# cURL

Send emails using cURL with Mailtrap through SMTP integration or API endpoints with code samples and configuration options.

## Overview

Mailtrap can be integrated with cURL for email sending via SMTP or email API.

Before we start, you'll need to:

* [Verify your sending domain](/email-api-smtp/setup/sending-domain.md)
* [Create and save an API key](/email-api-smtp/setup/api-tokens.md)

### Send emails using cURL and Mailtrap

#### SMTP integration

To integrate Mailtrap via SMTP, go to the **Integration** tab and copy/paste either the credentials or the pre-made code snippets into your configuration.

You can get more information on SMTP integration [here](/email-api-smtp/setup/smtp-integration.md).

#### API integration

To integrate Mailtrap and send emails via cURL, use the configuration available among **Code samples** under the API section.

Once you copy the script, make sure to insert your Mailtrap API token in the `Authorization` field as `Bearer` and enter your and your recipient's emails in the `--mail-from` and `--mail-rcpt` fields.

## Next steps

After setting up cURL integration, you can send test emails and monitor delivery through your Mailtrap dashboard to ensure proper configuration.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.mailtrap.io/guides/integrations/curl.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
