Build an OnlyFans Chatbot

Want an AI or rules-based bot that answers fans automatically? The ofapis OnlyFans chatbot API gives a chatbot exactly what it needs: a signal when a new message arrives, the chat context to reason over, and a way to reply — without running a fragile browser session per creator.

The event loop

A chatbot is a webhook handler with three steps: wake, read, reply.

1. Subscribe to message.received so the bot runs only when there is something to answer — no polling.
2. Read context with the messaging API to fetch recent turns in the chat.
3. Decide and reply — pass the context to your own LLM or rules engine, then POST the answer.

# 1. Verify the webhook, then read context
curl "https://api.ofapis.com/api/public/v1/chats/123/messages?limit=10" \
  -H "Authorization: Bearer ofapis_sk_..."

# 2. Send the bot's reply
curl -X POST "https://api.ofapis.com/api/public/v1/chats/123/messages" \
  -H "Authorization: Bearer ofapis_sk_..." \
  -H "Content-Type: application/json" \
  -d '{"text":"Hey! Thanks for the message 😊"}'

Verifying the webhook

Every webhook is signed. Reject anything that fails the check before you spend a model call on it:

import hmac, hashlib

def valid(body: bytes, signature: str, secret: str) -> bool:
    digest = hmac.new(secret.encode(), body, hashlib.sha256).hexdigest()
    return hmac.compare_digest(digest, signature)

The payload carries the chatId and message text, so a fast bot can often reply straight from it and only call GET /chats/{id}/messages when it needs deeper history. Details: webhook events explained.

Bring your own brain

ofapis is the transport, not the model — you keep full control of the bot's logic and which AI it uses, with no lock-in to a built-in chatbot you cannot tune. Wire it to ChatGPT, Claude, or a no-code flow in Make or n8n. The AI assistants integration shows the common wiring.

Cost and safety

You are billed one credit per successful send or context read, and failed calls are free — so idle chats cost nothing. Because each account runs on an encrypted session with a dedicated proxy, throttle replies to a human-like pace and let a person take over high-value threads. For broadcast rather than reactive messaging, use the mass DM API instead.

FAQ

Do I need to poll for new messages?

No. Subscribe to the message.received webhook and your bot reacts in near real time, which also keeps credit usage down since idle chats never trigger a call.

Which AI can I connect?

Any. ofapis handles OnlyFans I/O and hands you the chat context; the model — ChatGPT, Claude, a local LLM, or a plain rules engine — is entirely yours.

How do I verify a webhook is genuine?

Each webhook is signed with your secret. Recompute the HMAC-SHA256 of the raw body and compare it to the signature header before acting on the event.

Can one bot serve multiple creators?

Yes. Address each creator by id under /accounts/{accountId}/chats/... and route webhook events by account, so a single bot backend covers a whole roster under one token.

What does it cost to run?

One credit per successful context read or reply; failed calls are not billed. Get a token free and test the loop in the playground or the Python quickstart.
