.

Since Zalo's refresh tokens are single-use, concurrent requests calling _ensure_token when the token is expired will trigger multiple concurrent refresh requests. The first one will succeed and invalidate the refresh token, causing the second one to fail and permanently lock out the connector. We should use an asyncio.Lock to serialize token refresh attempts.

If Zalo returns an invalid or expired token error (e.g., error codes -203 or -216), the current implementation raises a PermanentError, which is not retried. We should clear the cached expiry and raise a TransientError so that the request is retried with a fresh token.

Zalo's timestamp is a Unix timestamp (usually in milliseconds as a string or integer). Passing a raw string of digits directly to Pydantic's datetime field (sent_at) can cause validation errors in Pydantic v2. We should parse the timestamp to a timezone-aware UTC datetime object before returning.
timestamp_raw = raw_data.get("timestamp")
sent_at = None

ts = float(timestamp_raw)

There was a problem hiding this comment.
The signature verification is vulnerable to timing attacks due to standard string comparison (==). Additionally, calling raw_body.decode() outside the try-except block can raise an uncaught UnicodeDecodeError if the payload contains invalid UTF-8 bytes. We should decode safely inside the try-except block and use hmac.compare_digest for timing-attack-safe comparison.

If the Content-Length header is present but not a valid integer, calling int(content_length) will raise a ValueError, crashing the request handler with an unhandled exception. We should wrap it in a try-except block and return a clean 400 Bad Request.

The direction field in the Message model is defined as a plain str. To prevent typos and enforce type safety, we should define a MessageDirection enum (with inbound and outbound values) and use it as the type for direction.

- Remove unused import (fixes Python Tests CI lint failure) - Serialize Zalo access-token refresh with asyncio.Lock — refresh tokens are single-use, so concurrent refreshes could lock out the connector (Gemini review, critical) - Treat Zalo token-expired error codes (-203/-216) as TransientError that forces a refresh + retry, instead of failing permanently - Use hmac.compare_digest for webhook signature comparison instead of `==` (timing-attack safe — this is what SonarCloud's "B Security Rating on New Code" gate was flagging) and decode the body safely inside the try/except so invalid UTF-8 can't crash the handler - Guard webhook Content-Length parsing against non-numeric values (400 instead of an unhandled ValueError crashing the request thread) - Add MessageDirection enum instead of a free-form str field Verified pydantic v2 already parses numeric epoch-second/millisecond strings into datetime correctly, so the "timestamp parsing" review comment needed no code change. New/updated tests: token-expiry-triggers-retry, concurrent-refresh-is- serialized, and a new test_webhook.py exercising the real HTTP server (valid signature, invalid signature, malformed Content-Length).

Root cause of the lingering "C Reliability Rating on New Code" gate on PR #18, which persisted even after the Google Sheet connector's own redundant excepts were fixed in 89d2db5. UnicodeDecodeError and json.JSONDecodeError are both subclasses of ValueError, so listing them alongside ValueError in the same except tuple is dead weight — SonarCloud rule python:S5713, which it classifies as a Bug (Reliability), not a code smell. It's the same rule SonarCloud flagged on PR #17 (connector.py:163) before that PR merged. Because the Zalo connector landed on main today (PR #17), it still falls inside SonarCloud's New Code window, so its issues counted against PR #18's quality gate even though PR #18 doesn't touch those files. Behavior is unchanged: the same exceptions are still caught, just via their common base class. Left sdk/python/magic_ai_sdk/worker.py:131 (same pattern) untouched on purpose — it's long-standing code outside this PR's scope, and editing it would pull the whole file into Sonar's new-code window. Tests: zalo 22, google_sheet 22, sdk/python 36 — all passing.

* feat(connectors): add Google Sheet connector (Week 2 roadmap)
Second connector per MAGIC_MONTH1_TASK_LIST.md (magic-business): reads
and writes Order/Customer data in a Google Sheet, for shops without a
dedicated order-management system yet.
- Auth via Google service account (JWT bearer through google-auth);
the actual Sheets API v4 calls go through httpx like the Zalo
connector, so credential refresh uses a small httpx-based adapter
for google.auth.transport.Request instead of pulling in the separate
`requests` library just for that one call.
- Operations: read_range, update_range, append_row, batch_update
- Common Schema mapping is header-name-based (Customer/Order), with
Order.items round-tripped as a JSON string in an items_json column
since sheets have no nested types
- Error mapping follows Google's standard {error: {code, status,
message}} shape: RESOURCE_EXHAUSTED -> RateLimitError, 5xx/UNAVAILABLE/
INTERNAL -> TransientError (retried), everything else -> PermanentError
- 13 tests (auth mocked, no real RSA key needed; HTTP mocked via respx)
connectors/README.md updated to reflect google_sheet is implemented.
* fix(connectors): address review feedback on Google Sheet connector
Fixes the SonarCloud "C Reliability Rating" gate failure and Gemini/
CodeRabbit review comments on PR #18:
- Replace `assert self._client is not None` with an explicit check +
PermanentError — assertions are stripped under `python -O`, so this
was flagged as a real reliability bug, not just style
- connect(): close and clear the httpx client if token init fails
during connect(), instead of leaking it
- _request(): catch GoogleAuthError (covers RefreshError and friends)
and raise AuthError — a revoked/invalid service account key isn't
fixed by retrying, so it shouldn't go through with_retry; genuine
network errors during token refresh still flow through the existing
httpx.RequestError -> TransientError path since token fetch now runs
inside the same try block as the request
- _request(): treat HTTP 401 as TransientError and clear the cached
token so the retry is forced to refresh, instead of failing
permanently on a token that expired mid-flight
- map_to_common_schema: reject non-dict raw_data, only accept a JSON
list (not object/other) for items_json, and parse total_amount/
shipping_fee defensively instead of letting a malformed cell crash
the whole mapping
- map_from_common_schema: accept Pydantic models (via model_dump/dict)
in addition to plain dicts, default items to [] instead of "null"
- Simplify redundant `except (json.JSONDecodeError, ValueError)` to
just ValueError (JSONDecodeError is already a ValueError subclass);
use resp.is_success instead of `== 200`
- README: warn that config.yaml/service-account key are secrets and
shouldn't be committed, use repo-root-relative paths consistently,
and document that map_from_common_schema writes in a fixed column
order (reordering sheet columns will misalign writes)
9 new/updated tests covering the above; all passing (22 total in this
connector, 36 in sdk/python, 22 in zalo — none affected).
* fix(connectors): remove redundant exception classes in Zalo connector
Root cause of the lingering "C Reliability Rating on New Code" gate on
PR #18, which persisted even after the Google Sheet connector's own
redundant excepts were fixed in 89d2db5.
UnicodeDecodeError and json.JSONDecodeError are both subclasses of
ValueError, so listing them alongside ValueError in the same except
tuple is dead weight — SonarCloud rule python:S5713, which it classifies
as a Bug (Reliability), not a code smell. It's the same rule SonarCloud
flagged on PR #17 (connector.py:163) before that PR merged.
Because the Zalo connector landed on main today (PR #17), it still falls
inside SonarCloud's New Code window, so its issues counted against
PR #18's quality gate even though PR #18 doesn't touch those files.
Behavior is unchanged: the same exceptions are still caught, just via
their common base class.
Left sdk/python/magic_ai_sdk/worker.py:131 (same pattern) untouched on
purpose — it's long-standing code outside this PR's scope, and editing
it would pull the whole file into Sonar's new-code window.
Tests: zalo 22, google_sheet 22, sdk/python 36 — all passing.

Tuần 2 of the Month-1 roadmap: the customer-service pipeline for Vietnamese
online shops.
Nhận tin -> Classify Intent -> Extract Order Info -> Fetch Order Status
-> Draft Response -> Guardrail Check -> Send hoặc Handoff
packs/ecomops/ (new):
- text.py — Vietnamese normalization. Customers routinely type without
diacritics, so both the message and the keyword lists are folded to a
diacritics-free form; "đơn hàng" and "don hang" match the same rule. đ/Đ
are handled explicitly since they don't decompose under NFD.
- intents.py — 7 EcomOps intents. RuleBasedIntentClassifier matches keyword
tokens in order allowing one filler word between them, because Vietnamese
slots pronouns inside fixed phrases ("khi nào EM nhận được hàng" must still
match "khi nao nhan"). A greeting only wins when it's the whole message, so
"chào shop, đơn em đâu" classifies as order_status. LLMIntentClassifier goes
through MagiC's own /api/v1/llm/chat gateway (cheapest routing) rather than a
provider SDK, so spend lands in the Cost Controller. HybridIntentClassifier
only pays for the LLM when the rules aren't confident, and keeps the rule
guess if the gateway is down.
- extraction.py — order code + phone. Phones are masked out before the bare
numeric order-code pattern runs, otherwise "sdt 0901234567" returns the phone
as the order id and every lookup silently misses.
- guardrails.py — an LLM draft is not automatically safe to send from a shop's
official account. Blocks leaked third-party contacts, hard delivery
guarantees, unapproved refunds/vouchers, and system-prompt/credential leaks.
Runs on normalized text so it can't be evaded by dropping diacritics.
- prompts.py — Vietnamese prompt library, kept as data so shops can retune tone
without touching pipeline code.
- workflow.py — the pipeline. Every dependency is injected, so it makes no
network calls and knows nothing about Zalo or Sheets. A blocked draft is
never returned to the caller: reply falls back to a safe message and action
becomes "handoff". Complaints skip drafting entirely.
- example_worker.py — end-to-end demo (Zalo webhook -> Sheet lookup -> guarded
reply), which is the stated Tuần 2 deliverable.
CI (this is the part that was quietly broken): the python job only ever ran
sdk/python. The 44 connector tests added in #17/#18 have never executed on CI,
and neither would these 76. Running `pytest connectors packs` from the root
failed outright because asyncio_mode lived only in per-directory pytest.ini
files — hence the new root pytest.ini. ruff was also weaker outside sdk/python
(E501/I aren't in ruff's default rule set), so a root ruff.toml now mirrors
sdk/python's settings; the 4 import-order issues that surfaced are fixed.
Tests: 76 new (packs) + 44 (connectors) + 36 (sdk) = 156, all passing. Go core
untouched, builds clean.

* fix(ecomops): canonicalize VN phone forms in the leaked-contact guardrail
Found while PR #19's CI was running: a shop that configures its hotline as
"+84987654321" (or "84987654321") had its OWN number flagged as a leaked
third-party contact, so any reply quoting the hotline was blocked and pushed to
a human. The rule compared raw digit strings, so the +84 and 0-prefixed
spellings of the same number never matched.
Adds `canonical_phone()` — folds "+84 987-654-321", "84987654321",
"987654321" and "0987-654-321" all to "0987654321" — and compares canonical
forms on both sides. Detection is unaffected: a genuinely foreign number is
still blocked (covered by a new test that allowlists the hotline and checks a
different number is still caught).
Also NOSONAR the `pip install ruff` lint line. Editing that line to widen the
lint scope made SonarCloud treat it as new code and re-apply the same two
supply-chain hotspots (S4830/S5445) already suppressed on the install lines
above it — that's what dropped this PR's Security Rating to C.
Tests: 14 new (canonical_phone table + hotline spellings + allowlist scoping),
170 total, all passing.
