Supported Conversions

| source_type | target_type | Output | | ----------- | ----------- | ------ | | pdf | word | .docx | | pdf | excel | .xlsx |

Step 1: Upload PDF

BASE="https://ai-tools.camscanner.com"

IN_FILE_ID=$(curl -sS -X POST "$BASE/v1/tools/upload_file/execute" \
  -H "Content-Type: application/octet-stream" \
  --data-binary "@/path/to/document.pdf" | jq -r '.tool_result.data.file_id')

Response:

{
  "code": 200,
  "tool": "upload_file",
  "tool_result": {
    "success": true,
    "data": {
      "file_id": "file_1741857600_ab12cd34ef56",
      "size": 24576
    }
  }
}

Step 2: Convert PDF

OUT_FILE_ID=$(curl -sS -X POST "$BASE/v1/tools/convert_pdf/execute" \
  -H "Content-Type: application/json" \
  -d "{\"file_id\":\"$IN_FILE_ID\",\"source_type\":\"pdf\",\"target_type\":\"TARGET\",\"output_mode\":\"file_id\"}" \
  | jq -r '.tool_result.data.file_id')

Replace TARGET with one of: word, excel.

Response:

{
  "code": 200,
  "tool": "convert_pdf",
  "tool_result": {
    "success": true,
    "data": {
      "file_id": "file_1741857722_ddeeff001122",
      "target_type": "word"
    }
  }
}

Step 3: Download Result

curl -sS -X POST "$BASE/v1/tools/download_file/execute?response_mode=raw" \
  -H "Content-Type: application/json" \
  -d "{\"file_id\":\"$OUT_FILE_ID\"}" \
  -o /path/to/output.docx

Critical: The response_mode=raw query parameter is required to get the binary file. Without it, the response is JSON.

Quick Reference: Complete Pipeline

BASE="https://ai-tools.camscanner.com"
INPUT_PDF="/path/to/document.pdf"
TARGET_TYPE="word"          # word | excel
OUTPUT_FILE="/path/to/output.docx"

# Upload
IN_FILE_ID=$(curl -sS -X POST "$BASE/v1/tools/upload_file/execute" \
  -H "Content-Type: application/octet-stream" \
  --data-binary "@$INPUT_PDF" | jq -r '.tool_result.data.file_id')

# Convert
OUT_FILE_ID=$(curl -sS -X POST "$BASE/v1/tools/convert_pdf/execute" \
  -H "Content-Type: application/json" \
  -d "{\"file_id\":\"$IN_FILE_ID\",\"source_type\":\"pdf\",\"target_type\":\"$TARGET_TYPE\",\"output_mode\":\"file_id\"}" \
  | jq -r '.tool_result.data.file_id')

# Download
curl -sS -X POST "$BASE/v1/tools/download_file/execute?response_mode=raw" \
  -H "Content-Type: application/json" \
  -d "{\"file_id\":\"$OUT_FILE_ID\"}" \
  -o "$OUTPUT_FILE"

File Extension Mapping

| target_type | Extension | | ----------- | --------- | | word | .docx | | excel | .xlsx |

Common Mistakes

| Mistake | Fix | | ------------------------------------------ | ----------------------------------------------------------------------- | | Forgetting response_mode=raw on download | Always append ?response_mode=raw to the download URL | | Wrong Content-Type on upload | Upload uses application/octet-stream, not multipart/form-data | | Using GET instead of POST | All three endpoints use POST | | Missing source_type in convert request | Always include "source_type": "pdf" | | Missing output_mode in convert request | Always include "output_mode": "file_id" to get a downloadable file_id | | Wrong output extension | Match extension to target_type (see table above) |

Error Handling

Check each step before proceeding:

# After upload
if [ -z "$IN_FILE_ID" ] || [ "$IN_FILE_ID" = "null" ]; then
  echo "Upload failed"; exit 1
fi

# After convert
if [ -z "$OUT_FILE_ID" ] || [ "$OUT_FILE_ID" = "null" ]; then
  echo "Conversion failed"; exit 1
fi
