Conversation
Every external-API test authenticates with the same hardcoded token, and ApiKeyRateThrottle keys its request history on that token in the Django cache. The cache is a real Redis and is not rolled back with the database, so the history accumulates across the whole session until the suite crosses API_KEY_RATE_LIMIT (60/minute) and later tests fail with 429s unrelated to what they assert. That makes the suite order- and size-dependent: adding tests anywhere can break unrelated ones further down, which is exactly what happens when the API notification coverage in the next commit is added. Clear the bucket around each test so the limit is per-test, which is what these tests already assume.

📝 WalkthroughWalkthroughThe REST API now includes notification delivery and application origin data in issue, link, and comment activity tasks. Comment creation preserves the saved comment ID for downstream processing. Contract tests verify dispatch data, and shared fixtures isolate API token throttling. ChangesREST notification parity
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to REST API writes now notify subscribers and send email, but affected endpoints can still accept caller-supplied actors without demonstrated authorization; a project member could misattribute changes and alter who is excluded from notifications, making audit history and delivery misleading. Merge should wait for actor validation or explicit maintainer acceptance. Possibly related PRs

makeplane#9307 fixed notifications for work items created or updated through the external REST API, but the same omission was left on every other write path in plane/api/views/issue.py: comment create/update/delete, link create/update/delete and work item delete dispatched issue_activity without notification=True. The flag is what gates notifications.delay(...) in issue_activities_task, so those paths recorded activity and fired webhooks while subscribers were never notified and no email was sent. Commenting through the API was therefore silent, while the identical action in the web app notified normally — plane/app/views/issue passes notification=True on all of these paths. Pass notification=True and origin=base_host(...) on the seven remaining sites so the external API matches the web app. Notification fan-out already excludes the actor and is limited to active project members and issue subscribers, and the deliberate opt-outs upstream (bulk update endpoints) are left untouched. Adds contract tests for all seven paths, matching the shape of the ones added with makeplane#9307.

The v1 comment create endpoint built requested_data from IssueCommentCreateSerializer, a write serializer that carries no id. So create_comment_activity stored the activity with issue_comment_id=None, and notification_task -- which gates all comment-mention extraction on that field being set -- skipped mentions entirely. The effect is that an @mention inside a comment created through the API notifies nobody, even with notification=True passed. Comment updates are unaffected, because update_comment_activity reads the id out of current_instance, which is serialized with the full IssueCommentSerializer. That asymmetry is what makes this specific to creates. Serialize the saved comment instead, matching the update path and the web app.

Summary
Follow-on to #9307 / #9306. That fix made work items created or updated through the
external REST API notify subscribers. The same omission was left on every other write
path in
plane/api/views/issue.py.issue_activity.delay(...)was dispatched withoutnotification=True, and that flagis what gates
notifications.delay(...)inissue_activities_task. So these pathsrecorded activity and fired webhooks while subscribers were never notified and no email
was sent.
comment.activity.createdcomment.activity.updatedcomment.activity.deletedlink.activity.createdlink.activity.updatedlink.activity.deletedissue.activity.deletedThe user-visible effect: commenting through the API is silent, while the identical
action in the web app notifies normally —
plane/app/views/issue/*passesnotification=Trueon all of these. After this change all 14issue_activity.delaysites in the file are consistent.
Also worth noting:
notification_taskauto-subscribes the actor to the work item insidethe notification path, so an API comment never subscribes its author either — they then
miss subsequent activity on that item as well.
Verified on a live instance
Traced before writing the fix, to rule out configuration: SMTP healthy, notification
preferences on, 74 items subscribed, and the mail log showed delivery for reactions on
the same work item — but zero notifications for 14 comments posted through the API that
day. The dispatch never asks for a notification, so no configuration produces one.
Question for maintainers — how should bulk/sync callers opt out?
This is the part I would most like guidance on, and I have deliberately not guessed.
These paths now notify unconditionally:
notification=Trueis hardcoded at the call site,matching the web app and #9307. There is no per-request opt-out and an API client cannot
influence it.
Ongoing integration traffic seems fine —
notification_taskexcludes the actor, so a botcommenting under its own token never notifies itself, recipients are limited to active
project members and subscribers, and email is already batched by
stack_email_notification. The case I am unsure about is a bulk backfill: importinghistorical comments through the API would notify every subscriber once, with no way to
suppress it. The web app never hits this because it is human-paced.
Upstream already draws this distinction —
IssueBulkUpdateDateEndpointinapp/views/issue/base.pyomits the flag deliberately — but there is no equivalent signalon the external API. Two candidates that need no new public surface:
external_source/external_id— already writable onIssueCommentSerializer.A comment carrying these is by definition a mirrored record from another system rather
than a fresh human action, which maps closely onto the import case.
APIToken.user_type == Bot/is_service— already first-class on the model.Neither is obviously right: (2) would also suppress genuine bot activity that subscribers
probably do want (a CI bot posting "build failed" on an item you watch). (1) only helps
clients that populate those fields.
Happy to implement whichever you prefer, in this PR or a follow-up — or to leave strict
parity as-is if you consider the backfill case out of scope.
Tests
test_comment_link_notifications.pycovers all seven paths, following the shape of thetests added with #9307. They assert the dispatch contract rather than delivery, since
notification=Trueis the gate and the fan-out is covered downstream — which keeps themoff Celery.
Verified red/green: with the source change reverted all 7 fail with
KeyError: 'notification'; with it applied all 7 pass.Full suite, run twice each against an isolated Redis:
previewSame 12 pre-existing failures, +7 new tests, no regressions.
The second commit is separable
test: reset the shared api-key throttle bucket between testscan be dropped if you wouldrather solve it differently, but the new tests fail without it.
Every external-API test authenticates with the same hardcoded token, and
ApiKeyRateThrottlekeys its request history on that token in the Django cache — a realRedis, not rolled back with the database. The history accumulates across the session until
the suite crosses
API_KEY_RATE_LIMIT(60/minute), after which later tests fail with 429sunrelated to what they assert.
That makes the suite order- and size-dependent: adding tests anywhere can break unrelated
tests further down. Adding the 7 tests above broke 5 in
test_projects.py/test_projects_lite.pythat pass in isolation. Clearing the bucket around each test makesthe limit per-test, which is what these tests already assume.
