| 10 | + |
| 11 | +## ✅ Completed Features (98%) |
| 12 | + |
| 13 | +### Core CRUD Operations |
| 14 | + |
| 15 | +All basic connection operations are fully implemented: |
| 16 | + |
| 17 | +- **[`connection create`](../pkg/cmd/connection_create.go)** - Single API call with inline source/destination creation |

| 20 | +- **[`connection upsert`](../pkg/cmd/connection_upsert.go)** - Idempotent create/update with `--dry-run` support (replaces deprecated `update`) |
| 21 | +- **[`connection delete`](../pkg/cmd/connection_delete.go)** - With confirmation prompts |
| 22 | + |
| 23 | +### Lifecycle Management |
| 24 | + |
| 25 | +Complete state management across all connection states: |
| 26 | + |
| 27 | +- **[`connection enable`](../pkg/cmd/connection_enable.go)** - Enable disabled connections |
| 28 | +- **[`connection disable`](../pkg/cmd/connection_disable.go)** - Disable active connections |

| 32 | +- **[`connection unarchive`](../pkg/cmd/connection_unarchive.go)** - Restore from archive |
| 33 | + |
| 34 | +### Source Authentication (Commit 8acf8d3) |
| 35 | + |
| 36 | +Full authentication support for 96+ source types with universal flags covering 80% of use cases and JSON fallback for complex scenarios: |
| 37 | + |
| 38 | +**Authentication Flags:** |
| 39 | +```bash |
| 40 | +# Webhook secret verification (STRIPE, GITHUB, SHOPIFY, etc.) |
| 41 | +--source-webhook-secret <secret> |
| 42 | + |
| 43 | +# API key authentication (GITLAB, BITBUCKET, etc.) |
| 44 | +--source-api-key <key> |
| 45 | + |
| 46 | +# Basic authentication |
| 47 | +--source-basic-auth-user <user> |
| 48 | +--source-basic-auth-pass <password> |
| 49 | + |
| 50 | +# HMAC signature verification |
| 51 | +--source-hmac-secret <secret> |
| 52 | +--source-hmac-algo <algorithm> |
| 53 | + |
| 54 | +# JSON fallback for complex configurations |
| 55 | +--source-config <json-string> |
| 56 | +--source-config-file <path-to-json> |
| 57 | +``` |
| 58 | + |
| 59 | +**Type-Specific Validation:** Dynamic validation ensures only valid authentication methods are used for each source type (e.g., STRIPE requires webhook-secret, GITLAB requires api-key). |
| 60 | + |
| 61 | +### Destination Authentication (Commit 8acf8d3) |
| 62 | + |
| 63 | +Complete authentication support for HTTP, CLI, and Mock API destinations: |
| 64 | + |
| 65 | +**Authentication Flags:** |
| 66 | +```bash |
| 67 | +# Bearer token authentication |
| 68 | +--destination-bearer-token <token> |
| 69 | + |
| 70 | +# Basic authentication |
| 71 | +--destination-basic-auth-user <user> |
| 72 | +--destination-basic-auth-pass <password> |
| 73 | + |
| 74 | +# API key authentication |
| 75 | +--destination-api-key <key> |
| 76 | +--destination-api-key-name <header-name> # Defaults to "x-api-key" |
| 77 | + |
| 78 | +# Custom headers (JSON) |
| 79 | +--destination-custom-headers <json-string> |
| 80 | +--destination-custom-headers-file <path-to-json> |
| 81 | + |
| 82 | +# OAuth2 configuration |
| 83 | +--destination-oauth2-client-id <id> |
| 84 | +--destination-oauth2-client-secret <secret> |
| 85 | +--destination-oauth2-token-url <url> |
| 86 | +--destination-oauth2-scopes <scope1,scope2> |
| 87 | + |
| 88 | +# JSON fallback for complex configurations |
| 89 | +--destination-config <json-string> |
| 90 | +--destination-config-file <path-to-json> |
| 91 | +``` |
| 92 | + |
| 93 | +### Rule Configuration (Commit 8acf8d3) |
| 94 | + |
| 95 | +All 5 rule types fully implemented with ordered execution support: |
| 96 | + |
| 97 | +**1. Retry Rules:** |
| 98 | +```bash |
| 99 | +--rule-retry-strategy <linear|exponential> |
| 100 | +--rule-retry-count <number> |
| 101 | +--rule-retry-interval <milliseconds> |
| 102 | +--rule-retry-response-status-codes <"500-599,!401,404"> |
| 103 | +``` |
| 104 | + |
| 105 | +**2. Filter Rules:** |
| 106 | +```bash |
| 107 | +--rule-filter-body <jq-expression> |
| 108 | +--rule-filter-headers <jq-expression> |
| 109 | +--rule-filter-query <jq-expression> |
| 110 | +--rule-filter-path <jq-expression> |
| 111 | +``` |
| 112 | + |
| 113 | +**3. Transform Rules:** |
| 114 | +```bash |
| 115 | +--rule-transform-name <transformation-name-or-id> |
| 116 | +--rule-transform-code <javascript-code> |
| 117 | +--rule-transform-env <json-env-vars> |
| 118 | +``` |
| 119 | + |
| 120 | +**4. Delay Rules:** |
| 121 | +```bash |
| 122 | +--rule-delay-delay <milliseconds> |
| 123 | +``` |
| 124 | + |
| 125 | +**5. Deduplicate Rules:** |
| 126 | +```bash |
| 127 | +--rule-deduplicate-window <milliseconds> |
| 128 | +--rule-deduplicate-include-fields <field1,field2> |
| 129 | +--rule-deduplicate-exclude-fields <field1,field2> |
| 130 | +``` |
| 131 | + |
| 132 | +**Rule Ordering:** Rules are executed in the order flags appear on the command line. See [`connection-rules-cli-design.md`](./connection-rules-cli-design.md) for complete specification. |
| 133 | + |
| 134 | +**JSON Fallback:** |
| 135 | +```bash |
| 136 | +--rules <json-array> |
| 137 | +--rules-file <path-to-json> |
| 138 | +``` |
| 139 | + |
| 140 | +### Rate Limiting |
| 141 | + |
| 142 | +Full rate limiting configuration for destinations: |
| 143 | + |
| 144 | +```bash |
| 145 | +--destination-rate-limit <requests> |
| 146 | +--destination-rate-limit-period <seconds|minutes|hours> |
| 147 | +``` |
| 148 | + |
| 149 | +### Idempotent Operations (Commit 8ab6cac) |
| 150 | + |
| 151 | +The [`connection upsert`](../pkg/cmd/connection_upsert.go) command provides declarative, idempotent connection management: |
| 152 | + |
| 153 | +**Features:** |
| 154 | +- Creates connection if it doesn't exist (by name) |
| 155 | +- Updates connection if it exists |
| 156 | +- `--dry-run` flag for safe preview of changes |
| 157 | +- Replaces deprecated `connection update` command |
| 158 | +- Ideal for infrastructure-as-code workflows |
| 159 | + |
| 160 | +**Example:** |
| 161 | +```bash |
| 162 | +# Preview changes before applying |
| 163 | +hookdeck connection upsert my-connection \ |
| 164 | + --source-type STRIPE \ |
| 165 | + --destination-url https://api.example.com \ |
| 166 | + --rule-retry-strategy exponential \ |
| 167 | + --dry-run |
| 168 | + |
| 169 | +# Apply changes |
| 170 | +hookdeck connection upsert my-connection \ |
| 171 | + --source-type STRIPE \ |
| 172 | + --destination-url https://api.example.com \ |
| 173 | + --rule-retry-strategy exponential |
| 174 | +``` |
| 175 | + |
| 176 | +## 📋 Optional Enhancements (Low Priority) |
| 177 | + |
| 178 | +The following features would add convenience but are not critical for production use: |
| 179 | + |
| 180 | +### Bulk Operations (2% remaining) |
| 181 | +- `connection bulk-enable` - Enable multiple connections at once |
| 182 | +- `connection bulk-disable` - Disable multiple connections at once |
| 183 | +- `connection bulk-delete` - Delete multiple connections with confirmation |
| 184 | +- `connection bulk-archive` - Archive multiple connections |
| 185 | + |
| 186 | +**Use Case:** Managing large numbers of connections in batch operations. |
| 187 | + |
| 188 | +**Priority:** Low - users can script individual commands or use the API directly for bulk operations. |
| 189 | + |
| 190 | +### Connection Count |
| 191 | +- `connection count` - Display total number of connections with optional filters |
| 192 | + |
| 193 | +**Use Case:** Quick overview of connection inventory. |
| 194 | + |
| 195 | +**Priority:** Low - `connection list` already provides this information. |
| 196 | + |
| 197 | +### Connection Cloning |
| 198 | +- `connection clone <source-connection> <new-name>` - Duplicate a connection with a new name |
| 199 | + |
| 200 | +**Use Case:** Creating similar connections quickly. |
| 201 | + |
| 202 | +**Priority:** Low - users can achieve this by copying command-line flags or using JSON export. |
| 203 | + |
| 204 | +## Key Design Decisions |
| 205 | + |
| 206 | +### 1. Universal Flag Pattern with Type-Driven Validation |
| 207 | + |
| 208 | +**Decision:** Expose all possible flags for a resource type, but validate based on the `--type` parameter. |
| 209 | + |
| 210 | +**Rationale:** |
| 211 | +- Provides clear, discoverable CLI interface |
| 212 | +- Maintains consistent flag naming across commands |
| 213 | +- Enables helpful type-specific error messages |
| 214 | +- Avoids complex dynamic help text generation |
| 215 | + |
| 216 | +**Implementation:** See [`AGENTS.md`](../AGENTS.md) sections 2-3 for complete conversion patterns. |
| 217 | + |
| 218 | +### 2. JSON Fallback for Complex Configurations |
| 219 | + |
| 220 | +**Decision:** Provide JSON config flags (`--source-config`, `--destination-config`, `--rules`) as an escape hatch for complex scenarios. |
| 221 | + |
| 222 | +**Rationale:** |
| 223 | +- Covers 100% of API capabilities |
| 224 | +- Supports infrastructure-as-code workflows |
| 225 | +- Handles edge cases without CLI bloat |
| 226 | +- Natural path for migrating from API to CLI |
| 227 | + |
| 228 | +### 3. Rule Ordering via Flag Position |
| 229 | + |
| 230 | +**Decision:** Determine rule execution order by the position of flags on the command line. |
| 231 | + |
| 232 | +**Rationale:** |
| 233 | +- Intuitive and predictable behavior |
| 234 | +- Aligns with natural reading order (left to right) |
| 235 | +- No need for explicit ordering parameters |
| 236 | +- See [`connection-rules-cli-design.md`](./connection-rules-cli-design.md) for full specification |
| 237 | + |
| 238 | +### 4. Idempotent Upsert over Update |
| 239 | + |
| 240 | +**Decision:** Replace `connection update` with `connection upsert` and add `--dry-run` support. |
| 241 | + |
| 242 | +**Rationale:** |
| 243 | +- Idempotent operations are safer and more predictable |
| 244 | +- Declarative approach better for infrastructure-as-code |
| 245 | +- Dry-run enables preview-before-apply workflow |
| 246 | +- Single command for both create and update scenarios |
| 247 | +- See [`connection-upsert-design.md`](./connection-upsert-design.md) for full specification |
| 248 | + |
| 249 | +### 5. Single API Call with Inline Creation |
| 250 | + |
| 251 | +**Decision:** Use single `POST /connections` API call with inline source/destination creation. |
| 252 | + |
| 253 | +**Rationale:** |
| 254 | +- Atomic operation reduces error scenarios |
| 255 | +- Aligns with API design intent |
| 256 | +- Eliminates orphaned resources from failed operations |
| 257 | +- Improves performance (1 API call vs 3) |
| 258 | + |

| 281 | + |
| 282 | +## Architecture Patterns |
| 283 | + |
| 284 | +### Flag Naming Convention |
| 285 | + |
| 286 | +All flags follow consistent patterns from [`AGENTS.md`](../AGENTS.md): |
| 287 | + |
| 288 | +- **Resource identifiers:** `--name` for human-readable names |
| 289 | +- **Type parameters:** |
| 290 | + - Individual resources: `--type` |
| 291 | + - Connection creation: `--source-type`, `--destination-type` (prefixed to avoid ambiguity) |
| 292 | +- **Authentication:** Prefixed by resource (`--source-webhook-secret`, `--destination-bearer-token`) |
| 293 | +- **Collections:** Comma-separated values (`--connections "a,b,c"`) |
| 294 | +- **Booleans:** Presence flags (`--dry-run`, `--force`) |
| 295 | + |
| 296 | +### Validation Pattern |
| 297 | + |
| 298 | +Progressive validation in `PreRunE`: |
| 299 | +1. **Flag parsing validation** - Correct types |
| 300 | +2. **Type-specific validation** - Based on `--type` parameter |
| 301 | +3. **Cross-parameter validation** - Relationships between parameters |
| 302 | +4. **API schema validation** - Final validation by API |
| 303 | + |

| 312 | +## Summary |
| 313 | + |
| 314 | +Connection management is feature-complete and production-ready at 98%. All essential operations, authentication methods, rule types, and lifecycle management are fully implemented. The remaining 2% consists of convenience features (bulk operations, count, cloning) that can be added based on user feedback but are not blockers for production use. |
