# Introduction

> Run every campaign, lead, mailbox and inbox action over HTTP.

Sales Sequencer sends cold email sequences from your own Google, Outlook and SMTP mailboxes, warms them up and sorts every reply. The API gives you the same actions as the app: create and launch campaigns, add leads, manage mailboxes, read and answer replies, and run your team and workspaces.

```bash theme={null}
curl "https://api.salessequencer.com/api/v1/campaigns/list" \
  -H "X-API-Key: YOUR_API_KEY"
```

Each call runs **as the person who created the key**, with **that person's role**, in **the key's workspace**. So the API can never do more than that person could do in the app.
