How to Combine Ads With a Subscription in n8n
This guide shows how to combine ads with a subscription in a n8n app, the goal being to run ads on the free tier and a paid ad-free tier together. It builds on the Monetzly server SDK, so the approach is specific to how n8n produces and streams responses.
Overview
Ads and subscriptions are not mutually exclusive for a n8n app. A common setup runs Monetzly ads on the free tier and offers a paid, ad-free tier for power users — capturing revenue from casual and committed users alike.
Implementation is a branch on the response path: enable injection for free-tier sessions and skip it for paying users, based on your own n8n app's user state.
n8n apps are usually built for automated AI workflows, chatbot backends, and agent orchestration, so combine ads with a subscription typically comes up while a user is mid-conversation, the moment where monetization has to be additive rather than disruptive.
How this works on n8n
n8n runs on Node, so a Code node (or a small custom node) can import @monetzly/server-sdk and wrap the token output of an upstream LLM node. Because n8n items are usually discrete rather than a live token stream, confirm whether you inject over a buffered response or a true stream for your workflow.
Because Monetzly's inject() accepts any async token stream, the n8n side of this task is just mapping your output to it, no rewrite of your n8n model call.
Steps
- Determine the user's tier from your n8n app's auth/session state.
- Run ad injection for free-tier sessions.
- Skip injection (return the plain stream) for paying, ad-free users.
