Features

• Generate Presentation (Async): Kick off a background job to create PPTX or PDF
• Check Presentation Status: Poll a task by ID until it’s complete
• Upload File: Upload binary files and reference them during generation

Installation

Install in n8n (Community nodes)

1. In n8n, go to Settings → Community Nodes → Install.
2. Search for or enter the package name: n8n-nodes-Presenton.
3. Confirm installation and restart n8n if prompted.

Self-hosted filesystem install

If you mount community nodes from disk, add this package to your custom nodes directory and install:

npm install n8n-nodes-Presenton

Minimum Node.js version: 20

Credentials

Create credentials of type Presenton API:

• API Key: Your Presenton API key
• Base API URL (optional): Override the default https://api.presenton.ai for staging or self-hosted deployments

The node adds the Authorization: Bearer <apiKey> header automatically.

Node operations

Generate Presentation (Async)

Starts a background job: POST /api/v1/ppt/presentation/generate/async

• content: Main content to generate from
• slides_markdown: Optional list of slide markdown strings
• instructions: Additional guidance for the generator
• tone: default | professional | educational | funny | sale_pitch | causal
• verbosity: standard | concise | text-heavy
• web_search: Allow web search during generation (boolean)
• image_type: stock | ai-generated
• theme: Theme name (string)
• noOfSlides: Number of slides (number)
• language: e.g. English
• template: e.g. general
• include_table_of_contents: boolean
• include_title_slide: boolean
• files: A file ID returned by the Upload File operation (string[])
• export_as: pptx | pdf

The node cleans empty values before sending. Response typically includes a task identifier you can pass to Check Presentation Status.

Check Presentation Status

Checks a task: GET /api/v1/ppt/presentation/status/{taskId}

• taskId: The ID returned by Generate Presentation (Async)

Returns the current status. When complete, the API usually includes result metadata (such as download links) defined by Presenton.

Upload File

Uploads a binary file: POST /api/v1/ppt/files/upload

• binaryPropertyName: Name of the binary property on the incoming item (default: data)

Returns a file ID you can set in the files field of the Generate Presentation (Async) operation.

Typical workflow examples

Generate a presentation from text

1. Set operation to “Generate Presentation (Async)”.
2. Fill in content, choose export_as (e.g. pptx), adjust options (tone, verbosity, slides, etc.).
3. Use “Check Presentation Status” with the returned taskId until status is complete.

Upload then generate

1. Add a node with operation “Upload File” and set binaryPropertyName to the property holding your file.
2. From its response, read the returned file id.
3. Pass that id into the files field of “Generate Presentation (Async)”, then check status as above.

Error handling

• The node validates required parameters and throws meaningful errors (e.g., invalid slide count, missing task ID, or missing binary data).
• If you enable “Continue On Fail”, errors are returned in the item’s JSON so your workflow can handle them.

Development

npm i
npm run dev   # TypeScript watch
# or
