Set draft sequence steps

Outcome

Replace every step of an exact draft sequence version.

Before you start

Verify the environment, credential, authorized organization and the published action permission workspace:write.
Discover an accessible Engage workspace and bind resourceType=workspace and its resourceId separately from action input. Fixture identifiers grant no access.
Approve the exact mutation and its effects before CLI --confirm or MCP confirm:true. This documentation does not authorize outreach.

Discover the target

Discover the sequence through sequences.list using the retained campaignId, then read sequences.get in the same authorized workspace. Inspect sequence.status, draft, published and versions before planning.
Select draft.id and read sequences.versions.get. Retain the complete prior ordered steps; the input replaces the entire step set rather than appending.

topolo whoami --json
topolo actions get app_topolo_engage.sequences.versions.steps.set --json
topolo workspaces list topolo-engage --json

Input fields

Field	Required	Meaning and constraints
`id`	Yes	Required sequence identifier discovered through sequences.list in the selected workspace, trimmed non-empty string up to 128 characters.
`versionId`	Yes	Required version identifier from sequences.get versions[], draft or published, trimmed non-empty string up to 128 characters. It must belong to the supplied sequence; version number is not versionId.
`steps`	Yes	Required array of 1–10 steps in execution order. Every step needs delayDays integer 0–90, relative to enrollment for the first step and previous step thereafter. Email (type omitted or email): subjectTemplate trimmed ≤200, bodyTemplate trimmed 1–10,000 and required threadWithPrevious boolean. Tasks (linkedin_task/call_task): instructions trimmed 1–2,000 and optional dueDays integer 0–30. WhatsApp: templateName lowercase letters/digits/underscore 1–512, language such as en_US, and up to 10 ordered allowed merge-field variables. Use the strict current nested schema; do not mix variant fields.

Validate, plan and execute

Set ENGAGE_WORKSPACE_ID to the identifier of your selected workspace. Prepare payload.json from the current input schema and discovered identifiers. Use the same payload for validation, planning and execution.

: "${ENGAGE_WORKSPACE_ID:?Set ENGAGE_WORKSPACE_ID to your selected workspace identifier}"
topolo actions validate app_topolo_engage.sequences.versions.steps.set --data @payload.json --json
topolo actions plan app_topolo_engage.sequences.versions.steps.set --resource-type workspace --resource-id "$ENGAGE_WORKSPACE_ID" --data @payload.json --confirm --json

Review the plan and obtain approval for the exact effects before executing the unchanged request.

: "${ENGAGE_WORKSPACE_ID:?Set ENGAGE_WORKSPACE_ID to your selected workspace identifier}"
topolo actions call app_topolo_engage.sequences.versions.steps.set --resource-type workspace --resource-id "$ENGAGE_WORKSPACE_ID" --data @payload.json --confirm --json

For MCP, use topolo_get_action, topolo_validate_action, topolo_plan_action and topolo_call_action. Pass the selected resource context separately; confirm:true is required for mutations.

Effects and response meaning

Atomically deletes and replaces the draft’s steps, assigning new step ids and positions in supplied order. Requires a non-archived sequence and draft version; published versions are immutable.
Email templates allow first_name, last_name, company, title and sender_name merge fields. Non-threaded email requires a subject; first step cannot thread and later threading requires a prior email. Saving steps performs these structural checks, not the full publish-time copy QA.
Manual LinkedIn/call task steps describe human work; WhatsApp steps reference template/language and ordered variables. Saving these steps is not provider approval, opt-in proof or delivery. Nothing is sent until separately authorized enrollment/runner work.

Verify the result

Read sequences.versions.get and compare the complete ordered content and types with the reviewed input. Expect regenerated step ids. Run sequences.copy_check for QA before a separately reviewed publish.

Recover

After an uncertain response, read the exact draft and compare all steps before retrying. Repeating set generates new step ids, and an expected-version guard is absent. Restoring retained prior contents is a separately approved full replacement only while this version is still a draft; published versions require a new draft.

Error recovery

HTTP 403 permission_denied: Stop and inspect the permission required by this action in the current credential. Do not broaden permissions or switch organization automatically.
HTTP 422 invalid_action_input: Correct required fields, enums and nested step bounds against the current input schema, then validate the exact intended payload again.
HTTP 422 invalid_steps: Inspect details.problems and the current step schema. Correct the exact draft before validating again; a version must contain steps to publish, thread rules must hold and unknown merge fields are refused.
HTTP 409 state_conflict: Read sequences.get and the exact version. Archived sequences cannot change, only one non-archived sequence per campaign and one draft per sequence may exist, and published versions cannot be edited. Re-plan only a legal, separately approved operation.
HTTP 404 not_found: Rediscover the sequence using sequences.list in the same workspace and campaign; use status=archived when needed. Discover versionId from sequences.get and confirm it belongs to the same sequence. Do not guess another workspace or version.

Actual route handlers with SQLite repositories; synthetic identity/workspace grants and provider ports.
Widget/bootstrap use actual app handler but mocked worker runtime and app identity.
No gateway execution, live permissions, external delivery or deployed proof.

The examples are local route captures with synthetic context and simulated providers. They do not prove live authorization, CLI/MCP gateway execution, production state or delivery.
