# Introduction

> Send letters, telegrams, e-Carta, registered e-mails and WhatsApp messages through one API.

The **Escrybe API** lets you dispatch physical and digital correspondence
programmatically through Brazilian Correios and WhatsApp, with legal
traceability and certified timestamps.

## How it works

<Steps>
  <Step title="Get your token">
    Grab your `securityToken` from the panel under **My Settings → API access**.
  </Step>

  <Step title="Authenticate">
    Send the token with every request — see [Authentication](/en/authentication).
  </Step>

  <Step title="Create an order">
    Call the relevant `post` endpoint. Orders are charged against your credits
    (or invoiced).
  </Step>

  <Step title="Track it">
    Poll the matching `get` endpoint for status and tracking updates.
  </Step>
</Steps>

<Note>
  Many request and response field names are in Portuguese because they map
  directly to the underlying Correios and platform data model.
