API-Triggered Campaigns (Backend → Clix)

Use this skill to set up API-triggered campaigns in the Clix console and trigger them from your backend with dynamic data (trigger.*) for:

• Transactional notifications (orders, password reset, receipts)
• Workflow messages (assignments, approvals)
• System alerts (moderation, support tickets)
• Programmatic sends where marketers/ops should control content + targeting

What the official docs guarantee (high-signal)

• API-triggered campaigns are configured in the console, then triggered via: POST /api/v1/campaigns/{campaign_id}:trigger
• Authentication uses secret headers:
  • X-Clix-Project-ID
  • X-Clix-API-Key
• Request properties become trigger.* for:
  • Dynamic audience filtering (console audience rules)
  • Personalization in templates (title/body/deep links)
• audience.broadcast=true sends to all users eligible under the campaign’s segment definition; audience.targets narrows to specific users/devices (still filtered by the segment definition).
• Dynamic audience filters are intentionally constrained for performance: max 3 attributes in the audience definition.

MCP-first (source of truth)

If Clix MCP tools are available, treat them as the source of truth:

• Use clix-mcp-server:search_docs to confirm the latest API contract + limits:
  • query examples:
    • "API-triggered campaign trigger endpoint"
    • "campaigns/{campaign_id}:trigger audience targets broadcast"
    • "trigger.* dynamic audience filters limitations"

If MCP tools are not available, use the bundled references:

• API contract → references/api-contract.md
• Console setup + dynamic filters → references/console-setup.md
• Backend patterns (auth, retries, timeouts) → references/backend-patterns.md
• Security/key handling → references/security-and-keys.md
• Personalization + dynamic filters → references/personalization-and-dynamic-filters.md
• Debugging checklist → references/debugging.md

Workflow (copy + check off)

API-triggered campaign progress:
- [ ] 1) Confirm goals + trigger source (what backend event sends the message?)
- [ ] 2) Define campaign contract (properties keys/types; PII policy)
- [ ] 3) Configure campaign in console (API-triggered + audience rules + templates)
- [ ] 4) Implement backend trigger wrapper (auth, timeout, retries, logging)
- [ ] 5) Validate trigger plan JSON (schema + naming + safety)
- [ ] 6) Verify in Clix (test payloads, Message Logs, segment matching)

1) Confirm the minimum inputs

Ask only what’s needed:

• Campaign: where is it in the console? do you already have campaign_id?
• Channel: push / in-app / email / etc. (affects message template fields)
• Audience mode: broadcast vs explicit targets
• Dynamic filter keys: which trigger.* keys are used in audience rules
• Properties: list of keys + types + example values (avoid PII by default)
• Backend: runtime and HTTP client (Node/Fetch, Axios, Python, Go, etc.)

2) Create a “Trigger Plan” (before touching backend code)

Create api-trigger-plan.json in .clix/ (recommended) or project root.

Recommended location: .clix/api-trigger-plan.json

Plan schema (high-level):

• campaign_id (string)
• audience.mode: "broadcast" | "targets" | "default"
• audience.targets (if mode is "targets")
• dynamic_filter_keys (array of up to 3 snake_case keys)
• properties (map of snake_case keys → { type, required?, example?, pii? })

Example:

{
  "campaign_id": "019aa002-1d0e-7407-a0c5-5bfa8dd2be30",
  "audience": {
    "mode": "broadcast"
  },
  "dynamic_filter_keys": ["store_location"],
  "properties": {
    "store_location": {
      "type": "string",
      "required": true,
      "example": "San Francisco"
    },
    "order_id": { "type": "string", "required": true, "example": "ORD-12345" },
    "item_count": { "type": "number", "required": true, "example": 3 },
    "pickup_time": { "type": "string", "required": false, "example": "2:30 PM" }
  }
}

3) Configure campaign in the console (API-triggered)

• Set the campaign type to API-Triggered.
• Build audience rules using {{ trigger.* }} for dynamic filters.
• Use {{ trigger.* }} in message templates + deep links.

See: references/console-setup.md for exact guidance and limitations.

4) Implement backend trigger wrapper (best practices)

Backend wrapper responsibilities:

• Auth: load X-Clix-Project-ID and X-Clix-API-Key from environment/secret store (never commit).
• Timeout: set a short timeout (e.g., 3–10s) and fail fast.
• Retries: retry only on transient failures (network/5xx), with backoff; do not retry blindly on 4xx.
• Dedupe: prevent double-sends in your system (e.g., unique key per order event) since the API call is “send-like”.
• Logging: log campaign_id, your correlation id (order id), and the Clix response (e.g., trigger_id).

Copy/paste examples:

• Node: examples/trigger-campaign-node.js
• Python: examples/trigger-campaign-python.py

5) Validate the plan (fast feedback loop)

Run:

bash <skill-dir>/scripts/validate-api-trigger-plan.sh .clix/api-trigger-plan.json

This validator checks:

• valid JSON
• campaign_id present
• dynamic_filter_keys is ≤ 3 and snake_case
• properties keys are snake_case and have valid types
• example values match declared types
• targets entries specify exactly one of project_user_id or device_id

6) Verify (Clix + end-to-end)

Minimum verification:

• Campaign is API-Triggered and campaign_id matches.
• If using dynamic audience filters, the trigger.* keys exist in the API call and match audience rules exactly.
• Trigger once with a known-good payload; confirm delivery + inspect Message Logs for rendering errors.
