description	Configuring HTTP API domain deployments and security schemes in golem.yaml. Use when the user asks to deploy agents to a domain, configure API domains, set up authentication/security schemes (OIDC), or manage the httpApi section of the application manifest.

Configuring HTTP API Domain Deployments

Overview

After adding HTTP mounts and endpoints to agents in code, you must configure a domain deployment in golem.yaml so Golem knows which agents to expose and on which domain. This skill covers the httpApi manifest section, security scheme setup, and the auto-generated OpenAPI specification.

Adding a Domain Deployment

Add an httpApi section to the root golem.yaml:

httpApi:
  deployments:
    local:
    - domain: my-app.localhost:9006
      agents:
        TaskAgent: {}
        UserAgent: {}

Structure

• httpApi.deployments is a map keyed by environment name (e.g., local, staging, prod)
• Each environment contains a list of deployment objects
• Each deployment has:
  • domain: the (sub)domain to bind to (e.g., my-app.localhost:9006 for local development)
  • agents: a map of agent type names (PascalCase) to their deployment options
  • webhookUrl (optional): base URL for webhook callbacks

Agent Options

Each agent entry accepts these optional fields:

agents:
  TaskAgent: {}                          # Default — no auth, no test header
  SecureAgent:
    securityScheme: my-oidc              # Reference a security scheme by name
  DevAgent:
    testSessionHeaderName: X-Test-Auth   # Use a test header for development

• securityScheme: name of a pre-configured security scheme (see below) — use this when the agent has auth: true
• testSessionHeaderName: header name for test/development authentication — provides a simple way to pass identity without a real OIDC flow
• Only one of securityScheme or testSessionHeaderName can be set per agent

Security Schemes

Security schemes define OIDC authentication providers. They are managed via the Golem CLI:

Creating a Security Scheme

golem api security-scheme create my-oidc \
  --provider-type google \
  --client-id "YOUR_CLIENT_ID" \
  --client-secret "YOUR_CLIENT_SECRET" \
  --redirect-url "http://localhost:9006/auth/callback" \
  --scope openid --scope email --scope profile

Supported Providers

Provider	--provider-type value
Google	google
Facebook	facebook
Microsoft	microsoft
GitLab	gitlab
Custom OIDC	custom (requires --issuer-url)

For a custom OIDC provider:

golem api security-scheme create my-custom-oidc \
  --provider-type custom \
  --issuer-url "https://auth.example.com" \
  --client-id "YOUR_CLIENT_ID" \
  --client-secret "YOUR_CLIENT_SECRET" \
  --redirect-url "https://app.example.com/auth/callback" \
  --scope openid

Managing Security Schemes

golem api security-scheme get my-oidc           # View details
golem api security-scheme update my-oidc ...     # Update fields
golem api security-scheme delete my-oidc         # Delete

Referencing in golem.yaml

After creating a security scheme, reference it by name in the agent deployment options:

httpApi:
  deployments:
    local:
    - domain: my-app.localhost:9006
      agents:
        SecureAgent:
          securityScheme: my-oidc

This enables OIDC authentication for all endpoints on SecureAgent that have auth: true set in their code-level annotations.

Test Session Header (Development)

For local development without a real OIDC provider, use a test session header:

httpApi:
  deployments:
    local:
    - domain: my-app.localhost:9006
      agents:
        SecureAgent:
          testSessionHeaderName: X-Test-Auth

Then pass identity in requests. The header value must be a JSON object representing an OIDC session. All fields have defaults, so only subject is needed to identify the caller:

curl -H 'X-Test-Auth: {"subject":"test-user-id"}' http://my-app.localhost:9006/secure/agent1/data

Available fields (all optional, with defaults):

Field	Type	Default
subject	string	"test-user"
issuer	string (URL)	"http://test-idp.com"
email	string	null
name	string	null
email_verified	boolean	null
given_name	string	null
family_name	string	null
picture	string (URL)	null
preferred_username	string	null
scopes	array of strings	["openid"]
issued_at	ISO 8601 datetime	current time
expires_at	ISO 8601 datetime	current time + 8 hours

⚠️ Important: The header value must be valid JSON — a plain string like "user1" will be rejected with a 400 error.

Multi-Environment Deployments

Define different domains and security configurations per environment:

httpApi:
  deployments:
    local:
    - domain: my-app.localhost:9006
      agents:
        TaskAgent: {}
        SecureAgent:
          testSessionHeaderName: X-Test-Auth
    prod:
    - domain: api.myapp.com
      agents:
        TaskAgent: {}
        SecureAgent:
          securityScheme: prod-google-oidc

Webhook URL

If agents use webhooks, configure the base URL:

httpApi:
  deployments:
    local:
    - domain: my-app.localhost:9006
      webhookUrl: http://my-app.localhost:9006
      agents:
        WebhookAgent: {}

The webhookUrl is combined with the agent's webhookSuffix (defined in code) to form the full webhook callback URL.

Deploying

After configuring golem.yaml, deploy. Always use --yes to avoid interactive prompts:

golem deploy --yes                     # Deploy all components and HTTP API
golem deploy --yes --reset             # Deploy and delete all previously created agents
golem deploy --yes --try-update-agents # Deploy and update running agents

Auto-Generated OpenAPI

Golem automatically serves an OpenAPI specification at /openapi.yaml on each deployment domain:

curl http://my-app.localhost:9006/openapi.yaml

This specification includes all endpoints from all agents deployed to that domain, with proper path parameters, request/response schemas, and CORS metadata.

Complete Example

# golem.yaml

httpApi:
  deployments:
    local:
    - domain: task-app.localhost:9006
      webhookUrl: http://task-app.localhost:9006
      agents:
        TaskAgent: {}
        AdminAgent:
          testSessionHeaderName: X-Admin-Auth
    prod:
    - domain: api.taskapp.com
      agents:
        TaskAgent: {}
        AdminAgent:
          securityScheme: google-oidc

Key Constraints

• Agent type names in golem.yaml use PascalCase (matching the class/trait name in code)
• Each agent entry can have at most one of securityScheme or testSessionHeaderName
• Security schemes must be created via golem api security-scheme create before they can be referenced
• The domain must be unique per environment
• After changing golem.yaml, run golem deploy --yes to apply changes
