OnlyFans Automation API — Mass DMs, Scheduling & Webhooks for Agencies

DEFINITION

What is OnlyFans automation?

OnlyFans automation is the practice of using software to perform repetitive creator-account work — sending welcome DMs, blasting PPV campaigns, scheduling feed posts, tagging fans by spend, replying to tips, and exporting earnings — without a human having to log in and click through the OnlyFans web app for each action. In an agency context, it is what makes managing 50, 100, or 500 accounts financially viable: one chatter operates a roster of creators while the automation layer handles the predictable work in the background.

In practice, OnlyFans automation runs through an OnlyFans API that wraps the same endpoints the official site uses, signed with realistic browser headers and routed through per-account proxies so the platform sees ordinary, human-paced traffic. On top of that API sits a rules engine that listens for events (a new subscriber, a tip, a renewal, a refund) and dispatches actions (send a DM, fire a webhook, post to Discord, write a row to your CRM). That is what an OnlyFans automation API delivers — and it is what this page covers in detail.

Done well, automation is invisible to the fan and transformative for the operator. Done badly, it gets accounts banned. The difference is engineering. The Only API was built by agency operators specifically to make the first outcome the default and the second outcome impossible-by-default.

Example: create an automation

curl -X POST https://api.theonlyapi.com/v1/automations \
  -H "X-API-Key: $OF_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Welcome new VIPs",
    "trigger": "subscriber.created",
    "conditions": [
      { "field": "payload.price", "op": "gt", "value": 25 }
    ],
    "action": {
      "type": "of_dm.send",
      "params": {
        "of_user_id": "{account.of_user_id}",
        "to_user_id": "{payload.fan_id}",
        "text": "Hey {payload.fan_name} — thanks for subscribing! Reply BONUS for a free PPV.",
        "media_ids": [],
        "price": 0
      }
    }
  }'

That single POST creates a persisted rule. Every time a fan subscribes for more than $25, they receive a templated welcome DM within seconds.

SAFETY & RATE LIMITS

Responsible automation, by default

OnlyFans is a real platform with real rate limits and real terms of service. Any provider promising a "ban-proof" or "undetectable" automation is selling a fantasy. What an honest OnlyFans automation API can deliver is engineering that minimises risk: realistic-pace polling, browser-grade header signing, isolated per-account sessions, optional residential proxies, and exponential back-off on every retry.

The Only API polls each connected account on a schedule that mirrors normal human use — typically every 30 to 90 seconds for active accounts, longer for idle ones. We sign requests with the same Chrome 136 fingerprint a logged-in browser uses, and every account is sandboxed in its own multi-tenant session file. Across 500+ agencies running on the platform we have not seen a single account banned as a direct consequence of using the API. We will not promise that record holds forever — what we will promise is that we treat the upstream platform with respect, and we ship fixes within hours when something changes.

Mass DM sends are throttled per-account. Scheduled posts queue with jitter. Webhook deliveries retry on a [5s, 30s, 5m, 30m, 2h] back-off and auto-deactivate after sustained failure. If you want to push beyond the defaults, you can — but the defaults are deliberately conservative because the cost of a banned creator account is always higher than the value of an extra DM per minute.
