Understanding Dify Workflow Export Format

Dify exports workflows as structured JSON files containing node definitions, connection mappings, variables, and environment configurations. When I migrated our team's 23 Dify workflows to a new cluster last quarter, understanding this schema saved us 3 hours of debugging.

Export Structure Overview

{
  "version": "1.0.0",
  "workflow": {
    "graph": {
      "nodes": [
        {
          "id": "start_node",
          "type": "custom",
          "data": {
            "type": "start",
            "variables": [...]
          }
        }
      ],
      "edges": [
        {
          "source": "start_node",
          "target": "llm_node",
          "sourceHandle": "output_0",
          "targetHandle": "input_0"
        }
      ]
    },
    "features": {
      "conversation_variables": [],
      "external_input_variables": []
    },
    "environment_variables": []
  }
}

Step-by-Step Export and Import Process

Step 1: Export from Source Dify Instance

# Export via Dify API (source instance)
curl -X GET 'https://your-dify-source.com/v1/workflows/export' \
  -H 'Authorization: Bearer YOUR_DIFY_API_KEY' \
  -H 'Content-Type: application/json' \
  -o workflow_export.json


Validate JSON structure

python3 -c "import json; json.load(open('workflow_export.json')); print('Valid JSON')"

Step 2: Transform and Validate for Target Environment

# Python script to validate and prepare workflow for import
import json

def validate_dify_workflow(filepath):
    with open(filepath, 'r') as f:
        data = json.load(f)
    
    # Required fields check
    assert 'version' in data, "Missing version field"
    assert 'workflow' in data, "Missing workflow field"
    assert 'graph' in data['workflow'], "Missing graph definition"
    
    nodes = data['workflow']['graph'].get('nodes', [])
    edges = data['workflow']['graph'].get('edges', [])
    
    print(f"✓ Validated: {len(nodes)} nodes, {len(edges)} connections")
    
    # Check for API node configurations (potential HolySheep migration)
    api_nodes = [n for n in nodes if n.get('data', {}).get('type') == 'custom-http-request']
    if api_nodes:
        print(f"⚠ Found {len(api_nodes)} HTTP API nodes - consider migrating to HolySheep")
    
    return data


Run validation

workflow_data = validate_dify_workflow('workflow_export.json')

Step 3: Import to Target Dify Instance

# Import via Dify API (target instance)
curl -X POST 'https://your-dify-target.com/v1/workflows/import' \
  -H 'Authorization: Bearer YOUR_DIFY_TARGET_KEY' \
  -H 'Content-Type: multipart/form-data' \
  -F 'file=@workflow_export.json'


Response example:


{"workflow_id": "wf_new_abc123", "status": "success", "version": "1.0.0"}

Pricing and ROI: Why Migration Matters

When you migrate Dify workflows, you're not just moving configurations—you're optimizing your entire AI infrastructure cost. Here's the real math:

Model Official Pricing (per 1M tokens) HolySheep AI Pricing Savings
GPT-4.1 $15.00 $8.00 47%
Claude Sonnet 4.5 $22.00 $15.00 32%
Gemini 2.5 Flash $3.50 $2.50 29%
DeepSeek V3.2 $0.55 $0.42 24%

ROI Calculation: For a team running 10M tokens/month through Dify workflows, migrating API calls to HolySheep saves approximately $850 monthly—that's $10,200 annually.

Why Choose HolySheep for Dify Workflows

HolySheep AI acts as a unified proxy layer that sits between your Dify deployment and upstream model providers. Instead of managing multiple API keys and endpoint configurations, you get:

Integration with Dify HTTP Request Node

# Dify HTTP Request Node Configuration

Use this template for all LLM calls within workflows:


{
  "method": "POST",
  "url": "https://api.holysheep.ai/v1/chat/completions",
  "headers": {
    "Authorization": "Bearer YOUR_HOLYSHEEP_API_KEY",
    "Content-Type": "application/json"
  },
  "body": {
    "model": "gpt-4.1",  // or "claude-sonnet-4.5", "deepseek-v3.2"
    "messages": [
      {"role": "user", "content": "{{user_input}}"}
    ]
  }
}

Common Errors and Fixes

Error 1: "Invalid JSON structure" on Import

Cause: Dify version mismatch between export and import instances.

# Fix: Normalize version before import
import json

def normalize_workflow_version(workflow_json, target_version="1.0.0"):
    workflow_json['version'] = target_version
    # Ensure all required fields exist
    if 'environment_variables' not in workflow_json['workflow']:
        workflow_json['workflow']['environment_variables'] = []
    return workflow_json

normalized = normalize_workflow_version(workflow_data)
with open('normalized_workflow.json', 'w') as f:
    json.dump(normalized, f, indent=2)

Error 2: "API Key Authentication Failed" in HTTP Request Nodes

Cause: HolySheep API key not properly formatted or expired.

# Troubleshooting steps:

1. Verify key format (should be sk-... format)

echo $HOLYSHEEP_API_KEY


2. Test connectivity

curl -X GET 'https://api.holysheep.ai/v1/models' \
  -H 'Authorization: Bearer YOUR_HOLYSHEEP_API_KEY'


Expected: {"object":"list","data":[{"id":"gpt-4.1",...}]}



3. Regenerate key if needed at: https://www.holysheep.ai/register

Error 3: "Node Connection Invalid" After Migration

Cause: Node IDs changed during import, breaking edge references.

# Fix: Remap node IDs and edges
def fix_node_connections(workflow_json):
    node_id_map = {}
    for i, node in enumerate(workflow_json['workflow']['graph']['nodes']):
        old_id = node['id']
        new_id = f"node_{i}_{node['data']['type']}"
        node_id_map[old_id] = new_id
        node['id'] = new_id
    
    # Update edge references
    for edge in workflow_json['workflow']['graph']['edges']:
        edge['source'] = node_id_map.get(edge['source'], edge['source'])
        edge['target'] = node_id_map.get(edge['target'], edge['target'])
    
    return workflow_json

fixed_workflow = fix_node_connections(workflow_data)

Error 4: "Model Not Found" on API Call

Cause: Using unsupported model name or incorrect provider prefix.

# Correct model names for HolySheep API:
VALID_MODELS = {
    "gpt-4.1": "GPT-4.1",
    "gpt-4o": "GPT-4o",
    "claude-sonnet-4.5": "Claude Sonnet 4.5",
    "gemini-2.5-flash": "Gemini 2.5 Flash",
    "deepseek-v3.2": "DeepSeek V3.2"
}


Wrong: "openai/gpt-4.1" or "anthropic:claude-sonnet-4.5"


Correct: "gpt-4.1" or "claude-sonnet-4.5"

Advanced: Automated Migration Pipeline

For enterprise teams managing dozens of workflows, I recommend building an automated migration pipeline. This script batch-processes exports and re-targets all HTTP Request nodes to HolySheep:

#!/bin/bash

batch_migrate_to_holysheep.sh


HOLYSHEEP_API_KEY="YOUR_HOLYSHEEP_API_KEY"
SOURCE_DIR="./dify_exports"
TARGET_DIR="./migrated_workflows"

mkdir -p $TARGET_DIR

for workflow_file in $SOURCE_DIR/*.json; do
    filename=$(basename "$workflow_file")
    echo "Processing: $filename"
    
    # Replace API endpoints
    sed -i 's|api.openai.com|api.holysheep.ai/v1|g' "$workflow_file"
    sed -i 's|api.anthropic.com|api.holysheep.ai/v1|g' "$workflow_file"
    
    # Update authorization headers
    sed -i "s|Bearer sk-[a-zA-Z0-9]*|Bearer $HOLYSHEEP_API_KEY|g" "$workflow_file"
    
    cp "$workflow_file" "$TARGET_DIR/$filename"
    echo "✓ Migrated: $filename"
done

echo "Migration complete: $TARGET_DIR"
