# 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
