Cloudflare currently offers the following SDKs:

When to use cURL vs SDK

There is no definite answer on which you should use. Instead, consider your use case and determine whether cURL or an SDK is the best fit.

Use case	cURL	SDK
Quick testing within the CLI
Use within bash scripts or CI		*
Usage from within an existing application or framework
More complex usage where you need to chain together outputs

* It is possible, although not straight forward, to use the SDKs within bash scripts or CI environments with additional runtime dependencies and setup.

Example

The following are examples of how you would query all of the Cloudflare zones you have access to.

With cURL:

curl "https://api.cloudflare.com/client/v4/zones" \
--header "Authorization: Bearer <API_TOKEN>"

With the TypeScript SDK:

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

const zones = await client.zones.list();

console.log(zones);
