# Platform Hub API Reference

What can and cannot be managed via the Octopus Deploy API versus the UI.

## API-Manageable Resources

These can be created, read, updated, and deleted via the REST API:

| Resource | Endpoint | Notes |
|----------|----------|-------|
| Spaces | `POST /api/spaces` | Requires `SpaceManagersTeamMembers` |
| Environments | `POST /api/{SpaceId}/environments` | |
| Lifecycles | `POST /api/{SpaceId}/lifecycles` | Include phase definitions |
| Project Groups | `POST /api/{SpaceId}/projectgroups` | |
| Docker Feeds | `POST /api/{SpaceId}/feeds` | `FeedType: "Docker"` |
| Step Templates | `POST /api/{SpaceId}/actiontemplates` | Space-scoped |
| Projects | `POST /api/{SpaceId}/projects` | |
| Channels | `POST /api/{SpaceId}/channels` | With lifecycle assignment |
| Releases | `POST /api/{SpaceId}/releases` | With channel and package selection |
| Runbooks | `POST /api/{SpaceId}/runbooks` | |
| Deployment Processes | `GET/PUT /api/{SpaceId}/deploymentprocesses/{id}` | |
| Variables | `GET/PUT /api/{SpaceId}/variables/{id}` | |

## UI-Only Operations

These **cannot** be done via API or CLI — must use the Octopus web UI:

| Operation | Why |
|-----------|-----|
| **Publish process template** (create version) | Platform Hub feature, no API endpoint |
| **Share process template** with spaces | Platform Hub feature, no API endpoint |
| **Configure Platform Hub Git connection** | Instance-level setting |
| **Convert project to Config as Code** | `POST .../git/convert` exists but requires Git credentials interactively |

## Common API Patterns

### Authentication

All API calls require the `X-Octopus-ApiKey` header:

```bash
API_KEY=$(grep 'value:' ~/dev/claude/secrets/taniwha.octopus.app/api_key | awk '{print $2}')
curl -s -H "X-Octopus-ApiKey: $API_KEY" \
  "https://taniwha.octopus.app/api/Spaces-103/environments"
```

### Create a Space

```bash
curl -s -H "X-Octopus-ApiKey: $API_KEY" \
  -H "Content-Type: application/json" \
  -X POST "https://taniwha.octopus.app/api/spaces" \
  -d '{
    "Name": "My Space",
    "SpaceManagersTeamMembers": ["Users-21"],
    "IsDefault": false
  }'
```

Note: `SpaceManagersTeamMembers` must not be empty — at least one user or team required.

### Create Environments

```bash
for env in Development Staging Production; do
  curl -s -H "X-Octopus-ApiKey: $API_KEY" \
    -H "Content-Type: application/json" \
    -X POST "https://taniwha.octopus.app/api/$SPACE_ID/environments" \
    -d "{\"Name\": \"$env\"}"
done
```

### Create Lifecycles with Auto-Deploy Phases

```bash
# Non-Prod: Dev → Staging (auto-deploy both)
curl -s -H "X-Octopus-ApiKey: $API_KEY" \
  -H "Content-Type: application/json" \
  -X POST "https://taniwha.octopus.app/api/$SPACE_ID/lifecycles" \
  -d '{
    "Name": "Non-Prod",
    "Phases": [
      {
        "Name": "Development",
        "AutomaticDeploymentTargets": ["Environments-104"],
        "OptionalDeploymentTargets": [],
        "MinimumEnvironmentsBeforePromotion": 0,
        "IsOptionalPhase": false
      },
      {
        "Name": "Staging",
        "AutomaticDeploymentTargets": ["Environments-105"],
        "OptionalDeploymentTargets": [],
        "MinimumEnvironmentsBeforePromotion": 0,
        "IsOptionalPhase": false
      }
    ]
  }'
```

### Create Docker Feed (GHCR)

```bash
curl -s -H "X-Octopus-ApiKey: $API_KEY" \
  -H "Content-Type: application/json" \
  -X POST "https://taniwha.octopus.app/api/$SPACE_ID/feeds" \
  -d '{
    "FeedType": "Docker",
    "Name": "GHCR Non-Prod",
    "FeedUri": "https://ghcr.io"
  }'
```

### Create Step Template (Action Template)

```bash
curl -s -H "X-Octopus-ApiKey: $API_KEY" \
  -H "Content-Type: application/json" \
  -X POST "https://taniwha.octopus.app/api/$SPACE_ID/actiontemplates" \
  -d '{
    "Name": "Run Unit Tests",
    "Description": "Language-specific unit test suite",
    "ActionType": "Octopus.Script",
    "Properties": {
      "Octopus.Action.Script.ScriptSource": "Inline",
      "Octopus.Action.Script.Syntax": "PowerShell",
      "Octopus.Action.Script.ScriptBody": "Write-Host \"Running tests...\""
    },
    "Parameters": [
      {
        "Name": "Language",
        "Label": "Programming Language",
        "DefaultValue": "go",
        "DisplaySettings": {
          "Octopus.ControlType": "SingleLineText"
        }
      }
    ]
  }'
```

### Create Release via API (CI-driven)

```bash
curl -s -X POST \
  -H "X-Octopus-ApiKey: $API_KEY" \
  -H "Content-Type: application/json" \
  "https://taniwha.octopus.app/api/$SPACE_ID/releases" \
  -d '{
    "ProjectId": "Projects-XXX",
    "ChannelId": "Channels-XXX",
    "Version": "1.2.3+202603251530",
    "SelectedPackages": [{
      "ActionName": "Deploy Non-Prod Image",
      "PackageReferenceName": "service-image",
      "Version": "1.2.3+202603251530"
    }]
  }'
```

## Idempotent Script Pattern

For automation scripts that may be re-run:

```bash
# Check if resource exists before creating
existing=$(curl -s -H "X-Octopus-ApiKey: $API_KEY" \
  "https://taniwha.octopus.app/api/$SPACE_ID/projectgroups?take=100" \
  | python3 -c "
import sys, json
name = sys.argv[1]
for item in json.load(sys.stdin).get('Items', []):
    if item['Name'] == name:
        print(item['Id'])
        break
" "Marketplace" 2>/dev/null || echo "")

if [[ -n "$existing" ]]; then
  echo "Already exists: $existing"
else
  # Create it
  curl -s -X POST ...
fi
```
