Create your first rule — step-by-step

/rules → New rule. The builder walks through 9 steps. New rules start with status paused — use preview first, then toggle to active. Allow the first evaluation tick (up to 15 min) before expecting execution.

Who is this for

First-time rule builders. Anyone porting a manual workflow ("every morning I pause adsets with CPA > 30") into an automated rule.

Prerequisites

• Active ad account connected (Meta / Google / TikTok / Taboola / Snapchat / Outbrain per connect cluster; Snapchat is currently behind a production flag that is off)
• At least 7 days of insights data (rules need history to evaluate against)
• Mediabuyer role or higher

How to create

Step 1: Open the builder

Sidebar → Rules → New rule. Or /rules/new directly.

Step 2: Name + description

Required. Use a descriptive name: Kill losers — CPA > 30 / 7d is better than Rule 1. Description is internal-only (your team sees it).

Step 3: Entity level

Pick one:

• Campaign — evaluate campaign-level metrics, act on campaigns
• Ad set — adset-level (more granular)
• Ad — per-ad (most granular)

The level determines which entities the rule scans + which it acts on. Most rules sit at adset level — granular enough to act, coarse enough to be meaningful.

Step 4: Scope — accounts + entity filter

Pick ad accounts (multi-select). Then narrow further:

• name contains — only entities matching pattern
• name does not contain — exclude pattern
• status in — [active, paused, archived]. No default: if you leave status_in empty, the rule evaluates entities in all statuses; set it explicitly (e.g. [active]) to narrow.

Use cases: only act on a specific client by name prefix; exclude test campaigns; only scan active.

Step 5: Conditions

Add one or more conditions:

metric  operator  value  time_rangeroas    lt        1.5    last_7dspend   gt        50     last_7d

Combine with AND (all must match) or OR (any matches).

Available metrics: see Available metrics for rule conditions. Operators: see Conditions, operators, time ranges.

Step 6: Actions

Pick one or more actions:

For budget actions, set the % delta. Platform minimums apply (Google campaign $1, TikTok campaign $50, TikTok adset $20, others $2).

Step 7: Schedule

Three schedule types:

• Interval — every N minutes (effective cadence bounded by the 15-min cron; the schema default for interval_minutes is 30)
• Daily at time — once per day at HH:MM in the rule's timezone
• Day-parting — evaluate only during chosen days-of-week + hours-of-day (with a timezone)

Most rules use interval. Daily-at-time is for end-of-day kills / start-of-day scales.

Step 8: Protections

Set the safety net:

• Cooldown minutes — default 360 (6h), min 60 for destructive actions. Per-entity check within window.
• Max executions per day — default 3, hard cap 50. Prevents runaway.
• Budget change limit % — single-action cap field. Configurable but not yet enforced at execution time (enforcement is coming) — don't rely on it as a hard cap.
• Budget daily cap — cumulative daily delta cap field. Same status: configurable, enforcement coming.

See rul-108 protections for deep dive.

Step 9: Notifications

notify_on_execution toggle + channels: in_app, telegram, email.

Channel availability:

• in_app — always available
• telegram — requires bot connected (see Customize notification preferences)
• email — sent to billing email by default

Step 10: Save (status = paused)

Click Save. The rule is created with status paused.

Step 11: Preview before activating

/rules/:id → Preview button. It returns:

• entities_evaluated — total scanned
• entities_matched — matched the conditions (with metric values shown)
• entities_skipped — why (cooldown, daily cap, pending)

Check the matches make sense. If scope is too broad or too narrow, edit + preview again.

Step 12: Activate

Once preview is clean: per-rule actions menu → Activate. The rule flips to status active.

Next cron tick (within 15 min): rule evaluates for real. Watch execution history to confirm behavior.

What a rule captures

A rule captures:

• Name and description
• Entity level: campaign / adset / ad
• The ad accounts and entity filter it targets
• Condition logic (AND / OR) and one or more conditions (metric, operator, value, time range)
• One or more actions (type + parameters)
• Schedule type and cadence
• Protections: cooldown, max executions per day, budget change limit %, daily budget cap
• Notification settings (whether to notify on execution and on which channels)
• Platforms (default Meta)

The rule is created paused.

RBAC + audit

Mediabuyer+ can create rules. Audit log entry: action: rule.create recorded in the audit log with metadata (rule id, name, scope).

Common issues

• "Save button disabled": a required field missing — usually scope (no ad account selected) or conditions empty.
• "No entities matched in preview": scope too narrow OR condition thresholds too strict for current data. Loosen + re-preview.
• "Too many matches": scope too broad — add filters, raise thresholds, drop a condition.
• "Activated rule never fires": see rul-118 troubleshooting.

FAQ

What do I need before creating my first rule?

Three prerequisites in Wevion: an active ad account connected (Meta, Google, TikTok, Taboola, Snapchat, or Outbrain), at least 7 days of insights data for the rule to evaluate against, and the mediabuyer role or higher. Without history the rule has nothing to measure, so wait until data has accumulated.

Why is the Save button disabled in the rule builder?

A required field is missing — most often the scope (no ad account selected) or empty conditions. Wevion's rule builder blocks Save until required fields are complete. Select at least one ad account, add at least one condition, and give the rule a name and description to enable Save.

How do I test a rule before it changes anything?

Use preview. After saving (rules start paused), open /rules/:id and click Preview. It shows the entities evaluated (total scanned), those matched (with metric values shown), and those skipped (with reasons). Confirm the matches make sense, then activate. If scope is too broad or narrow, edit and preview again.

Why doesn't my rule fire immediately after I activate it?

Activation flips the rule to status active, but Wevion evaluates on a scheduled cadence. The rule runs for real on the next evaluation tick, within 15 minutes. Watch the execution history to confirm behavior. If it still never fires, see the rules troubleshooting article.

Who can create rules in Wevion?

Creating rules requires the mediabuyer role or higher. When you save, Wevion records the rule and writes an audit log entry (rule.create) with metadata including rule id, name, and scope. Lower roles cannot create or edit rules.
