Connect your Meta Pixel to OnlyFans API Smart Links
Send configurable Smart Link click, subscription, purchase, and reply events to Meta through the server-side Conversions API.
What is a Meta Pixel?
A Meta Pixel (now called a dataset in Events Manager) is Meta's conversion tracking tool for Facebook and Instagram ads. It tells Meta when someone takes an action, such as subscribing or purchasing, after clicking your ad.
Why connect it to Smart Links? OnlyFans doesn't support Meta's pixel natively, and there's no way to install tracking code on OnlyFans pages. Smart Links can send the events you configure to Meta's Conversions API without installing JavaScript on OnlyFans.
What you'll need
- An active OnlyFans API account with Smart Links enabled
- A Meta Business account with access to Events Manager
- Your Meta Pixel ID and a Conversions API access token (we'll get both below)
Why this matters for Meta
Meta cannot observe subscriptions, tips, PPV purchases, or replies on OnlyFans through browser JavaScript. Smart Links sends configured events from OnlyFansAPI's servers instead. Delivery can still fail because of invalid credentials, rejected payloads, or platform availability; inspect the pixel's event logs in OnlyFansAPI.
This guide is the Meta-specific setup. For how Smart Links work under the hood, including attribution rules, the conversion window, lifetime revenue attribution, and postback variables, see the Smart Links guide.
Step-by-step setup
Find your Meta Pixel ID
In Meta Events Manager, open the All Tools menu and select Events Manager.

In Events Manager, open Data Sets and select your dataset. Your Pixel ID (also called the Dataset ID) is shown next to the dataset name. Copy it, then open the Settings tab to grab the access token next.

If you manage multiple businesses or clients, make sure you've selected the correct Business and Pixel/Dataset before copying the ID and generating the token below.
Generate a Conversions API access token
Meta's server-side Conversions API needs an access token in addition to the Pixel ID. This is how Smart Links authenticate when sending events to Meta.
With your dataset selected, open the Settings tab, scroll to the Conversions API section, and click Generate access token.

Copy the access token and keep it safe, and treat it like a password. Make sure the correct Pixel/Dataset is selected before generating, or the token won't match the Pixel ID you copied.
Create or open a Smart Link
Log into your OnlyFans API Dashboard, open Smart Links → Links, and click Create Smart Link. To use an existing link, open its action menu and click Edit.
- Account: the OnlyFans account you're running ads for
- Smart Link Name: something descriptive, e.g. your Meta campaign name
- Offer Type: Free Trial or Tracking Link
Add your Meta pixel
Open Smart Links → Tracking Pixels and click Add Pixel. In the Add Tracking Pixel dialog:
- Set Platform to Meta Ads
- Paste your Pixel ID from Step 1
- Paste your Conversions API access token from Step 2 into the Access Token field
- Choose All traffic sources, or create matching rules and scope the pixel to specific traffic sources
- Review the Event Configuration (see Events sent to Meta below)
- Click Create
Attach the pixel to your Smart Link
Open Smart Links → Links, edit the Smart Link, and select the pixel in Tracking Pixels. You can attach more than one pixel to a link.
Send a test event
In Meta Events Manager, open your dataset's Test Events tab and copy the test event code.
Back in the OnlyFans API Dashboard, open the Send Test Event dialog on your pixel, pick an Event, paste the Test Event Code, and send it. Then check the Test Events tab in Meta, where your event should appear within a few minutes.

Events sent with a test event code don't affect your live data. They're only for verifying the connection. The Test Event Code is required for Meta.
Use the Smart Link in your Meta ad
In Meta Ads Manager, set your ad's Website URL to your Smart Link:
https://trk.of-traffic.com/go/YOUR_SMART_LINK_ID?ecid={{ad.id}}Replace YOUR_SMART_LINK_ID with the ID from your Smart Links dashboard. Meta automatically appends its click ID (fbclid) to the destination URL, and Smart Links reads it straight from the fbclid parameter to attribute conversions to your Meta Pixel. There's no macro to add for pixel tracking.
The optional ?ecid={{ad.id}} parameter passes Meta's Ad ID as your external click ID so you can match conversions back to specific ads in your own reporting. Swap in {{campaign.id}}, {{adset.id}}, or any other Meta dynamic parameter for the level of granularity you need.
Verify conversions are flowing
Once your ads are live:
- Smart Links dashboard: you should see clicks, subscribers, and revenue
- Meta Events Manager: conversion events appearing on your pixel (check the Overview and Test Events tabs)
- Meta Ads Manager: the campaign's Results column filling in with tracked conversions
Events sent to Meta
Smart Links can send the following events to your Meta Pixel. Each one maps to a Meta event in the Event Configuration section when you add the pixel. These are the defaults, and every event is configurable (map it to any Meta standard event, a custom event, or turn it off).
| Smart Link event | When it fires | Meta event (default) |
|---|---|---|
| Click | Fan clicks the Smart Link and is redirected to OnlyFans | ViewContent |
| New Subscriber | Fan subscribes through the Smart Link | Subscribe |
| First Purchase | First transaction other than the initial new-subscription payment. A rebill can be first. | Purchase |
| Repeat Purchase | Other transactions, including the initial new-subscription payment and transactions after First Purchase | Purchase |
| Message Received from Fan | Fan sends a message after converting | Not sent by default |
| Fan Sent 1st Message | Fan reaches their 1st inbound message | Contact |
| Fan Sent 3+ Messages | Fan reaches their 3rd inbound message | Lead |
For subscriber and purchase events, Smart Links also sends the conversion value and currency when available.
Custom event mapping
The Event Configuration lets you map each Smart Link event to any Meta standard event, a custom event, or turn it off—so if the defaults don't match how you've set up your pixel, remap them.
For example, to send CompleteRegistration instead of Subscribe: open the pixel's Event Configuration, find New Subscriber, and set its Meta event to CompleteRegistration. Pick a custom event if you'd rather send an event name of your own.
Data sent to Meta
Smart Links sends fbc derived from fbclid, fbp, a hashed external_id derived from ecid, the visitor's IP address and user agent, and hashed country, city, state, and postal code when available. It does not send the fan's email, phone number, or name to Meta. Meta calculates match quality from the data it receives; inspect Events Manager for the result on your dataset.
Troubleshooting
| Problem | Fix |
|---|---|
| No events showing in Meta | Double-check you pasted both the Pixel ID and the Conversions API access token, and that the token was generated for the same Pixel/Dataset as the ID. |
| Test event never appears | A Test Event Code is required for Meta. Copy it from your dataset's Test Events tab and paste it into the Send Test Event dialog. Allow a few minutes. |
| Events arrive but the campaign isn't optimizing | Set your ad set's optimization goal to the matching conversion event (e.g. Purchase or Subscribe). |
| Meta shows the pixel as inactive | Send a test event from Smart Links → Tracking Pixels, then check the dataset's Overview tab. |
| Which domain do I whitelist for the Conversions API? | None. OnlyFansAPI sends events directly to Meta. Visitors still use your landing-page domain, if any, and trk.of-traffic.com for the Smart Link redirect. |
| Conversions underreported from Instagram traffic | Confirm every landing-page hop forwards fbclid, ecid, and UTM parameters. Built-in Smart Links pre-landers forward these values; see Pre-landers. |
