Workflow Overview

CLI Approach

Step 1: Authenticate

# Login with 3-legged OAuth (opens browser)
raps auth login

# Or use existing refresh token
raps auth refresh

Step 2: Navigate Project Hierarchy

# List all hubs (accounts)
raps hub list

# Save hub ID
HUB_ID="b.your-hub-id"

# List projects in hub
raps project list "$HUB_ID"

# Save project ID
PROJECT_ID="b.your-project-id"

# List top-level folders
raps folder list "$PROJECT_ID" --top

# List contents of specific folder
FOLDER_ID="urn:adsk.wipprod:fs.folder:abc123"
raps folder list "$PROJECT_ID" "$FOLDER_ID"

Step 3: Download Files

# List items in folder
raps folder list "$PROJECT_ID" "$FOLDER_ID" --output json > items.json

# Download specific item
ITEM_ID=$(jq -r '.[0].id' items.json)
raps item download "$PROJECT_ID" "$ITEM_ID" --output ./downloads/

# Download all items in folder
jq -r '.[].id' items.json | while read item_id; do
  raps item download "$PROJECT_ID" "$item_id" --output ./downloads/
done

Step 4: Get Version History

# List all versions of an item
raps item versions "$PROJECT_ID" "$ITEM_ID" --output json > versions.json

# Download specific version
VERSION_ID=$(jq -r '.[0].id' versions.json)
raps item download "$PROJECT_ID" "$ITEM_ID" --version "$VERSION_ID" --output ./downloads/

Common Patterns

Incremental Sync

# Track last sync time
LAST_SYNC=$(cat .last-sync 2>/dev/null || echo "1970-01-01")

# Get items modified since last sync
raps folder list "$PROJECT_ID" "$FOLDER_ID" --output json | \
  jq --arg since "$LAST_SYNC" '[.[] | select(.lastModified > $since)]' | \
  jq -r '.[].id' | while read item_id; do
    raps item download "$PROJECT_ID" "$item_id" --output ./synced/
  done

# Update last sync time
date -Iseconds > .last-sync

Mirror Folder Structure

# Recursively sync folder structure
sync_folder() {
  local project_id=$1
  local folder_id=$2
  local local_path=$3

  mkdir -p "$local_path"

  raps folder list "$project_id" "$folder_id" --output json | while read -r item; do
    type=$(echo "$item" | jq -r '.type')
    name=$(echo "$item" | jq -r '.name')
    id=$(echo "$item" | jq -r '.id')

    if [ "$type" = "folders" ]; then
      sync_folder "$project_id" "$id" "$local_path/$name"
    else
      raps item download "$project_id" "$id" --output "$local_path/"
    fi
  done
}

sync_folder "$PROJECT_ID" "$FOLDER_ID" "./local-mirror"
