Systeme.io Integrations - Native Apps, Zapier, Webhooks and the API (2026)

Systeme.io has a short list of native integrations, by design. Its pricing table lists Google Sheets, Google Calendar, Google Meet, Zoom, ActiveCampaign, SendGrid and Twilio SMS, plus payment gateways including Stripe, PayPal, Razorpay, Flutterwave, Mercado Pago and Xendit. Everything else connects through Zapier, webhooks, the public API or embed code, and a newer MCP server links AI assistants such as ChatGPT and Claude.

That short list is deliberate: Systeme.io builds email, funnels, courses, booking and affiliate tools into one account, so it needs fewer connections than a stack of separate apps. The native integrations appear on every plan, including Free. This guide covers each option, how to set it up and when you need something else.

Systeme.io Integrations at a Glance

Native Integrations

Native integrations live under profile picture, Settings, Integrations. Each one opens a connect window and then shows as connected, with options to view details or disconnect.

Google Sheets

The Google Sheets integration adds the workflow action Add a new row to a Google Sheet, so sales, opt-ins or tags can log a row with no Zapier step. Two limits from the help center: it works only in workflows, not automation rules, and the sheet must already have column headers. You can connect more than one Google account and map several fields into one column.

Google Calendar and Google Meet

Google Calendar syncs events from Systeme.io's booking calendar to your default calendar. Connecting Calendar also connects Google Meet by default, so bookings can include a Meet link. Meet cannot be connected on its own.

Zoom

Zoom connects to the booking calendar. When you set an event's location to an online meeting on Zoom, people who book receive the Zoom link by email. The help center lists a free Systeme.io account as enough for this integration.

ActiveCampaign

The ActiveCampaign integration is one-way. It syncs contacts and tags from Systeme.io on three triggers, contact created, tag added and tag removed, and creates missing tags in ActiveCampaign. Changes made in ActiveCampaign do not flow back. You need your ActiveCampaign API URL and key.

SendGrid

You can send campaigns and newsletters from Systeme.io through your own SendGrid account. That needs a domain, DNS access and a SendGrid API key. Most users do not need it, since Systeme.io sends email itself.

Twilio SMS

Systeme.io's SMS runs through your own Twilio account. Paste your Twilio Account SID and Auth Token, and SMS becomes an action in automation rules and workflows. Your Twilio number must be messaging-enabled for the countries you text, and Twilio bills each message.

Payment Integrations

Payments connect under Settings, Payment gateways. The pricing table lists Stripe, Apple Pay, PayPal, Razorpay, Flutterwave, Mercado Pago, Xendit and cash on delivery, and the help center adds guides for Mollie, GoCardless and Apple Pay through Stripe.

Systeme.io charges 0% transaction fees on every plan; your gateway's own fees still apply. More detail is in the Systeme.io pricing guide.

Zapier Integration

Zapier is the main route to apps without a native connection. Zapier's systeme.io app lists these events:

Common uses: adding Typeform, Tally or Jotform entries as tagged contacts, granting course access after a sale on another checkout, and copying contacts to an outside email tool such as GetResponse or Brevo, which the help center names as Zapier options. Zapier is billed separately by Zapier.

Webhooks

Webhooks send event data to any URL as an HTTP request in JSON, which is useful for custom tools, automation platforms and developers. Systeme.io offers two ways to send them.

Webhooks From Rules and Workflows

Add the Send webhook action to an automation rule or workflow and paste the destination URL. The help center documents the JSON for events such as an opt-in ("contact.optin.completed") and a new sale ("customer.sale.completed"), and lists the IP addresses requests come from.

Account-Level Webhooks

Under Settings, Webhooks, Create, you add a name, an HTTPS endpoint and a secret key, then choose events:

• Contact created
• Contact tag added
• Contact tag removed
• Opt-In
• New sale (funnels and creator stores)
• Sale canceled

Each webhook has message and delivery logs. If your server is down, Systeme.io retries up to 12 times, with up to about 24 hours between attempts.

The Public API

The public API is for developers and no-code builders who need more than Zapier's events. Keys are created under Settings, MCP and API keys, Public API keys, with an optional expiry date. You can hold up to three API keys, a key can only be copied right after it is created, and Systeme.io emails you whenever a new key is made.

According to the help center, the API covers:

• Contacts, tags and custom fields
• Newsletters, email campaigns and email statistics
• Funnels, including creating opt-in and webinar funnels
• Price plans, coupons, offers and digital and physical products
• Courses, modules, lectures and communities
• Automation rules, webhooks and subscriptions
• Booking calendar events and SMS templates

MCP Server for AI Assistants

Systeme.io also runs an MCP (Model Context Protocol) server, which lets AI assistants act on your account in plain language, such as finding a contact or adding a tag. You create an MCP key in the same MCP and API keys screen, then follow the help center's guides for connecting ChatGPT or Claude. Help articles cover contacts, newsletters, funnels, price plans, automation rules, products and the booking calendar. Review what an assistant is allowed to change before giving it a key.

Embeds, Tracking Codes and External Sites

Not every connection needs an integration:

• Calendly, TidyCal and YouCanBook.me: paste the embed code into a Raw HTML element on a funnel page.
• Meta Pixel: paste it into a page's header code or into the funnel-wide tracking code under Settings, Sales funnel.
• Meta Conversions API: a help guide covers server-side event setup.
• Forms on other websites: create an inline form or popup step, click Script and paste the code on WordPress or any site.
• Custom HTML, CSS and JavaScript: header, footer, tracking code or Raw HTML elements.

Which Integration Method Should You Use?

Systeme.io Integration Limits to Know

• No native CRM sync with tools such as HubSpot or Salesforce; use Zapier or the API.
• ActiveCampaign is one-way only.
• Google Sheets rows work in workflows, not rules.
• Workflow and rule caps on lower plans limit how much you can automate. Per Systeme.io's plan data, Free includes 1 automation rule and 1 workflow, Startup 10 rules and 5 workflows, and Webinar 100 rules and 20 workflows.
• SMS needs Twilio, billed by Twilio.

If you need dozens of native app connections, compare the GoHighLevel integrations or the options in Systeme.io alternatives.

Our Verdict

Systeme.io's integration list is short, but it covers what most solo creators need: calendars and video calls, Google Sheets, SMS through Twilio, an optional outside email sender and a wide choice of payment gateways, all on the free plan. Zapier, webhooks with retries and logs, a broad public API and an MCP server handle almost everything else.

If your business depends on deep two-way CRM syncs, plan to use Zapier or the API, or look at a platform with more native connections. For most course creators, coaches and small online businesses, the built-in tools mean you need fewer integrations to begin with. Start with the free plan and connect one tool at a time.
