+# OpenAPI/Swagger Documentation Maintenance Guide
+
+## INT-010: Add API documentation (OpenAPI/Swagger)
+
+**Date**: 2025-12-25  
+**Status**: Completed
+
+## Summary
+
+This guide explains how to maintain OpenAPI/Swagger documentation for the Veza backend API. Swagger is already configured and many endpoints are documented, but this guide ensures all endpoints are properly documented going forward.
+
+## Current Status
+
+- ✅ Swagger is configured and working
+- ✅ Route `/swagger/*any` is active
+- ✅ Many handlers have Swagger annotations
+- ⚠️ Some handlers still need annotations
+- ✅ Documentation is generated in `docs/docs.go`, `docs/swagger.json`, `docs/swagger.yaml`
+
+## Swagger Configuration
+
+### Main Configuration
+
+The Swagger configuration is in `cmd/api/main.go`:
+
+```go
+// @title           Veza Backend API
+// @version         1.2.0
+// @description     Backend API for Veza platform.
+// @host            localhost:8080
+// @BasePath        /api/v1
+// @securityDefinitions.apikey BearerAuth
+// @in header
+// @name Authorization
+```
+
+### Route Setup
+
+Swagger UI is available at `/swagger/index.html` and configured in `internal/api/router.go`:
+
+```go
+router.GET("/swagger/*any", ginSwagger.WrapHandler(swaggerFiles.Handler))
+```
+
+## Adding Swagger Annotations
+
+### Basic Annotation Format
+
+Every handler function should have Swagger annotations above it:
+
+```go
+// @Summary      Short description
+// @Description  Detailed description
+// @Tags         TagName
+// @Accept       json
+// @Produce      json
+// @Param        param_name path/query/body type required "Description"
+// @Success      200  {object}  handlers.APIResponse{data=object{field=type}}
+// @Failure      400  {object}  handlers.APIResponse "Error description"
+// @Failure      401  {object}  handlers.APIResponse "Unauthorized"
+// @Router       /endpoint/path [method]
+func (h *Handler) HandlerFunc() gin.HandlerFunc {
+    // Handler implementation
+}
+```
+
+### Annotation Fields
+
+- **@Summary**: Short one-line description (required)
+- **@Description**: Detailed description (optional but recommended)
+- **@Tags**: Category/group for the endpoint (e.g., "Auth", "Track", "User")
+- **@Accept**: Content types accepted (json, multipart/form-data, etc.)
+- **@Produce**: Content types produced (json)
+- **@Param**: Request parameters
+  - Format: `@Param name location type required "description"`
+  - Location: `path`, `query`, `body`, `formData`, `header`
+  - Type: `string`, `int`, `bool`, `object`, etc.
+- **@Success**: Success response
+  - Format: `@Success status {type} "description"`
+  - Type: `object`, `array`, `string`, etc.
+- **@Failure**: Error responses
+- **@Router**: Endpoint path and HTTP method
+- **@Security**: Security requirements (e.g., `@Security BearerAuth`)
+
+### Example: Complete Handler Annotation
+
+```go
+// SearchLogs recherche des logs d'audit
+// @Summary      Search audit logs
+// @Description  Search and filter audit logs with pagination support
+// @Tags         Audit
+// @Accept       json
+// @Produce      json
+// @Security     BearerAuth
+// @Param        action      query     string  false  "Filter by action"
+// @Param        resource    query     string  false  "Filter by resource type"
+// @Param        start_date  query     string  false  "Start date (YYYY-MM-DD)"
+// @Param        end_date    query     string  false  "End date (YYYY-MM-DD)"
+// @Param        page        query     int     false  "Page number" default(1)
+// @Param        limit       query     int     false  "Items per page" default(20)
+// @Success      200  {object}  handlers.APIResponse{data=object{logs=array,pagination=object}}
+// @Failure      400  {object}  handlers.APIResponse "Validation error"
+// @Failure      401  {object}  handlers.APIResponse "Unauthorized"
+// @Failure      500  {object}  handlers.APIResponse "Internal server error"
+// @Router       /audit/logs [get]
+func (ah *AuditHandler) SearchLogs() gin.HandlerFunc {
+    // Implementation
+}
+```
+
+## Generating Swagger Documentation
+
+### Prerequisites
+
+Install `swag` CLI tool:
+
+```bash
+go install github.com/swaggo/swag/cmd/swag@latest
+```
+
+### Generate Documentation
+
+From the `veza-backend-api` directory:
+
+```bash
+swag init -g cmd/api/main.go
+```
+
+This will:
+1. Scan all Go files for Swagger annotations
+2. Generate `docs/docs.go`
+3. Generate `docs/swagger.json`
+4. Generate `docs/swagger.yaml`
+
+### Verify Generation
+
+1. Start the server
+2. Visit `http://localhost:8080/swagger/index.html`
+3. Verify all endpoints are documented
+4. Test endpoint documentation accuracy
+
+## Standard Response Formats
+
+### Success Response
+
+All success responses use the `APIResponse` envelope:
+
+```go
+// @Success      200  {object}  handlers.APIResponse{data=object{field=type}}
+```
+
+### Error Response
+
+All error responses use the `APIResponse` envelope with error object:
+
+```go
+// @Failure      400  {object}  handlers.APIResponse "Validation error"
+// @Failure      401  {object}  handlers.APIResponse "Unauthorized"
+// @Failure      404  {object}  handlers.APIResponse "Not found"
+// @Failure      500  {object}  handlers.APIResponse "Internal server error"
+```
+
+### Paginated Response
+
+For paginated endpoints:
+
+```go
+// @Success      200  {object}  handlers.APIResponse{data=object{items=array,pagination=object}}
+```
+
+## Handlers Needing Annotations
+
+The following handlers should have Swagger annotations added:
+
+1. **Audit Handlers** (`internal/handlers/audit.go`):
+   - `SearchLogs` - ✅ Should add annotations
+   - `GetStats` - ✅ Should add annotations
+   - `GetSuspiciousActivity` - ✅ Should add annotations
+
+2. **Webhook Handlers** (`internal/handlers/webhook_handlers.go`):
+   - `RegisterWebhook` - ✅ Should add annotations
+   - `ListWebhooks` - ✅ Should add annotations
+   - `DeleteWebhook` - ✅ Should add annotations
+   - `GetWebhookStats` - ✅ Should add annotations
+   - `TestWebhook` - ✅ Should add annotations
+   - `RegenerateAPIKey` - ✅ Should add annotations
+
+3. **Comment Handlers** (`internal/handlers/comment_handler.go`):
+   - `GetComments` - ✅ Should add annotations
+   - `CreateComment` - ✅ Should add annotations
+   - `DeleteComment` - ✅ Should add annotations
+
+4. **Other Handlers**:
+   - Check all handlers in `internal/handlers/` for missing annotations
+   - Add annotations when creating new handlers
+
+## Maintenance Workflow
+
+### When Adding a New Endpoint
+
+1. **Add Swagger annotations** to the handler function
+2. **Follow the standard format** (see examples above)
+3. **Include all parameters** (path, query, body)
+4. **Document all responses** (success and error cases)
+5. **Regenerate documentation**: `swag init -g cmd/api/main.go`
+6. **Verify in Swagger UI**: Check `/swagger/index.html`
+7. **Commit changes**: Include both handler and generated docs
+
+### When Modifying an Endpoint
+
+1. **Update Swagger annotations** if parameters or responses change
+2. **Regenerate documentation**: `swag init -g cmd/api/main.go`
+3. **Verify changes** in Swagger UI
+4. **Update related documentation** if needed
+
+### Regular Maintenance
+
+1. **Review Swagger UI** periodically to ensure all endpoints are documented
+2. **Check for outdated annotations** when refactoring handlers
+3. **Keep annotations in sync** with actual implementation
+4. **Update version** in `main.go` when making breaking changes
+
+## CI/CD Integration
+
+### Pre-commit Hook (Recommended)
+
+Add a pre-commit hook to ensure documentation is up to date:
+
+```bash
+#!/bin/bash
+# .git/hooks/pre-commit
+
+cd veza-backend-api
+swag init -g cmd/api/main.go
+git add docs/
+```
+
+### CI Check (Recommended)
+
+Add a CI step to verify documentation:
+
+```yaml
+- name: Generate Swagger docs
+  run: |
+    cd veza-backend-api
+    go install github.com/swaggo/swag/cmd/swag@latest
+    swag init -g cmd/api/main.go
+    
+- name: Check if docs changed
+  run: |
+    git diff --exit-code docs/ || (echo "Swagger docs out of sync!" && exit 1)
+```
+
+## Best Practices
+
+1. **Always add annotations** when creating new handlers
+2. **Keep annotations accurate** - they should match the actual implementation
+3. **Use descriptive summaries** - clear, concise descriptions
+4. **Document all parameters** - path, query, body parameters
+5. **Document all responses** - success and error cases
+6. **Use consistent tags** - group related endpoints
+7. **Include examples** in descriptions when helpful
+8. **Regenerate after changes** - always regenerate docs after modifying annotations
+
+## Troubleshooting
+
+### Swagger UI Not Loading
+
+1. Check that `docs/docs.go` exists and is valid
+2. Verify route is registered: `router.GET("/swagger/*any", ...)`
+3. Check imports in `main.go`: `_ "veza-backend-api/docs"`
+4. Restart the server
+
+### Missing Endpoints in Swagger
+
+1. Verify annotations are present on handler functions
+2. Check annotation syntax (no typos)
+3. Regenerate: `swag init -g cmd/api/main.go`
+4. Check that handler is registered in router
+
+### Incorrect Documentation
+
+1. Verify annotations match actual implementation
+2. Check parameter types and names
+3. Verify response structures
+4. Regenerate documentation
+
+## Files Modified
+
+- Created: `OPENAPI_MAINTENANCE_GUIDE.md` (this document)
+- Updated: Added Swagger annotations to key handlers
+
+## Next Steps
+
+1. ✅ Document Swagger maintenance process
+2. ⏳ Add annotations to remaining handlers
+3. ⏳ Set up CI/CD checks for documentation
+4. ⏳ Create pre-commit hook for auto-generation
+5. ⏳ Regular review of Swagger UI for completeness
