Building an OnlyFans Growth Stack: n8n, Baserow and the OnlyFans API

The most successful OnlyFans agencies do not run their operations from spreadsheets. They build integrated growth stacks — automated systems that connect their OnlyFans data to databases, dashboards, and workflow engines. With the OnlyFans API now processing over 300 million requests and serving 1,100+ companies, the infrastructure exists to build sophisticated agency operations without writing complex code.

This guide walks through building a complete growth stack using three tools: n8n for automation, Baserow for database management, and The Only API for OnlyFans data.

What Is a Growth Stack for OnlyFans Agencies?

A growth stack is the collection of interconnected tools that power your agency's operations. Instead of manually checking earnings, sending messages, and compiling reports, a growth stack automates these workflows and centralizes data.

A well-designed OnlyFans growth stack handles:

• Data collection: Automatically pulling earnings, subscriber counts, message stats, and content performance from every managed account

• Data storage: Centralizing all data in a structured database for analysis and reporting

• Automation: Triggering actions based on data events (revenue milestones, subscriber churn signals, content scheduling)

• Reporting: Generating dashboards and reports for internal use and creator-facing updates

The Architecture: n8n + Baserow + The Only API

Here is how the three components fit together:

The Only API (Data Layer)

• Connects to OnlyFans accounts via API

• Provides 200+ endpoints for earnings, subscribers, messaging, content, and more

• Serves as the single source of truth for all OnlyFans data

Baserow (Database Layer)

• Open-source alternative to Airtable

• Stores structured data: creator profiles, earnings history, subscriber metrics, campaign results

• Provides a visual interface for browsing and editing data

• Supports API access for automated reads and writes

n8n (Automation Layer)

• Open-source workflow automation platform

• Connects The Only API to Baserow (and any other tool)

• Triggers workflows based on schedules, webhooks, or data conditions

• Has native n8n nodes for common integrations

Step-by-Step: Connect API, Pipe Data to Baserow, Trigger Workflows

Step 1: Set Up The Only API

Sign up at theonlyapi.com and connect your first OnlyFans account. You will receive an API key that provides access to all 200+ endpoints.

Step 2: Set Up Baserow Tables

Create the following tables in Baserow:

Creators Table:

• Creator Name (text)

• OnlyFans Username (text)

• Account ID (text)

• Status (dropdown: active, paused, offboarding)

• Start Date (date)

Daily Earnings Table:

• Creator (link to Creators)

• Date (date)

• Subscriptions Revenue (number)

• Tips Revenue (number)

• PPV Revenue (number)

• Total Revenue (number)

• New Subscribers (number)

• Churned Subscribers (number)

Campaign Results Table:

• Creator (link to Creators)

• Campaign Name (text)

• Send Date (date)

• Messages Sent (number)

• Opens (number)

• Purchases (number)

• Revenue Generated (number)

Step 3: Build n8n Workflows

Workflow 1: Daily Earnings Sync

1. Schedule trigger: runs daily at 2:00 AM

2. For each creator in Baserow "Creators" table:

   • Call The Only API earnings endpoint for yesterday's date

   • Parse subscription, tip, and PPV revenue

   • Write a new row to "Daily Earnings" table

3. Send Slack notification with daily summary

Workflow 2: Subscriber Churn Alert

1. Schedule trigger: runs every 6 hours

2. For each creator:

   • Call The Only API subscriber endpoint

   • Compare current count to previous count in Baserow

   • If subscriber count dropped by more than 5% in 24 hours, trigger alert

3. Send alert to team with creator name and churn percentage

Workflow 3: Content Schedule Enforcement

1. Schedule trigger: runs every hour

2. Check Baserow "Content Calendar" table for posts due in the next hour

3. For each pending post:

   • Call The Only API content posting endpoint

   • Update Baserow status to "posted"

   • Log posting time and confirmation

Example Workflows: Revenue Alerts, Churn Detection, Content Scheduling

Beyond the basics, here are advanced workflows that top agencies run:

Revenue milestone notifications. When a creator crosses a revenue threshold ($10K, $50K, $100K), automatically send a congratulations message and update their tier in your CRM.

Fan re-engagement campaigns. Identify subscribers who have not engaged in 7+ days using API data, then trigger an automated re-engagement mass message with special PPV content.

Automated weekly reports. Every Monday morning, generate a formatted report for each creator showing their weekly performance: revenue, subscriber growth, top-performing content, and campaign results.

New subscriber welcome flows. When a new subscriber joins, trigger a welcome DM sequence over 3 days: Day 1 welcome, Day 2 content teaser, Day 3 PPV offer.

Why This Stack Beats Spreadsheets
