# Presenton API Introduction

> Build, edit, and export slide decks programmatically with reusable templates and AI

Presenton API lets you create, edit, and export AI presentations directly from your applications, services, workflows, or scripts using a simple REST interface. It combines AI with a template-driven approach, so every deck is fast to produce, consistently structured, and on brand. Bring your own custom templates and themes, or use built-in templates. Then guide structure, tone, and verbosity with clear prompting instructions to fit any audience or domain.

Start new decks from scratch or reuse and refine existing presentations, with fine-grained control over slides, sections, text, images, and more. The result is a reliable, scalable way to automate presentation creation across teams and systems.

<Warning>
  If you're using open-source, use v1 APIs. v3 APIs are not yet available on open-source.

## Features

### Template-based approach

Presentations are created from templates to ensure visual consistency.

* Use built-in templates provided by Presenton
* Create your own templates by importing an existing PDF or PPTX
* Apply templates repeatedly while swapping content, icons, and images

### Core inputs

There are two main inputs that shape the output:

* **instructions**: Steer structure and style. Use this to specify outline guidance, section ordering and other
* **content**: Supply the material to include—facts, bullet points, talking points, or a prompt describing what the deck should cover.

### Editing and reuse

* Edit specific parts of a generated presentation (individual slides, sections, text blocks, images) through the API.
* Use an existing presentation as a base, adjust selected elements, and generate a new version without starting from scratch.

### Web search

Enable web search to let Presenton gather context before generation. This can improve the stability and freshness of the content, especially for data-sensitive or time-bound topics.

## How generation works internally

Presenton uses a multi-step pipeline:

* **Outline generation**
* **Structure and slide layout selection**
* **Content(text, images and icons) generation for selected slide layouts**

This process typically takes up to 1–2 minutes, depending on slide count and complexity.
