Systeme.io platform help — budget all-in-one for bootstrappers and solopreneurs (systeme.io): sales funnels + website, email marketing, online courses, community + booking, CRM pipelines + automation, affiliate management, automated webinars, and a genuinely usable free plan. Covers the REST API (base api.systeme.io, X-API-Key header, contacts/tags/funnels/orders/subscriptions/webhooks endpoints, cursor pagination, 429 rate-limit headers) and webhook events. Use when building a Systeme.io API integration to sync contacts or tags into a CRM, working around its small native-integration ecosystem with the API or Zapier, emails arriving late or going to spam, the drag-and-drop page builder feels restrictive, setting up a webhook for new-sale or tag events, hitting 429 rate limits, migrating in from another tool, or choosing a plan (Free vs Startup vs Webinar vs Unlimited). Do NOT use for funnel strategy across tools or comparing Systeme.io against other all-in-one platforms (use /sales-funnel).

Systeme.io Platform Help
Step 1 — Gather context
If references/learnings.md exists, read it first for accumulated platform knowledge.
What are you trying to do?
A) Build a REST API integration — sync contacts/tags, read funnels/orders/subscriptions, manage webhooks
B) Set up a webhook — react to contact created, tag added/removed, new sale, or sale canceled
C) Configure a module inside Systeme.io — funnels/pages, email + automation, courses, community, affiliates, webinars
D) Pick a plan — Free vs Startup vs Webinar vs Unlimited
E) Fix a problem — email deliverability, page-builder limits, missing native integration, migration, rate limits
F) Something else — describe it
Where does data need to flow? Stay inside Systeme.io / sync to a CRM or warehouse / drive an external app — this decides API vs webhook vs Zapier.
Skip-ahead rule: if the user's prompt already provides enough context, skip to Step 2.
Step 2 — Route or answer directly
If the question is about...
Route to...
Multi-step funnel strategy/structure across tools
/sales-funnel {question}
Email-marketing strategy and sequences
/sales-email-marketing {question}
Email deliverability / inbox placement
/sales-deliverability {question}
Course / membership / community structure and retention
/sales-membership {question}
Automated / evergreen webinar funnel strategy
/sales-webinar {question}
Affiliate-program design across tools
/sales-affiliate-program {question}
Comparing Systeme.io vs other all-in-one platforms
/sales-funnel {question}
When routing, give the exact command, e.g. "This is a deliverability question — run: /sales-deliverability {your question}".
Step 3 — Systeme.io platform reference
Read references/platform-guide.md for the full reference — the module map (what's API-accessible vs webhook-accessible vs UI-only), the free-plan limits and plan gates, the contact/tag/order data model with JSON shapes, and quick-start recipes (create a contact + assign a tag via the API; register a new-sale webhook; paginate contacts into a warehouse).
Read references/systemeio-api-reference.md for the REST API — base https://api.systeme.io, the X-API-Key auth, the resource endpoints (contacts, tags, funnels, products, subscriptions, campaigns, orders, webhooks), cursor pagination (startingAfter + limit), the rate-limit headers, and the webhook event list.
Answer the user's question using only the relevant section. Don't dump the full reference.
Step 4 — Actionable guidance
Focus on the user's specific situation:
The API is the answer to the small integration ecosystem. Systeme.io has fewer native connectors than GoHighLevel/ActiveCampaign — when a native integration is missing, the public REST API (or Zapier/Make/Pabbly/n8n) is the supported path. The API is available across plans, including Free.
Auth with X-API-Key. Generate a key in profile settings → Public API keys (max 3, each with a name + expiry). Pass it in the X-API-Key header (Bearer also accepted).
Paginate with the cursor. List endpoints use startingAfter (the ID of the last item you saw) + limit — not page numbers. Loop until a short page comes back.
Respect the rate limit. Watch X-RateLimit-Remaining; on 429, honor Retry-After and back off. Don't hammer list endpoints in tight loops.
Use webhooks for sales events (new sale, sale canceled, tag added) instead of polling /api/orders — lower latency and cheaper on the rate limit.
Deliverability is on you. Systeme.io sends are only as good as your list hygiene and authentication — warm up, authenticate your domain, and avoid cold/purchased lists to keep out of spam.
If you discover a gotcha, workaround, or tip not covered in references/learnings.md, append it there.
Gotchas
Best-effort from research (2026-06) — review these, especially plan-gated features and pricing, which change frequently.
Small native-integration ecosystem. Far fewer one-click connectors than competitors — plan to use the public API, Zapier/Make/Pabbly/n8n, or webhooks for anything non-native. This is the most common structural complaint.
Page builder is intentionally simple. The drag-and-drop editor trades design flexibility for ease — users coming from Leadpages/Unbounce find it restrictive and occasionally buggy. Set expectations; don't promise pixel-perfect control.
Email templates are basic. Great for plain, deliverable text emails; weak for heavily designed HTML. If a brand needs rich templates, flag the limitation early.
Deliverability can be inconsistent — delayed or filtered sends show up in reviews. Authenticate the sending domain, warm up, and keep complaint rates low.
Cursor pagination, not pages. Use startingAfter + limit; assuming ?page=2 will silently miss records.
Migration takes longer than expected. Free migration is offered on the Unlimited plan, but timelines run long — budget extra time when switching in.
API keys expire. Keys are created with an expiry date — a silently-expired key looks like an auth bug. Rotate before expiry.

Examples
Example 1: Sync new signups into Systeme.io and tag them (developer/automation)
User says: "When someone signs up in my app I want to create the contact in Systeme.io and tag them 'app-trial'. What API calls?"
Skill does: Shows POST https://api.systeme.io/api/contacts with the X-API-Key header and {"email": "..."} to create (upsert by email), then assigns the tag via the tags endpoint (Recipe 1 in references/platform-guide.md). Notes the tag must exist (create it once with POST /api/tags), and to watch X-RateLimit-Remaining.
Result: User has a create-contact-then-tag flow and understands the key + rate-limit handling.
Example 2: Fire fulfillment the instant someone buys (developer)
User says: "I want a webhook when someone makes a purchase in Systeme.io, not a polling job."
Skill does: Points to registering a webhook (via POST /api/webhooks or the dashboard) on the new sale event, describes the payload, and explains responding 2xx fast + deduping since deliveries can repeat (Recipe 2). Contrasts with polling /api/orders, which burns the rate limit.
Result: User sets up an event-driven webhook instead of a cron.
Example 3: My emails are landing in spam
User says: "Half my Systeme.io broadcasts go to promotions or spam. How do I fix it?"
Skill does: Explains Systeme.io deliverability depends on domain authentication and list hygiene, then routes: "This is a deliverability problem — run: /sales-deliverability my Systeme.io emails are going to spam." Adds Systeme.io-specific first steps: authenticate the sending domain, send plain-text-leaning emails (the editor favors them), and suppress unengaged contacts.
Result: User gets platform context plus the right strategy skill.
Troubleshooting
API returns 401 Unauthorized
Symptom: Requests fail even with a key that worked before.
Cause: The X-API-Key header is missing/misspelled, the key has hit its expiry date, or it was deleted (max 3 keys per account).
Solution: Confirm the X-API-Key header is set; regenerate the key in profile settings → Public API keys with a fresh expiry; update the integration. Bearer-token auth is also accepted if you prefer the Authorization header.
Hitting 429 Too Many Requests
Symptom: Bulk syncs start returning 429s.
Cause: You've exceeded the request budget shown in the X-RateLimit-* headers.
Solution: Read X-RateLimit-Remaining and slow down before you hit zero; on 429, honor the Retry-After header and back off exponentially. Batch work, cache lookups, and paginate with startingAfter rather than re-fetching whole lists.
A native integration I need doesn't exist
Symptom: The tool you want to connect isn't in Systeme.io's integrations list.
Cause: Systeme.io's native ecosystem is small by design.
Solution: Use the public REST API directly, or bridge through Zapier/Make/Pabbly/n8n, or set up a webhook (new sale, tag added) to push events to your own endpoint. For CRM sync, the /api/contacts + /api/tags endpoints plus webhooks cover most flows.
