Bespot Gatekeeper Web SDK

Web SDK for Bespot Gatekeeper, a fraud prevention and location integrity platform for web applications.

Use this SDK to run real-time fraud checks in browser sessions and receive policy results for high-risk actions such as signup, login, checkout, reward redemption, wallet actions, account changes, or location-restricted access.

Gatekeeper helps detect and evaluate bot traffic, AI agents, location spoofing, VPN/proxy use, suspicious browser or device signals, multi-accounting, and abuse patterns such as bonus, promo, or reward fraud.

Installation

SDK bundles are distributed via npm and GitHub Releases (safe-sdk.esm.min.js, safe-sdk.umd.min.js). Each release includes both ESM and UMD builds — download and host directly; no extraction step required.

npm (recommended)

Requires Node.js on your development machine to run npm install. The SDK itself runs in the browser — Node is not needed at runtime.

npm install @bespot/gatekeeper-web-sdk

import SafeSDK from '@bespot/gatekeeper-web-sdk'

CDN / script tag (no build step)

No Node.js required. Download safe-sdk.esm.min.js or safe-sdk.umd.min.js from the Releases page and host the files on your CDN or static origin.

Quick start

• Account — sign in at gatekeeper.bespot.com and collect your credentials
• Install — npm install @bespot/gatekeeper-web-sdk or download from Releases
• Configure — four runtime fields: baseUrl, apiKey, applicationId, applicationVersion (runtime configuration)
• Authenticate — obtain a JWT from your backend (authentication)
• Integrate — await sdk.initialize(jwt) then await sdk.check() (integration sequence)

const sdk = new SafeSDK({
  baseUrl: 'bespot-gatekeeper-base-url', // e.g. 'https://gatekeeper.bespotcompany.com'
  apiKey: 'your-api-key', // e.g. '13CTrcYiya9NNnRyd3jXA21CULPPDSqM90sdFnGs'
  applicationId: 'your-app-id', // e.g. 'mywebapp.mycompany.com'
  applicationVersion: 'your-app-version', // e.g. '2.4.1'
})

await sdk.initialize(jwt)

const result = await sdk.check()
if (result instanceof Error) {
  console.error('Check failed:', result.name)
} else {
  console.log('Check passed:', result)
}
