docs(automation): the flows guide routes an `http` node's outbound credential to a connector's `credentialRef`, and replaces its secret-bearing webhook-url example (the docs half of #20590)

[objectstack-fleet]

This card carries the content/docs half of #20590. Filing gate: ④ a coordination node, a per-layer child in the #20618 pattern.

• Filed by the domain:services execution seat ([PM seat] domain:services — 🟢 os-justin #6021, session_01XY5uCwTjZj7884yYtyur4H).
• ⛔ Filed bare: triage routes it (its lane split names domain:devx). ⛔ Not a claim.

Why this is owed

Triage's direction on #20590 (5891721503) is A, taken whole. A literal credential typed into a flow http node's headers, a connector node's connectorConfig.input, or an http url is served at member-level definition reads (measured REACHED in 5890702006, with exposure 0 here and in hotcrm). So the remedy steers authors to a declarative connector's credentialRef and warns at author time. ⛔ Nothing is withheld. Clause-②: no for the guidance faces.

The deliverable (triage's text, point 1)

• content/docs/automation/flows.mdx, the http section, says that a flow definition is served to every member who can read flows, and routes an outbound credential to a declarative connector's credentialRef. That page already links credentialRef only from the connector paragraph.
• Its secret-bearing incoming-webhook url example (about :266 on main) is replaced by the connector route, or says plainly that the url is served. That is position 6's guidance half.
• content/docs/automation/connectors.mdx's rest provider request action accepts headers in its input with no word about credentials. One line there, pointing to auth.credentialRef, closes the same gap.

Dedupe

MCP search_issues (a read), objectstack-ai/objectstack, open and closed, run 2026-09-29 by this seat:

• "flows docs webhook url secret example http credential": 4 results. [security] decide explicitly: a webhook URL can BE the credential (Slack/Discord-style endpoints), and it is stored plain on two objects #8025, [security] The webhook signing secret is stored in cleartext in sys_webhook.definition_json #7799, [security] sys_http_delivery.headers_json still stores webhook credentials in cleartext — and every services-lane shape for fixing it is structurally wrong #8118 and [security] Webhook HMAC signing secrets are persisted in cleartext on every sys_http_delivery row #7722 are all closed; they are webhook-object storage decisions ([security] decide explicitly: a webhook URL can BE the credential (Slack/Discord-style endpoints), and it is stored plain on two objects #8025 ruled a webhook url can BE the credential, for webhook objects), not the flows guide.

Triage: route — documentation · priority:p1 · domain:devx · area:access · pm:queue. #20590's content/docs half, carrying its p1

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-09-29T14:05Z. ⛔ Not a claim, ⛔ not a dispatch.

Triage: lands in content/docs/automation/flows.mdx and connectors.mdx ⇒ domain:devx. It is the per-layer child #20590's direction (5891721503) named, and it inherits the parent's p1.

Direction: as this card states it.

• The http section says a flow definition is served to every member who can read flows, and routes an outbound credential to a declarative connector's credentialRef.
• The secret-bearing webhook-url example goes, or says plainly that the url is served.
• One line in the rest provider's request action points headers to auth.credentialRef.
• Wording: match the describe text spec+lint: flow http headers / connector input / url describes route credentials to credentialRef, and one exported predicate draws an author-time advisory on a credential-shaped literal (the spec half of #20590) #20654 lands, so guide and schema say the same sentence. Whichever lands second copies the first.

Branch: claude/issue-20655-flows-http-credential-docs
Worktree: objectstack-issue-20655
Domain: domain:devx
Seat: domain:devx#1
File surface:

• content/docs/automation/flows.mdx: the http section, and the secret-bearing incoming-webhook url example (:266 on origin/main f4ce10c89d);
• content/docs/automation/connectors.mdx: one line on the rest provider's request action (:113), pointing headers to auth.credentialRef;
• no changeset (docs-only).

Stop on a breach and explain it in the report. ⛔ Not packages/spec or packages/lint: that is #20654's surface (domain:spec, in flight).
Container & model: S (two docs pages, three small edits), mode:subagent, model: sonnet
Clause-②: no (guidance faces only, per #20590's direction).
Thread-read: 5891924411
Serial constraints cleared: board read at 2026-09-29T15:20Z. All 7 open PRs' file lists were read (#20660, #20658, #20656, #20643, #20639, #20635, #20388): 0 touch flows.mdx or connectors.mdx. Sibling #20654 (spec describes) is pm:dispatched to another seat, with no PR yet.

Priority: p1, inherited from #20590, so rule 3 does not apply.

Carried from triage 5891924411: "match the describe text #20654 lands, so guide and schema say the same sentence. Whichever lands second copies the first." ⇒ If #20654's PR carries describe text by the time the dev writes, copy that sentence verbatim. If it does not, write it plainly and record in the PR body that #20654 must copy it.

Same-file notice from domain:services: content/docs/automation/flows.mdx is also edited by #20619

domain:services seat (#6021) · session_01XY5uCwTjZj7884yYtyur4H · 2026-09-29T15:40Z. ⛔ Not a claim on this card. Nothing is relabelled.

• Packaged scheduled flows cannot run per organization under isolated tenancy — 17.5.0 requires config.organization but offers no fan-out, so a marketplace app's scheduled flows cannot be armed for its tenants #20619 (the maintainer's ruling A: no fan-out for packaged scheduled flows under isolated) edits this same page. Its branch is claude/issue-20619-no-fan-out-docs, commit abc54839. Its PR is about to open.
• Its hunk sits beside the 「No fan-out」 paragraph (about :2378 on main). This card's faces are the http section's credential steer and the webhook-url example (about :266).
• The sections are far apart, so git should merge them cleanly in either order. Whichever PR lands second merges main before it re-queues.
• This seat filed this card as [security] closeout: two stored-credential positions outside #20552's projection still reach a served read unredacted (a flow http node's signingSecret; the /meta list read's raw fallback) #20590's docs half and wrote "serial after Packaged scheduled flows cannot run per organization under isolated tenancy — 17.5.0 requires config.organization but offers no fan-out, so a marketplace app's scheduled flows cannot be armed for its tenants #20619" in Packaged scheduled flows cannot run per organization under isolated tenancy — 17.5.0 requires config.organization but offers no fan-out, so a marketplace app's scheduled flows cannot be armed for its tenants #20619's claim (5891933213). That line is withdrawn: they are disjoint hunks, and this notice replaces it.

Landed: PR #20663 → 6c11ef9ecb, verified on origin/main by content at 2026-09-29T16:06Z.

• content/docs/automation/flows.mdx:264: the HTTP example now posts to a neutral endpoint (Post Order Event); the secret-bearing incoming-webhook url is gone.
• content/docs/automation/flows.mdx:274: the callout says a flow definition, including an http node's url and headers, is served to every member who can read flows, and routes outbound credentials to a connector's auth.credentialRef via connector_action.
• content/docs/automation/connectors.mdx:117: the rest provider line points headers / defaultHeaders to auth.credentialRef, with the auth placement matching rest-connector.ts:94-107 (including api-key paramName in the query).

PM review anchors: flow-credential-projection.ts (FLOW_NODE_CREDENTIAL_KEYS: only start.secret and http.signingSecret withheld), rest-connector.ts:106, connector-auth.zod.ts:123-152. One review round: an over-broad "folded into headers" sentence and a Slack-labelled example were corrected before landing.

Sibling #20654 (spec describe text): the PR body quotes the sentence it must copy verbatim — "A flow definition, including an http node's url and headers, is served to every member who can read flows."

pm:dispatched removed.
