--- title: "Presentation Agent API | Plus AI" description: "The Plus AI Presentation Agent API — a PowerPoint API that generates PowerPoint from a prompt or your data and edits existing PPTX programmatically. A versioned REST API returning native PPTX, PDF, and thumbnail files — async, with webhooks." canonical: "https://plusai.com/features/presentation-agent-api/" --- Plus AI Presentation Agent API # Generate presentations with a single API call Send a prompt and the Presentation Agent plans, writes, and designs a finished deck — returned as native PowerPoint, PDF, and a thumbnail. Build deck generation into your product, pipeline, or workflow with the Plus AI PowerPoint API. [Sign up with Google](https://app.plusdocs.com/preinstall?idp=Google)[ Sign up with Microsoft](https://app.plusdocs.com/preinstall?idp=Microsoft) - 3 outputs PPTX, PDF, and thumbnail every run - Webhooks Or poll — your call - Edit or create Start from a prompt or your own deck ## One endpoint, many jobs - ### Generate from a prompt Describe the deck you want — say, a 10-slide product overview — and generate PowerPoint from that prompt, every slide designed into an editable .pptx. - ### Edit an existing deck Edit an existing PPTX via the API — pass a .pptx and the agent revises, extends, or restyles it in place, like refreshing last quarter's board deck with this quarter's story, on brand. - ### Fill templates with data Attach a spreadsheet and the agent writes your numbers and charts into a template — like a monthly sales review built straight from your CRM export. - ### Turn documents into slides This document-to-PowerPoint API takes a PDF, doc, or call transcript and gives a structured deck back — turn a research report into a board-ready readout in one call. - ### Translate and localize Generate or convert a deck into any language, so a single source deck ships to every region without a rebuild. - ### Refresh on a schedule Re-run the same job every week or month to keep a recurring report current — wire it into a cron and stop rebuilding it by hand. How it works ## From API key to finished deck in four steps 1. 1 ### Upload your files PUT your template and any data or source files (up to 125 MB each) and get back a fileId for each. 2. 2 ### Create a session POST a prompt to /agent/sessions — optionally with your template and attachments. You get a sessionId and polling URL right away. 3. 3 ### Poll or get a webhook Check the session until its status is DONE, or pass a callbackUrl and let the agent notify you the moment it finishes. 4. 4 ### Download the results Grab the finished pptxUrl, pdfUrl, and thumbnailUrl — ready to deliver, store, or embed. Quickstart ## A finished deck in two requests Authenticate with a bearer token, create a session, then poll for the result. 1 · Create a session bash ``` curl -X POST "https://api.plusdocs.com/r/v0/agent/sessions" \ -H "Authorization: Bearer $PLUSAI_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "prompt": "Create a 12-slide investor update from the attached metrics.", "pptxFileId": "file_abc123", "attachments": [{ "fileId": "file_def456" }], "callbackUrl": "https://example.com/hooks/plus-ai" }' ``` Response json ``` { "sessionId": "sess_9f2c1a", "pollingUrl": "https://api.plusdocs.com/r/v0/agent/sessions/sess_9f2c1a" } ``` 2 · Poll for the result bash ``` curl "https://api.plusdocs.com/r/v0/agent/sessions/sess_9f2c1a" \ -H "Authorization: Bearer $PLUSAI_API_KEY" ``` Result json ``` { "status": "DONE", "pptxUrl": "https://files.plusdocs.com/o/investor-update.pptx", "pdfUrl": "https://files.plusdocs.com/o/investor-update.pdf", "thumbnailUrl": "https://files.plusdocs.com/o/investor-update.png" } ``` [Read the full API docs](https://guide.plusai.com/apis-for-presentations/presentation-agent-api) From data to decks ## Fill templates with your data Keep a deck as a reusable template and let the agent populate it from your data — preserving layout and branding, every time. - ### Data-driven decks Generate PowerPoint from your data — attach a CSV, Excel spreadsheet, JSON, or document and the agent writes the numbers, charts, and commentary straight into your template. - ### A deck for every customer Bulk generate presentations with the API — loop over your rows, one call per customer, region, or rep, to produce a personalized deck for each from the same template. - ### Scheduled refreshes Run it on a cron to refresh a weekly report or board deck with the latest figures — hands-free. Built for developers ## Production-grade from the first request - ### Async by default Kick off a job and get a sessionId instantly. Nothing blocks while the agent works. - ### Webhooks, not waiting Pass a callbackUrl and get notified on every state change — HTTPS-only, with SSRF protection built in. - ### Bring your own content Attach spreadsheets, documents, and images so the agent grounds each deck in your real data. - ### Clean REST surface A versioned /r/v0 API with an OpenAPI 3.1 spec and conventional HTTP status codes. - ### Any language Generate or translate presentations in any language — set it per session or let the agent auto-detect. - ### Org-scoped and metered Every file and session is scoped to your organization, with clear credit accounting and typed errors. Real files, no lock-in ## Native PowerPoint out, every time Each session returns a real, editable .pptx you can open in PowerPoint or Google Slides — plus a PDF and a thumbnail. The PowerPoint API hands back native files, so the decks you generate are yours to keep. - ![Microsoft PowerPoint](https://plusai.com/images/logos/powerpoint.svg) - ![Google Slides](https://plusai.com/images/logos/google-slides.svg) ## Build it into your stack - ### Call it from anywhere It's just REST over HTTPS with a bearer token and an OpenAPI spec — call it from any language or framework. - ### Automation platforms Trigger decks from the tools you already use with Zapier, n8n, or Make — no backend required. - [ ### MCP and agents Pair this AI presentation agent with the Plus AI presentation MCP server to let your own agents generate slides as a tool. ](https://plusai.com/features/mcp) [Explore the MCP server](https://plusai.com/features/mcp) ## Developer FAQ ### How do I authenticate? Every request sends an `Authorization: Bearer $PLUSAI_API_KEY` header. API access is included on Pro and Team plans — generate a key from your Plus AI account. ### Is it synchronous or asynchronous? Asynchronous. Creating a session returns immediately with a `sessionId` and a `pollingUrl`. Poll `GET /agent/sessions/{id}` until the status is `DONE`, or pass a `callbackUrl` to receive a webhook on every state change. ### Can I edit an existing presentation? Yes. Upload a .pptx, pass its `pptxFileId` when you create the session, and edit that PowerPoint programmatically — the agent revises, extends, restyles, or translates it in place while preserving your layout and branding. ### How do I fill a template with data? Upload your template and your data export (CSV, XLSX, JSON, or a document), reference both when you create the session, and the agent writes the figures, charts, and copy into the deck. To bulk generate personalized decks, call the API once per record. ### What comes back, and how big can files be? Each finished session exposes a `pptxUrl`, a `pdfUrl`, and a `thumbnailUrl`. Files can be up to 125 MB on the way in. ### How is usage billed? Sessions draw from your plan's AI agent credits. If you run out, the API returns a typed `402 INSUFFICIENT_AGENT_CREDITS` so you can handle it gracefully. ### Is my data isolated? Every file and session is scoped to your organization. Callback URLs must be public HTTPS endpoints — localhost and private addresses are rejected to prevent SSRF.
