SDK Features

All SDKs provide:

• Type Safety - Full type definitions for all requests and responses
• Native HTTP - Uses each platform's native HTTP client (fetch, URLSession, OkHttp, HttpClient, Faraday)
• Auto-Generated - Always in sync with the latest API specification
• Zero Config - Just provide your API key and start sending

Quick Comparison

Node.js / TypeScript

import { EmailsApi, Configuration } from '@zyphr-dev/node-sdk';

const config = new Configuration({
  apiKey: process.env.ZYPHR_API_KEY,
});

const emails = new EmailsApi(config);
await emails.sendEmail({
  sendEmailRequest: {
    to: 'user@example.com',
    subject: 'Hello',
    html: '<p>Hi!</p>',
  },
});

Swift (iOS)

import ZyphrSDK

let config = Configuration(apiKey: "zy_live_xxx")
let emails = EmailsAPI(configuration: config)

try await emails.sendEmail(
    sendEmailRequest: SendEmailRequest(
        to: "user@example.com",
        subject: "Hello",
        html: "<p>Hi!</p>"
    )
)

Kotlin (Android)

import dev.zyphr.sdk.api.EmailsApi
import dev.zyphr.sdk.infrastructure.ApiClient

val client = ApiClient(apiKey = "zy_live_xxx")
val emails = EmailsApi(client)

emails.sendEmail(
    SendEmailRequest(
        to = "user@example.com",
        subject = "Hello",
        html = "<p>Hi!</p>"
    )
)

React (Inbox Component)

import { ZyphrInbox, ZyphrProvider } from '@zyphr/inbox-react';

function App() {
  return (
    <ZyphrProvider publicKey="za_pub_xxx" subscriberId="user_123">
      <ZyphrInbox />
    </ZyphrProvider>
  );
}

REST API

Don't see your language? The REST API is simple to use directly:

curl -X POST https://api.zyphr.dev/v1/emails \
  -H "X-API-Key: zy_live_xxx" \
  -H "Content-Type: application/json" \
  -d '{"to": "user@example.com", "subject": "Hello", "html": "<p>Hi!</p>"}'
