Build with Fabric

SMS + email / direct + managed

Fabric gives your server one typed SDK for direct SMS, direct email, and versioned managed messages. Start with a test key, send through the virtual delivery path, and inspect the result before you configure live routes.

Send your first message

Understand the platform

Choose how to send

Direct SMS

Put the final body and sender in the request. Send one message or a batch of up to 100. Open the SMS guide.

Direct email

Send text or HTML from a verified domain, then retrieve and list the resulting messages. Open the email guide.

Managed messages

Publish versioned SMS or email content and send it from your application by a stable key. Open message definitions.

Start in sandbox

1. Create an application. It owns the keys, environments, messages, webhooks, and activity for one integration.
2. Create a test key. Store the sk_test_ key in your server-side secret manager as FABRIC_API_KEY.
3. Send from your server. Use direct content or address a published managed message by key.
4. Follow the outcome. Read the delivery or process its signed webhook event.

Server-side only

Fabric secret keys must never be exposed in browser code, mobile apps, public repositories, logs, or client-visible environment variables. Call Fabric from a trusted server.
