Examples

Every template_slide_id comes from template analysis. If you upload a fresh copy of the template, replace the demo slide_* values with the slideId values returned for your upload.

Visual Overview

Generation starts with a PowerPoint template and a deck request JSON. The template supplies the reusable slide layouts; the JSON supplies the content and rendering options.

Input	What it contributes
PowerPoint template	Slide layouts, fonts, placeholder positions, table styling, chart containers, and footer/page-number placement
Deck request JSON	Agenda sections, table rows, text commentary, logo cells, chart categories, chart series, conditional formatting, and generation options
Generated `.pptx`	A populated deck that keeps the template styling while replacing placeholders with the request content

The output deck renders one logical slide per request slide:

Output slide	Generated title	Template layout	Main input blocks
1	Agenda	Agenda	`agenda`
2	Customer Health: Enterprise Strong, SMB Fragile	Table + text	`table`, `text`
3	Renewal Outlook: Enterprise Expansions Anchor 2025 Book	Table-only	`table`
4	Customer Advisory Board: 20 Reference Conversations	Logo table	`table` with `is_logo` cells
5	Helix AI Copilot: Strong Enterprise Pull, Mid-Market Headwinds	Two-column chart + table	`chart`, `table`
6	Net Promoter Score by Customer	Chart + text	`chart`, `text`

Full Deck Walkthrough

1. Set Request Variables

export API_BASE="https://your-api.example.com"
export API_KEY="your-api-key"
export TEMPLATE_PATH="/path/to/template.pptx"
export DATA_PATH="/path/to/deck-request.json"
export OUTPUT_PATH="generated-deck.pptx"

2. Upload the Template

Upload your PowerPoint template once. The API returns a template_id plus a signed upload URL.

export TEMPLATE_SIZE=$(wc -c < "$TEMPLATE_PATH" | tr -d ' ')

curl -sS -X POST "$API_BASE/api/v1/templates" \
  -H "X-API-Key: $API_KEY" \
  -H "Content-Type: application/json" \
  --data "{
    \"filename\": \"customer-diligence-template.pptx\",
    \"file_size\": $TEMPLATE_SIZE,
    \"metadata\": {
      \"category\": \"demo\",
      \"tags\": [\"voice-of-customer\"],
      \"description\": \"Demo template with agenda, tables, logos, and charts\"
    }
  }" \
  -o template-upload.json

export TEMPLATE_ID=$(jq -r '.template_id' template-upload.json)
export UPLOAD_URL=$(jq -r '.upload_url' template-upload.json)

curl -sS -X PUT "$UPLOAD_URL" \
  -H "Content-Type: application/vnd.openxmlformats-officedocument.presentationml.presentation" \
  --upload-file "$TEMPLATE_PATH"

curl -sS -X POST "$API_BASE/api/v1/templates/$TEMPLATE_ID/upload/confirm" \
  -H "X-API-Key: $API_KEY"

3. Analyze the Template

Analysis reads the PowerPoint file and assigns a slideId to each template slide. Those IDs are what the generation request uses as template_slide_id.

curl -sS -X POST "$API_BASE/api/v1/templates/$TEMPLATE_ID/analysis" \
  -H "X-API-Key: $API_KEY" \
  -H "Content-Type: application/json" \
  --data '{
    "options": {
      "parse_master_template_layout": true,
      "parse_slides": true,
      "include_placeholder_positions": true,
      "include_table_details": true
    }
  }'

Poll the analysis endpoint until it returns a completed result:

curl -sS "$API_BASE/api/v1/templates/$TEMPLATE_ID/analysis" \
  -H "X-API-Key: $API_KEY" \
  -o template-analysis.json

Print the analyzed slide IDs:

jq -r '(.results.slides // .slides)[] | "\(.slideNumber)\t\(.slideId)"' template-analysis.json

Example output:

slide_11d45035
slide_52292b72
slide_93106c67
slide_f53f7a49
slide_353000d7
slide_cfb80823

Each slideId is a stable identifier you pass as template_slide_id in generation requests. The actual values are short hex strings — for readability, the rest of this guide uses semantic names (slide_agenda, slide_table_only, etc.) in place of those IDs. The generated output uses this layout mapping:

Placeholder used in this guide	Real ID example	Template slot	Used by demo slide
`slide_agenda`	`slide_cfb80823`	Agenda	Agenda
`slide_table_text`	`slide_52292b72`	Table + text	Customer health
`slide_table_only`	`slide_11d45035`	Table-only	Renewal outlook
`slide_logo_table`	`slide_93106c67`	Logo table	Customer advisory board
`slide_chart_table`	`slide_f53f7a49`	Two-column chart + table	Helix AI Copilot
`slide_chart_text`	`slide_353000d7`	Chart + text	Net Promoter Score

When you upload the template yourself, swap the semantic placeholders in the request below for whatever slideId values your analysis returns.

4. Review the Deck Request

The deck request JSON is shaped for generate-deck. The outer object has slides and deck-level options.

Request spine

{
  "slides": [
    {
      "template_slide_id": "slide_agenda",
      "slide_data": {
        "title": "Agenda",
        "content": { "blocks": [{ "type": "agenda" }] }
      }
    },
    {
      "template_slide_id": "slide_table_text",
      "slide_data": {
        "title": "Customer Health: Enterprise Strong, SMB Fragile",
        "content": { "blocks": [{ "type": "table" }, { "type": "text" }] }
      },
      "options": {
        "auto_paginate_tables": false,
        "allow_textbox_reposition": true,
        "table_min_font_size": 8,
        "textbox_min_font_size": 11
      }
    },
    {
      "template_slide_id": "slide_table_only",
      "slide_data": {
        "title": "Renewal Outlook: Enterprise Expansions Anchor 2025 Book",
        "content": { "blocks": [{ "type": "table" }] }
      },
      "options": {
        "auto_paginate_tables": true,
        "table_min_font_size": 9
      }
    },
    {
      "template_slide_id": "slide_logo_table",
      "slide_data": {
        "title": "Customer Advisory Board: 20 Reference Conversations",
        "content": { "blocks": [{ "type": "table" }] }
      },
      "options": {
        "auto_paginate_tables": true,
        "table_min_font_size": 11
      }
    },
    {
      "template_slide_id": "slide_chart_table",
      "slide_data": {
        "title": "Helix AI Copilot: Strong Enterprise Pull, Mid-Market Headwinds",
        "content": [
          { "header": "Consideration Status by Customer Segment", "blocks": [{ "type": "chart" }] },
          { "header": "Voice of Customer", "blocks": [{ "type": "table" }] }
        ]
      },
      "options": { "auto_paginate_tables": false }
    },
    {
      "template_slide_id": "slide_chart_text",
      "slide_data": {
        "title": "Net Promoter Score by Customer",
        "content": { "blocks": [{ "type": "chart" }, { "type": "text" }] }
      },
      "options": { "auto_paginate_tables": false }
    }
  ],
  "options": {
    "auto_paginate_tables": true,
    "table_min_font_size": 9,
    "textbox_min_font_size": 11,
    "show_slide_numbers": true,
    "footer_text": "Helix Customer Diligence | Investment Committee Pre-Read | Confidential"
  }
}

The full file contains the actual rows, quotes, conditional formatting, and chart values. Key patterns:

Slide	What the JSON controls
Agenda	`agenda.sections` supplies the five agenda labels. `active_index: 0` marks the first section active, and `active_font_color` controls the active label color.
Customer health	A 20-row table is populated, then status columns use `column_configs` and `format_templates` to color health, engagement, adoption, and expansion cells. A `text` block fills the commentary box.
Renewal outlook	A table-only layout receives eight account rows with mixed cell content: bullet paragraphs plus italic quote paragraphs. `auto_paginate_tables: true` allows continuation pages if the table overflows.
Advisory board	A 21-row contact table uses `is_logo: true` cells to fetch and render company logos where domains are provided. Name/title styling comes from reusable `format_templates`.
Helix AI Copilot	Two-column `content` sends a percent stacked column chart to one side and a Voice of Customer table to the other. Chart `series[].color`, `show_bar_labels`, and `data_rows` drive the visual chart details.
NPS	A full-width percent stacked column chart receives eight customer categories, three NPS series, chart labels, and data rows. A trailing `text` block renders the survey note.

5. Generate the Deck

Submit the JSON file to the async deck-generation endpoint:

curl -sS -X POST "$API_BASE/api/v1/presentations/generate-deck" \
  -H "X-API-Key: $API_KEY" \
  -H "Content-Type: application/json" \
  --data @"$DATA_PATH" \
  -o generation-start.json

The response returns a generation_id and status_url.

{
  "generation_id": "gen_abc123",
  "status": "pending",
  "message": "Generation started. Poll status URL for progress.",
  "status_url": "https://your-api.example.com/api/v1/presentations/gen_abc123/status"
}

6. Poll for Completion

export GENERATION_ID=$(jq -r '.generation_id' generation-start.json)

curl -sS "$API_BASE/api/v1/presentations/$GENERATION_ID/status" \
  -H "X-API-Key: $API_KEY" \
  -o generation-status.json

Repeat the status request until status is completed or partial. The completed result includes total_pages_generated, per-slide results, and a download_url.

{
  "generation_id": "gen_abc123",
  "status": "completed",
  "total_slides_requested": 6,
  "total_pages_generated": 6,
  "slide_results": [
    { "slide_index": 0, "template_slide_id": "slide_agenda", "pages_generated": 1, "status": "completed", "error": null },
    { "slide_index": 1, "template_slide_id": "slide_table_text", "pages_generated": 1, "status": "completed", "error": null },
    { "slide_index": 2, "template_slide_id": "slide_table_only", "pages_generated": 1, "status": "completed", "error": null },
    { "slide_index": 3, "template_slide_id": "slide_logo_table", "pages_generated": 1, "status": "completed", "error": null },
    { "slide_index": 4, "template_slide_id": "slide_chart_table", "pages_generated": 1, "status": "completed", "error": null },
    { "slide_index": 5, "template_slide_id": "slide_chart_text", "pages_generated": 1, "status": "completed", "error": null }
  ],
  "download_url": "https://storage.example.com/download/gen_abc123.pptx?token=..."
}

7. Download the Output

curl -L "$API_BASE/api/v1/presentations/$GENERATION_ID/download" \
  -H "X-API-Key: $API_KEY" \
  -o "$OUTPUT_PATH"

The downloaded file should match the expected deck shape: six populated slides, template styling inherited from the uploaded template, slide numbers enabled, and the deck-level footer applied across the output.

Equivalent Helper Flow

An SDK helper or demo script should perform the same operations:

Upload the template.
Analyze the uploaded template and read the six slideId values.
Load the deck request JSON.
Ensure each slide points at the template slide with the matching layout.
Call generate-deck, poll status, and download the finished .pptx.

Use the raw API steps above when you want to integrate generation into your own app. Use a helper script when you want a repeatable local smoke test.
