What Systeme.io (BYOK) is for

Systeme.io (BYOK) lets an AI assistant read your own Systeme.io data through the Systeme.io API with a key you supply (public API key). Read-only: 10 tools (list_funnels, list_funnel_steps, list_email_campaigns, list_newsletters, list_contact_fields, list_courses, list_digital_products, list_price_plans, list_coupons, list_domains). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.systeme.io. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Systeme.io. Systeme.io and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

  • "What funnels do I have in Systeme.io?"
  • "What steps does funnel 123 have in Systeme.io?"
  • "Which email campaigns exist in Systeme.io?"
  • "What newsletters have I created in Systeme.io and were they sent?"
  • "Which contact fields can I use in Systeme.io?"
  • "Which courses do I offer through Systeme.io?"

What it does

  • list_funnels: List sales funnels with id, name, active flag and linked sale settings id. Cursor-paged (10 to 100 per page).
  • list_funnel_steps: List the steps (pages) of one funnel with type, position, page id, URL and linked offer id.
  • list_email_campaigns: List email campaigns (automated sequences) with id, name and sender email.
  • list_newsletters: List newsletters (broadcasts) with id, type, subject, preview text, sender and whether it was sent.
  • list_contact_fields: List the contact fields defined in the account (slug and display name).
  • list_courses: List school courses with name, description, domain, path and active flag, optionally only active ones.
  • list_digital_products: List digital products with name, origin (digital-store, funnel or Whitelabel), creation time and number of price plans and resources.
  • list_price_plans: List price plans with name, type, amount, currency and category.
  • list_coupons: List discount coupons with code, discount amount and type, currency, expiry, use limit and active flag.
  • list_domains: List the domains connected to the account with name, status and type, optionally only those usable right now.

BYOK key

You bring your own Systeme.io public API key (https://developer.systeme.io/reference/api). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.systeme.io over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

Live from the Systeme.io API (api.systeme.io) with a BYOK key; documentation: https://developer.systeme.io/reference/api. Endpoints checked against that documentation on 2026-10-16.

What it is not

Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Systeme.io. Systeme.io and its logos are trademarks of their owners and are used only to say which service the connector works with. It is read-only: it never creates, changes, sends or deletes anything in your Systeme.io account.
