API Normalization

What It Does

Turn Drupal into a management dashboard for external APIs—without writing code.

Import any API's OpenAPI/Swagger schema, and this module automatically creates fieldable Drupal entities for each endpoint, admin forms to manage API data, ECA-driven workflows on API events, and automatic provider failover.

Example: Import the GitLab API, and you get Drupal admin pages to create issues, manage repositories, and trigger automated workflows—no custom code required.

Who It's For

• Site builders who want to connect external services without custom code
• Agencies managing multiple client APIs from one Drupal dashboard
• DevOps teams needing API failover, monitoring, and request transformation
• AI/ML users running multiple AI providers with automatic fallback via the
  AI module

Architecture

Built on proven Drupal contrib—no reinventing the wheel:

• ECK — 7 fieldable entity types:
  api_endpoint, api_key, openapi_schema,
  import_draft, gateway_route, tenant,
  api_normalization_rule
• AI module — Tool plugin integration
  for schema import, gateway routing, and response processing
• ECA — Event-driven workflows on
  API events
• Feeds — Data import/export
  workflows with Tamper transforms
• Key — Secure API key storage
• HTTP Client Manager
  — HTTP service definitions via YAML
• OpenAPI — Schema validation via
  league/openapi-psr7-validator

Features

OpenAPI Import

• Import OpenAPI 3.0/3.1 schemas by URL, file upload, or paste
• Generates Drupal entities from API endpoints via ECK
• Schema validation with league/openapi-psr7-validator
• Import drafts allow staged review before entity creation

Multi-Provider AI Services

Works with any provider supported by the
AI module—OpenAI, Anthropic, Ollama, HuggingFace, and others. One interface, multiple providers, automatic failover.

Deep Drupal Integration

• JSON:API and REST endpoints for all imported API entities
• Views integration for API data
• ECA workflow triggers on API events
• Token support for templates
• Advanced Queue for background API processing

Submodules

• api_normalization_gateway — API gateway for request transformation
  and routing
• api_normalization_tamper — Transform AI provider responses to
  OpenAI-compatible format via Tamper plugins
• api_normalization_flowdrop — Visual workflow nodes for schema.org
  mapping, entity classification, and OpenAPI spec generation via
  FlowDrop
• api_normalization_orchestration — Exposes capabilities to external
  automation platforms (N8N, Zapier) via the Orchestration module
• api_normalization_audit — Audit logging, metrics collection, and
  performance monitoring
• api_normalization_modeler — Visual API routing flow design via the
  Modeler API

Quick Start

composer require 'drupal/api_normalization:^1.0@alpha'
  drush en api_normalization

1. Go to Configuration → Web Services → API Normalization
2. Click Import OpenAPI Schema
3. Enter an API documentation URL or upload a file
4. Select which endpoints to import
5. Done—you now have Drupal admin pages for that API
