What this skill does

## Troubleshooting

If requests fail, run `zero doctor check-connector --env-name DIFY_TOKEN` or `zero doctor check-connector --url https://api.dify.ai/v1/chat-messages --method POST`

## Chat Messages

### Send Chat Message (Blocking)

Write to `/tmp/dify_request.json`:

```json
{
  "inputs": {},
  "query": "What is Dify?",
  "response_mode": "blocking",
  "user": "user-123"
}
```

Then run:

```bash
curl -s -X POST "https://api.dify.ai/v1/chat-messages" --header "Authorization: Bearer $DIFY_TOKEN" --header "Content-Type: application/json" -d @/tmp/dify_request.json | jq .
```

### Send Chat Message (Streaming)

Write to `/tmp/dify_request.json`:

```json
{
  "inputs": {},
  "query": "Explain quantum computing simply",
  "response_mode": "streaming",
  "user": "user-123"
}
```

Then run:

```bash
curl -s -X POST "https://api.dify.ai/v1/chat-messages" --header "Authorization: Bearer $DIFY_TOKEN" --header "Content-Type: application/json" -d @/tmp/dify_request.json
```

Streaming returns Server-Sent Events (SSE) with incremental chunks.

### Continue a Conversation

To continue an existing conversation, include the `conversation_id` from the first response:

Write to `/tmp/dify_request.json`:

```json
{
  "inputs": {},
  "query": "Tell me more about that",
  "response_mode": "blocking",
  "conversation_id": "{conversation_id}",
  "user": "user-123"
}
```

Then run:

```bash
curl -s -X POST "https://api.dify.ai/v1/chat-messages" --header "Authorization: Bearer $DIFY_TOKEN" --header "Content-Type: application/json" -d @/tmp/dify_request.json | jq .
```

### Stop Chat Message Generation

```bash
curl -s -X POST "https://api.dify.ai/v1/chat-messages/{task_id}/stop" --header "Authorization: Bearer $DIFY_TOKEN" --header "Content-Type: application/json" -d '{"user": "user-123"}' | jq .
```

## Text Completion

### Create Completion Message

Write to `/tmp/dify_request.json`:

```json
{
  "inputs": {
    "text": "Summarize the following: Dify is an open-source LLM app development platform."
  },
  "response_mode": "blocking",
  "user": "user-123"
}
```

Then run:

```bash
curl -s -X POST "https://api.dify.ai/v1/completion-messages" --header "Authorization: Bearer $DIFY_TOKEN" --header "Content-Type: application/json" -d @/tmp/dify_request.json | jq .
```

The `inputs` object keys depend on the variables configured in your Dify app's prompt template.

## Workflow Execution

### Execute Workflow (Blocking)

Write to `/tmp/dify_request.json`:

```json
{
  "inputs": {
    "query": "Analyze this data and provide insights"
  },
  "response_mode": "blocking",
  "user": "user-123"
}
```

Then run:

```bash
curl -s -X POST "https://api.dify.ai/v1/workflows/run" --header "Authorization: Bearer $DIFY_TOKEN" --header "Content-Type: application/json" -d @/tmp/dify_request.json | jq .
```

Response includes `workflow_run_id`, `status`, `outputs`, `elapsed_time`, and `total_tokens`.

### Execute Workflow (Streaming)

Write to `/tmp/dify_request.json`:

```json
{
  "inputs": {
    "query": "Generate a report on AI trends"
  },
  "response_mode": "streaming",
  "user": "user-123"
}
```

Then run:

```bash
curl -s -X POST "https://api.dify.ai/v1/workflows/run" --header "Authorization: Bearer $DIFY_TOKEN" --header "Content-Type: application/json" -d @/tmp/dify_request.json
```

### Get Workflow Run Detail

```bash
curl -s -X GET "https://api.dify.ai/v1/workflows/run/{workflow_run_id}" --header "Authorization: Bearer $DIFY_TOKEN" | jq .
```

## Conversations

### List Conversations

```bash
curl -s -X GET "https://api.dify.ai/v1/conversations?user=user-123&limit=20" --header "Authorization: Bearer $DIFY_TOKEN" | jq .
```

### Get Conversation History Messages

```bash
curl -s -X GET "https://api.dify.ai/v1/messages?user=user-123&conversation_id={conversation_id}&limit=20" --header "Authorization: Bearer $DIFY_TOKEN" | jq .
```

### Delete Conversation

```bash
curl -s -X DELETE "https://api.dify.ai/v1/conversations/{conversation_id}" --header "Authorization: Bearer $DIFY_TOKEN" --header "Content-Type: application/json" -d '{"user": "user-123"}' | jq .
```

### Rename Conversation

```bash
curl -s -X POST "https://api.dify.ai/v1/conversations/{conversation_id}/name" --header "Authorization: Bearer $DIFY_TOKEN" --header "Content-Type: application/json" -d '{"name": "My Chat Session", "user": "user-123"}' | jq .
```

## Message Feedback

```bash
curl -s -X POST "https://api.dify.ai/v1/messages/{message_id}/feedbacks" --header "Authorization: Bearer $DIFY_TOKEN" --header "Content-Type: application/json" -d '{"rating": "like", "user": "user-123"}' | jq .
```

Rating values: `like`, `dislike`, or `null` (to remove feedback).

## Suggested Questions

Get follow-up question suggestions after a message:

```bash
curl -s -X GET "https://api.dify.ai/v1/messages/{message_id}/suggested?user=user-123" --header "Authorization: Bearer $DIFY_TOKEN" | jq .
```

## File Upload

Upload a file for use in conversations:

```bash
curl -s -X POST "https://api.dify.ai/v1/files/upload" --header "Authorization: Bearer $DIFY_TOKEN" -F "file=@/path/to/file.png" -F "user=user-123" | jq .
```

Use the returned `id` in chat messages by adding it to the `files` array in the request body.

## Application Info

### Get Application Parameters

```bash
curl -s -X GET "https://api.dify.ai/v1/parameters?user=user-123" --header "Authorization: Bearer $DIFY_TOKEN" | jq .
```

### Get Application Meta Info

```bash
curl -s -X GET "https://api.dify.ai/v1/meta?user=user-123" --header "Authorization: Bearer $DIFY_TOKEN" | jq .
```

## Knowledge Base Management

Knowledge base APIs use a separate **Dataset API key** (not the app API key). Generate it from the Knowledge page's API section.

### Create Knowledge Base

```bash
curl -s -X POST "https://api.dify.ai/v1/datasets" --header "Authorization: Bearer $DIFY_TOKEN" --header "Content-Type: application/json" -d '{"name": "My Knowledge Base"}' | jq .
```

### List Knowledge Bases

```bash
curl -s -X GET "https://api.dify.ai/v1/datasets?page=1&limit=20" --header "Authorization: Bearer $DIFY_TOKEN" | jq .
```

### Delete Knowledge Base

```bash
curl -s -X DELETE "https://api.dify.ai/v1/datasets/{dataset_id}" --header "Authorization: Bearer $DIFY_TOKEN" | jq .
```

### Create Document by Text

Write to `/tmp/dify_request.json`:

```json
{
  "name": "example-document",
  "text": "This is the content of the document to be indexed.",
  "indexing_technique": "high_quality",
  "process_rule": {
    "mode": "automatic"
  }
}
```

Then run:

```bash
curl -s -X POST "https://api.dify.ai/v1/datasets/{dataset_id}/document/create_by_text" --header "Authorization: Bearer $DIFY_TOKEN" --header "Content-Type: application/json" -d @/tmp/dify_request.json | jq .
```

### List Documents in Knowledge Base

```bash
curl -s -X GET "https://api.dify.ai/v1/datasets/{dataset_id}/documents?page=1&limit=20" --header "Authorization: Bearer $DIFY_TOKEN" | jq .
```

### Delete Document

```bash
curl -s -X DELETE "https://api.dify.ai/v1/datasets/{dataset_id}/documents/{document_id}" --header "Authorization: Bearer $DIFY_TOKEN" | jq .
```

### Query Knowledge Base (Retrieval)

Write to `/tmp/dify_request.json`:

```json
{
  "query": "What is machine learning?",
  "retrieval_model": {
    "search_method": "semantic_search",
    "reranking_enable": false
  },
  "top_k": 3
}
```

Then run:

```bash
curl -s -X POST "https://api.dify.ai/v1/datasets/{dataset_id}/retrieve" --header "Authorization: Bearer $DIFY_TOKEN" --header "Content-Type: application/json" -d @/tmp/dify_request.json | jq .
```

## Guidelines

1. **Each app has its own API key** starting with `app-`. Generate keys from the app's API Access page
2. **Knowledge base APIs use a separate key** generated from the Knowledge page's API section
3. **Use `response_mode: "blocking"`** for simple integrations; use `"streaming"` for real-time UI
4. **Conversation continuity** requires passing `conversation_id` from previous responses
5. **The `user` field
