Fansly API Integration Guide: Setup, Webhooks & Endpoints

By Anna

Question answered

How do I integrate the Fansly API into my application?

TL;DR

  • Webhooks cost 1 credit per 100 events and fire on every message, sale, renewal, subscription, tip, and chat event with HMAC-SHA256 signing.
  • 200+ live endpoints cover accounts, fans, chats, earnings, posts, media, stories, statistics, and tracking links.
  • Team management, full request logs, dashboard analytics, and a public status page give production-grade visibility from day one.
Real-time webhooks, full logs, and a public status page mean teams ship Fansly integrations instead of debugging them.

If you're building a Fansly tool — CRM, automation, dashboard, or full agency platform — the Fansly API gives you authenticated access to 200+ live endpoints with real-time webhooks. This guide walks through everything you need to ship a production integration: account setup, webhook handling, credit budgeting, team access, and operational monitoring.

What you need before integrating the Fansly API

Three things are required for any Fansly API integration:

  1. A Fansly API account — sign up free at fansly-api.com/register. The free tier includes 10 credits for testing any endpoint.
  2. An API key — generated in the dashboard, scoped per-team-member, and rotated on demand.
  3. A Fansly creator account to connect — required for authenticated calls that read or write creator-side data.

Once you have these three, you're ready to make your first call.

How Fansly webhooks work

Webhooks are the production-grade alternative to polling. Every event in Fansly — new message, sale, renewal, subscription, tip, chat reaction — fires a webhook to the endpoint you register in the dashboard.

Each webhook delivery includes:

  • HMAC-SHA256 signature in the X-Fansly-Signature header
  • Event type (message.received, sale.completed, subscription.renewed, subscription.expired, tip.received, chat.reaction, and more)
  • Payload with the full event data
  • Idempotency key to deduplicate retries

Verify the signature before doing anything with the payload:

import { createHmac } from 'crypto'
 
function verifyWebhook(body, signature, secret) {
  const expected = createHmac('sha256', secret)
    .update(body)
    .digest('hex')
  return signature === expected
}

Then deduplicate on the idempotency key to make retries safe:

const seen = new Set()
 
function handleWebhook(event) {
  if (seen.has(event.idempotencyKey)) return
  seen.add(event.idempotencyKey)
  // process the event
}

Webhook pricing is 1 credit per 100 events delivered. Failed deliveries retry with exponential backoff and surface in the Webhook Logs page in the dashboard.

Common webhook patterns

  • Chatbot sync — subscribe to message.received, run AI inference, send reply via the messaging endpoint
  • Whale alerts — subscribe to tip.received, fire a Slack/Telegram alert when amount exceeds a threshold
  • CRM updates — subscribe to subscription.renewed and subscription.expired, sync fan status to your CRM
  • Revenue dashboards — subscribe to sale.completed, write to your warehouse for real-time reporting

Pricing and credits explained

Credits are the unit of usage across the Fansly API. Each call, webhook, or media download consumes a known number of credits.

  • Free tier: 10 credits to test any endpoint
  • Basic: $69/month, 20,000 credits + 1,000 RPM, 1 account
  • Pro: $299/month, 50,000 credits + 10,000 per account + 5,000 RPM, 5 accounts
  • Enterprise: 100+ accounts with custom development, per-account pricing as low as $10

Webhook events are priced at 1 credit per 100 events. The Credits table on the Usage page breaks down consumption by feature — so you always know where your credits are going.
