API Reference

Client Initialization

TypeScript

import Cloudflare from 'cloudflare';

const client = new Cloudflare({
  apiToken: process.env.CLOUDFLARE_API_TOKEN,
});

Python

from cloudflare import Cloudflare

client = Cloudflare(api_token=os.environ.get("CLOUDFLARE_API_TOKEN"))

# For async:
from cloudflare import AsyncCloudflare
client = AsyncCloudflare(api_token=os.environ["CLOUDFLARE_API_TOKEN"])

Go

import (
    "github.com/cloudflare/cloudflare-go/v4"
    "github.com/cloudflare/cloudflare-go/v4/option"
)

client := cloudflare.NewClient(
    option.WithAPIToken(os.Getenv("CLOUDFLARE_API_TOKEN")),
)

Authentication

API Token (Recommended)

Create token: Dashboard → My Profile → API Tokens → Create Token

export CLOUDFLARE_API_TOKEN='your-token-here'

curl "https://api.cloudflare.com/client/v4/zones" \
  --header "Authorization: Bearer $CLOUDFLARE_API_TOKEN"

Token scopes: Always use minimal permissions (zone-specific, time-limited).

API Key (Legacy)

curl "https://api.cloudflare.com/client/v4/zones" \
  --header "X-Auth-Email: user@example.com" \
  --header "X-Auth-Key: $CLOUDFLARE_API_KEY"

Not recommended: Full account access, cannot scope permissions.

Auto-Pagination

All SDKs support automatic pagination for list operations.

// TypeScript: for await...of
for await (const zone of client.zones.list()) {
  console.log(zone.id);
}

# Python: iterator protocol
for zone in client.zones.list():
    print(zone.id)

// Go: ListAutoPaging
iter := client.Zones.ListAutoPaging(ctx, cloudflare.ZoneListParams{})
for iter.Next() {
    zone := iter.Current()
    fmt.Println(zone.ID)
}

Error Handling

try {
  const zone = await client.zones.get({ zone_id: 'xxx' });
} catch (err) {
  if (err instanceof Cloudflare.NotFoundError) {
    // 404
  } else if (err instanceof Cloudflare.RateLimitError) {
    // 429 - SDK auto-retries with backoff
  } else if (err instanceof Cloudflare.APIError) {
    console.log(err.status, err.message);
  }
}

Common Error Types:

• AuthenticationError (401) - Invalid token
• PermissionDeniedError (403) - Insufficient scope
• NotFoundError (404) - Resource not found
• RateLimitError (429) - Rate limit exceeded
• InternalServerError (≥500) - Cloudflare error

Zone Management

// List zones
const zones = await client.zones.list({
  account: { id: 'account-id' },
  status: 'active',
});

// Create zone
const zone = await client.zones.create({
  account: { id: 'account-id' },
  name: 'example.com',
  type: 'full', // or 'partial'
});

// Update zone
await client.zones.edit('zone-id', {
  paused: false,
});

// Delete zone
await client.zones.delete('zone-id');

// Go: requires cloudflare.F() wrapper
zone, err := client.Zones.New(ctx, cloudflare.ZoneNewParams{
    Account: cloudflare.F(cloudflare.ZoneNewParamsAccount{
        ID: cloudflare.F("account-id"),
    }),
    Name: cloudflare.F("example.com"),
    Type: cloudflare.F(cloudflare.ZoneNewParamsTypeFull),
})

DNS Management

// Create DNS record
await client.dns.records.create({
  zone_id: 'zone-id',
  type: 'A',
  name: 'subdomain.example.com',
  content: '192.0.2.1',
  ttl: 1, // auto
  proxied: true, // Orange cloud
});

// List DNS records (with auto-pagination)
for await (const record of client.dns.records.list({
  zone_id: 'zone-id',
  type: 'A',
})) {
  console.log(record.name, record.content);
}

// Update DNS record
await client.dns.records.update({
  zone_id: 'zone-id',
  dns_record_id: 'record-id',
  type: 'A',
  name: 'subdomain.example.com',
  content: '203.0.113.1',
  proxied: true,
});

// Delete DNS record
await client.dns.records.delete({
  zone_id: 'zone-id',
  dns_record_id: 'record-id',
});

# Python example
client.dns.records.create(
    zone_id="zone-id",
    type="A",
    name="subdomain.example.com",
    content="192.0.2.1",
    ttl=1,
    proxied=True,
)
