Our API allows customers to access all the key parts of the Rebel platform. You can access templates, create and edit campaigns, get HTML for sending and even send emails directly. For a more in-depth understanding of our API basics, check out our `Getting Started` guide.

Our request structure is straightforward to develop against. While it’s a bit too complicated to cover in a paragraph, we do have a full write up on our structure.

If you are a marketer looking to send the same email to a large batch of people, you should look at our Rebel Mail offering. But if you are looking to send individualized messages to each of your recipients or you want to automate the creation of interactive emails, then our API is the tool for you.
