Automate Marketing Report Presentations: Deck to Video API (2026)

To automate marketing report presentations, run a Monday cron that pulls campaign metrics, asks an LLM for an 8-slide narrative, and calls three 2Slides endpoints: create-pdf-slides for an image-designed 16:9 recap deck, generate-narration in multi mode for a two-voice track, and download-slides-pages-voices for per-page PNG and WAV files that ffmpeg stitches into an MP4. An 8-page 2K deck costs 810 credits (about $2), narration adds 1,680 credits (about $4.20), so a narrated weekly recap lands near $6 per client. Built for marketing ops, growth engineers, and agencies.

Key takeaways

• One scheduled job replaces the Monday ritual: metrics export, 8-slide recap deck, two-speaker voiceover, and a 1920×1080 MP4.
• Three 2Slides endpoints do the work: create-pdf-slides (10 + 100 credits per page at 2K), generate-narration (210 credits per page), and download-slides-pages-voices (free).
• A narrated 8-slide recap costs 2,490 credits, roughly $5 to $6.25 depending on the credit pack; the deck alone is 810 credits.
• Every write endpoint is limited to 6 requests per minute per key, so a 50-client run should be queued, not fired in parallel.
• Fast PPT (generate) cannot be narrated; for video, start from create-pdf-slides or create-like-this.

Who this is for

Marketing ops leads who rebuild the same recap deck every Monday, growth engineers who already have the metrics in a warehouse, and agencies that owe a weekly update to 20, 50, or more clients. The pain is the same: the numbers are ready by 6 a.m., the deck is ready by lunch, and half the stakeholders never open it.

Do not use this recipe if stakeholders need to edit the slides in PowerPoint afterward; the image-designed pipeline produces a finished PDF plus page images, not native PPTX. For editable weekly decks, the Fast PPT path in Automate weekly reports with Zapier and 2Slides fits better.

The workflow at a glance

Every 2Slides call uses the same Authorization: Bearer $SLIDES_API_KEY header, and every asynchronous job is polled at GET /api/v1/jobs/{jobId}.

Step 1: Get an API key and wire up the scheduler

Create a key at 2slides.com/api under the API Keys tab. New accounts get 500 free credits with no subscription, enough to run this pipeline once end to end before buying a pack. Store the key as SLIDES_API_KEY in your scheduler's secret store, never in a browser or a shared notebook, and confirm it with the echo endpoint before scheduling anything.

Figure 1: The API reference at 2slides.com/api lists every endpoint, the Bearer header, and credit costs.

For the trigger, a GitHub Actions workflow with on: schedule: - cron: "0 6 * * 1" is enough for a handful of clients. For 50 or more, put clients in a queue and let one worker drain it sequentially, which keeps you under the 6 requests per minute limit with room for retries.

Step 2: Pull the metrics and let an LLM write the 8-slide narrative

The 2Slides API does not know what a good weekly recap says; that part is yours, and it decides the quality of the deck. Pull last week's numbers from your ad platforms or warehouse into one flat JSON object per client, then prompt your LLM to return exactly eight titled sections:

1. Headline result: one number, one sentence ("CPA down 18% week over week at flat spend").
2. Spend vs. plan: actual, planned, variance, pacing to month.
3. Top channels: three channels with spend, conversions, CPA, and the change.
4. Creative winners: the two or three ads that converted best and why.
5. Audience and geo notes: what shifted.
6. Tests running: hypothesis, status, read date.
7. Risks and blockers: budget caps, tracking gaps, seasonality.
8. Next week's plan: three bullets with owners.

Ask for plain sentences with the numbers inline and under 60 words per section. create-pdf-slides treats your text as the source of truth for copy and layout, so a clean 400 to 500 word narrative produces a tighter deck than a 3,000 word dump of every metric.

Step 3: Campaign report deck automation with create-pdf-slides

Send the narrative to create-pdf-slides. Set page: 8 so the slide count matches your eight sections, aspectRatio: "16:9" for screens, and resolution: "2K" so the PNGs hold up at 1920×1080 without upscaling. designStyle is where your brand lives: colors, type feel, layout rules, and what to avoid.

The response is { "jobId": "..." }. Poll GET https://2slides.com/api/v1/jobs/{jobId} every 5 to 10 seconds until status is success (the PDF is at downloadUrl) or failed. Expect a few minutes for eight 2K pages. Cost: 10 planning credits plus 100 per page, so 810 credits for the 8-page deck.

To match an existing brand slide instead of a text description, swap to create-like-this with referenceImageUrl pointing at a public image of one on-brand slide. Body, cost, and limits are otherwise identical.

Step 4: Two speakers with the narrated video presentation API

Once the deck job reports success, call generate-narration on the same jobId. Use mode: "multi" with two named speakers and two of the 30 available voices; Kore and Puck sit far enough apart that listeners can follow who is talking without a visual cue. includeIntro: true adds a short opener that names the client and the week.

The endpoint answers 202 and the job goes back to processing. Poll the same jobId until it returns success again. Narration costs 210 credits per page (10 for the script, 200 for the audio), so 1,680 credits for eight slides. For script length and pacing guidance, see Slides narration and video best practices.

One comparison, since people ask: Gamma's developer site (https://developers.gamma.app) documents a narrated-video recipe that chains n8n, Synthesia, ElevenLabs, and its own Generate API, and its API keys require the Pro plan. The 2Slides route above uses one vendor and one key that works on any account, with ffmpeg on your side for assembly; it does not produce an avatar presenter the way a Synthesia layer does. Disclosure: 2Slides is our product.

Step 5: Turn the weekly marketing report to video with ffmpeg

Call download-slides-pages-voices with the same jobId. It returns a free ZIP containing pages/page_01.png through page_08.png, voices/page_01.wav through page_08.wav, and transcript.txt with the spoken script for captions or an email summary.

Then stitch each PNG to its WAV and concatenate. This one-liner produces a 1920×1080 H.264 MP4 where each slide stays on screen exactly as long as its narration:

The concat demuxer at the end is documented in the ffmpeg formats reference. For a vertical cut, change both 1920:1080 values to 1080:1920 and regenerate the deck with aspectRatio: "9:16".

No worker with ffmpeg? Open the same job in the 2Slides Workspace and use Export, then Generate Video. It renders the H.264 MP4 at 1920×1080 or 1080×1920 in the browser for 20 credits per page (160 for an 8-slide recap). That suits a one-off; ffmpeg suits 50 clients every Monday.

Step 6: The Node.js pipeline to automate marketing report presentations

The whole thing as one Node 20 script with no dependencies beyond fetch. Replace loadMetrics and writeNarrative with your warehouse query and LLM call.

Each client costs three write requests (deck, narration, download) plus polling reads on a separate 10 requests per minute allowance.

Picking a reference style

If describing your brand in designStyle is not landing, use a reference image. The 2Slides Gallery hosts real-world decks you can browse for direction or pass to create-like-this as referenceImageUrl. These are reference decks, not API output: the slides below come from an Adobe Creative Trends 2026 deck in the Gallery and show the restrained, data-forward style that reads well in a weekly recap.

Figure 3: Cover slide of the Adobe Creative Trends 2026 reference deck in the 2Slides Gallery.

Figure 4: An interior slide from the same Gallery deck. Pass a slide like this as referenceImageUrl and create-like-this derives colors, type, and layout from it.

Figure 5: The 2Slides Gallery. Open a deck and copy the image URL of the slide whose look you want to inherit.

For agencies, store one reference slide URL per client next to their metrics config, and every Monday deck stays in that client's visual system.

What it costs

Per 8-slide recap: 810 credits for the 2K deck, 1,680 for narration, nothing for the ZIP or for ffmpeg on your own worker. Credit packs run from $5 for 2,000 credits ($0.0025 each) to $80 for 40,000 credits ($0.002 each).

Two notes. Dropping to resolution: "1K" saves nothing (100 credits per page applies to 512px, 1K, and 2K; only 4K doubles it), so stay at 2K. Rendering the MP4 in the Workspace instead of ffmpeg adds 160 credits ($0.32 to $0.40) per recap.

Fast PPT or image-designed slides for this use case?

Many teams run both: a Fast PPT deck for the account manager who annotates it, and the narrated video for the client who watches on a phone. How marketing teams generate AI presentation decks at scale covers the editable side in depth.

Common pitfalls

• Firing 50 clients in parallel. Every write endpoint allows 6 requests per minute per key. Queue clients and process them sequentially, or spread submissions across the hour.
• Calling generate-narration on a Fast PPT job. Narration only accepts jobs from create-pdf-slides or create-like-this; a generate job is rejected and cannot be converted.
• Putting the API key in a browser dashboard. Keep SLIDES_API_KEY on the server or in your scheduler's secret store. If a client-facing page needs the video, serve the MP4 you already rendered.
• Using page: 0 when you want exactly eight slides. 0 means auto-detect the page count. Set page: 8 so every week's video has the same shape and length.
• Passing a language code. responseLanguage takes a name such as "Spanish", not "es". Store the name in each client's config.
• Sending the raw metrics export. A 3,000-row CSV pasted into userInput produces a muddled deck. Summarize first, hand over a 400 to 500 word narrative, and keep the CSV as an attachment.

Frequently Asked Questions

How much does it cost to automate a weekly marketing report as a narrated video?

A narrated 8-slide recap costs 2,490 credits, between $4.98 and $6.23 depending on the credit pack. That breaks down to 810 credits for the 2K image-designed deck (10 planning plus 100 per page) and 1,680 credits for two-speaker narration (210 per page). The per-page PNG and WAV download is free, and stitching with ffmpeg on your own machine adds nothing.

Can an AI voiceover slides API use two different voices in one deck?

Yes. generate-narration with mode: "multi" takes speaker1Name, speaker2Name, speaker1Voice, and speaker2Voice, and alternates the two speakers through the slides. There are 30 voices to choose from, including Kore, Puck, Zephyr, Charon, Aoede, and Leda. Use mode: "single" with speakerName and voice when one narrator is enough, at the same 210 credits per page.

Which endpoints does a narrated video presentation API pipeline need?

Three, in order: POST /api/v1/slides/create-pdf-slides (or create-like-this with a referenceImageUrl) to design the deck, POST /api/v1/slides/generate-narration on the resulting jobId to add audio, and POST /api/v1/slides/download-slides-pages-voices to fetch the PNG and WAV pairs. Poll GET /api/v1/jobs/{jobId} every 5 to 10 seconds between steps. Fast PPT's generate is not part of this chain because it cannot be narrated.

Can I deliver the same weekly report in several languages?

Yes. Set responseLanguage on create-pdf-slides to a language name such as "Spanish" or "Japanese" and the slide copy is written in that language; narration follows the slide content. Over 20 languages are supported. Each language is a separate deck job, so a client who wants English and Spanish videos pays for two 2,490-credit runs.

How long does the Monday pipeline take per client?

Plan on several minutes per client: an 8-page 2K deck takes a few minutes to render, narration adds a few more, and ffmpeg assembly is typically under a minute for eight clips. Polling every 5 to 10 seconds and processing clients one at a time respects the 6 requests per minute limit, and a 50-client run started at 06:00 is normally finished before the first stand-up.
