# Examples Overview

> Gallery of 4 production use cases at different complexity levels — from a minimal web search tool to a multi-workflow RAG proposal generator

## Example gallery

These examples are based on production use cases deployed on the Codika platform. They demonstrate different trigger types, integration patterns, AI capabilities, and complexity levels.

| Example                                            | Complexity | Triggers        | Key features                                                     |
| -------------------------------------------------- | ---------- | --------------- | ---------------------------------------------------------------- |
| [Simple Web Search](/examples/simple-search)       | Minimal    | HTTP            | Single workflow, one API call, FLEXCRED credentials              |
| [Email Automation](/examples/email-automation)     | Medium     | Service event   | Gmail integration, Google Drive/Sheets, INSTPARM parameters      |
| [Scheduled CRM Report](/examples/scheduled-report) | Medium     | Schedule + HTTP | Dual triggers, Slack integration, deployment parameters          |
| [Proposal Generator (RAG)](/examples/complex-rag)  | Complex    | HTTP            | Multi-workflow, sub-workflows, RAG, file uploads, data ingestion |

## Patterns demonstrated

### Trigger types

* **HTTP webhook** — user-initiated via form (Simple Search, Proposal Generator)
* **Schedule (cron)** — time-based automation (CRM Report)
* **Service event** — external service triggers (Email Automation)
* **Sub-workflow** — helper called by parent (Proposal Generator)

### Credential types

* **FLEXCRED** — AI providers with org/Codika fallback (all AI examples)
* **USERCRED** — User's OAuth tokens (Email Automation)
* **ORGCRED** — Organization-level shared credentials (CRM Report)
* **INSTPARM** — User-configured deployment parameters (Email Automation, CRM Report)

### AI patterns

* **chainLlm** — Structured classification with output parser (Email Intelligence)
* **RAG retrieval** — Pinecone vector search for similar documents (Proposal Generator)
* **Text generation** — Claude-powered content creation (Proposal Generator)

### Advanced patterns

* **Multiple triggers** — Schedule + manual HTTP on same workflow (CRM Report)
* **Sub-workflows** — PDF generation as a reusable helper (Proposal Generator)
* **File uploads** — Generate and return files to users (Proposal Generator)
* **Data ingestion** — Document embedding pipeline for RAG (Proposal Generator)
* **Deployment parameters** — User-configurable installation settings (Email, CRM)

## Folder structure patterns

### Minimal (1 workflow)

```
simple-search/
  config.ts
  version.json
  project.json
  workflows/
    web-search.json
```

### Standard (1-2 workflows)

```
email-automation/
  config.ts
  version.json
  project.json
  workflows/
    email-processor.json
```

### Complex (multiple workflows + sub-workflows)

```
proposal-generator/
  config.ts
  version.json
  project.json
  workflows/
    proposal-generation.json
    document-retrieval.json
    pdf-converter.json          # Sub-workflow
```
