Documentation

Hello, developer.

Everything your team needs to build on CD4CD: a REST API, webhooks, multi-language SDKs, and real examples that don't use fake keys.

REST API

Every endpoint, curl examples, JSON responses, rate limits.

Webhooks

link.created, link.clicked, qr.scanned events with full payloads.

SDKs

Node, PHP, Python, Go — install + auth + first request.

Guides

ZATCA, A/B testing, Salla integration, building a pro Bio page.

Status

Live uptime, 90-day history, past incidents.

Blog

Technical updates, big-change rationale, use-cases.

Quickstart — your first link in 60 seconds

  1. 01
    Get an API key

    From /dashboard/api → "New key".

  2. 02
    POST a request

    To https://api.cd4cd.com/v1/links with longUrl.

  3. 03
    Save shortUrl

    Use it in campaigns or your app.

$ curl -X POST https://api.cd4cd.com/v1/links \
  -H "Authorization: Bearer cd_live_xxx" \
  -H "Content-Type: application/json" \
  -d '{"longUrl":"https://example.com/very/long/path"}'

{ "shortCode": "abc123",
  "shortUrl":  "https://cd4cd.com/abc123",
  "createdAt": "2026-05-13T05:42:00Z" }
