SDK overview

Biqli provides separate SDKs for public browser tracking and trusted server tracking.

Browser SDK

Use @biqli/analytics with a publishable key in HTML or React.

TypeScript SDK

Use @biqli/sdk on Node.js 18 or newer with a secret API key.

PHP SDK

Use biqli/sdk on PHP 8.1 or newer with a secret API key.

Choose by runtime

Runtime	Package	Credential
Browser JavaScript	`@biqli/analytics`	`biqli_pk_...` publishable key
React client component	`@biqli/analytics/react`	`biqli_pk_...` publishable key
Plain script tag	`https://biq.li/sdk/dist/auto.global.js`	`biqli_pk_...` publishable key
Node.js, Next.js server, React Router server	`@biqli/sdk`	`biqli_...` secret API key
PHP or Laravel	`biqli/sdk`	`biqli_...` secret API key
Other server languages	REST API	`biqli_...` secret API key

Never substitute one credential type for the other. The server SDKs reject browser use, and the browser SDK rejects secret API keys.

SDKs versus endpoint reference

SDKs provide typed inputs, request IDs, idempotency handling, structured errors, and bounded retries. Endpoint pages define the wire-level JSON contract and remain the source of truth for field validation.

Follow Developer Docs for tutorials and architecture.
Use Track a lead and Track a sale for complete server request fields.
Use API authentication for permissions and key lifecycle.
