Language SDKs
JavaScript and TypeScript
Send published Sendery templates from JavaScript and TypeScript.
npm install @sendery/sdkRequirements
Node.js 22.12+. The package uses ES module imports and includes TypeScript types.
Set up
Publish a welcome template with name and action_url variables, and create a project API key. Store it as SENDERY_API_KEY on your server. Use the SDK only on the server.
export SENDERY_API_KEY="your_project_api_key"Send an email
The response contains the accepted email’s id and status.
import { Sendery } from '@sendery/sdk';
const apiKey = process.env.SENDERY_API_KEY;
if (!apiKey) throw new Error('Set SENDERY_API_KEY on your server.');
const sendery = new Sendery(apiKey);
const receipt = await sendery.send({
to: '[email protected]',
template: 'welcome',
data: { name: 'Alex', action_url: 'https://example.com/start' },
});
console.log(receipt.id);Retrieve an email
Use the returned ID to check delivery status.
const message = await sendery.get(receipt.id);
console.log(message.status);Retry a send
Use a key such as welcome-123 for one email, and keep the payload unchanged on retries. retry(3) allows up to three additional attempts for temporary failures; send() alone makes one attempt.
const email = sendery.prepare({
to: '[email protected]',
template: 'welcome',
data: { name: 'Alex', action_url: 'https://example.com/start' },
}, 'welcome-123');
const receipt = await email.retry(3).send();Handle errors
Catch the SDK exception to inspect the status and code. Retry delays are in seconds. The example uses the prepared email from the retry example above.
import { SenderyError } from '@sendery/sdk';
try {
const receipt = await email.retry(3).send();
console.log(receipt.id);
} catch (error) {
if (error instanceof SenderyError) {
console.error(error.status, error.code, error.errors);
// error.retryAfter is a delay in seconds, when provided.
}
throw error;
}
