# Resend CLI

> Operate the Resend platform from the terminal — send emails (including React Email .tsx templates via --react-email), manage domains, contacts, broadcasts, templates, webhooks, API keys, logs, automations, and events via the `resend` CLI. Use when the user wants to run Resend commands in the shell, scripts, or CI/CD pipelines, or send/preview React Email templates. Always load this skill before running `resend` commands — it contains the non-interactive flag contract and gotchas that prevent silent failures.

# Resend CLI

## This repository (Asymmetric-al/core)

These repo-owned sections are intentionally kept on top of the vendored Resend
CLI skill. If upstream refreshes replace this file, reconcile this overlay
before running `bun run skills:sync`. App-level Resend integration lives in
`docs/guides/features/resend-integration.md`; this skill is only for the
terminal CLI, shell scripts, and CI automation.

### Triggers

- Running, scripting, installing, or troubleshooting the `resend` CLI.
- Resend CLI work in local shells, CI/CD, automations, or non-interactive agent runs.
- Sending or previewing React Email templates through CLI flags.

### Workflow

1. Confirm the task is CLI work; for product email routes, SDK, webhooks, or inbound handling, use `docs/guides/features/resend-integration.md` instead.
2. Check `resend --version` before invoking CLI commands.
3. Confirm required environment variables are available without printing secret values.
4. Use non-interactive flags and JSON-safe output patterns from this skill.
5. Verify the command result and capture sanitized IDs/status only.

### Checklist

- [ ] Confirmed the task belongs to Resend CLI rather than app integration.
- [ ] Verified the `resend` binary and auth/env prerequisites.
- [ ] Avoided printing API keys, tokens, or full secret values.
- [ ] Used non-interactive flags suitable for agents/CI.
- [ ] Recorded sanitized command evidence or a clear blocker.

## Installation

Before running any `resend` commands, check whether the CLI is installed:

```bash
resend --version
```

If the command is not found, install it using one of the methods below:

**cURL (macOS / Linux):**

```bash
curl -fsSL https://resend.com/install.sh | bash
```

**Homebrew (macOS / Linux):**

```bash
brew install resend/cli/resend
```

**Node.js:**

```bash
npm install -g resend-cli
```

**PowerShell (Windows):**

```powershell
irm https://resend.com/install.ps1 | iex
```

After installing, verify:

```bash
resend --version
```

## Agent Protocol

The CLI auto-detects non-TTY environments and outputs JSON — no `--json` flag needed.

**Rules for agents:**

- Supply ALL required flags. The CLI will NOT prompt when stdin is not a TTY.
- Pass `--quiet` (or `-q`) to suppress spinners and status messages.
- Exit `0` = success, `1` = error.
- Error JSON goes to stderr, success JSON goes to stdout:
  ```json
  { "error": { "message": "...", "code": "..." } }
  ```
- Use `--api-key` or `RESEND_API_KEY` env var. Never rely on interactive login.
- All `delete`/`rm` commands require `--yes` in non-interactive mode.

## Authentication

Auth resolves: `--api-key` flag > `RESEND_API_KEY` env > config file (`resend login --key`). Use `--profile` or `RESEND_PROFILE` for multi-profile.

## Global Flags

| Flag                   | Description                                 |
| ---------------------- | ------------------------------------------- |
| `--api-key <key>`      | Override API key for this invocation        |
| `-p, --profile <name>` | Select stored profile                       |
| `--json`               | Force JSON output (auto in non-TTY)         |
| `-q, --quiet`          | Suppress spinners/status (implies `--json`) |

**Dry-run:** Only `emails send` and `broadcasts create` support `--dry-run` (payload validation before send/create). They print `{ "dryRun": true, "request": { ... } }` on stdout without calling the API. There is no `--dry-run` on `emails batch`, `broadcasts send`, or other commands yet.

## Common Mistakes

| #   | Mistake                                                                 | Fix                                                                                                                                 |
| --- | ----------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------- |
| 1   | **Forgetting `--yes` on delete commands**                               | All `delete`/`rm` subcommands require `--yes` in non-interactive mode — otherwise the CLI exits with an error                       |
| 2   | **Not saving webhook `signing_secret`**                                 | `webhooks create` shows the secret once only — it cannot be retrieved later. Capture it from command output immediately             |
| 3   | **Omitting `--quiet` in CI**                                            | Without `-q`, spinners and status text still go to stderr (not stdout). Use `-q` for JSON on stdout with no spinner noise on stderr |
| 4   | **Using `--scheduled-at` with batch**                                   | Batch sending does not support `scheduled_at` — use single `emails send` instead                                                    |
| 5   | **Expecting `domains list` to include DNS records**                     | List returns summaries only — use `domains get <id>` for the full `records[]` array                                                 |
| 6   | **Sending a dashboard-created broadcast via CLI**                       | Only API-created broadcasts can be sent with `broadcasts send` — dashboard broadcasts must be sent from the dashboard               |
| 7   | **Passing `--events` to `webhooks update` expecting additive behavior** | `--events` replaces the entire subscription list — always pass the complete set                                                     |
| 8   | **Expecting `logs list` to include request/response bodies**            | List returns summary fields only — use `logs get <id>` for full `request_body` and `response_body`                                  |

## Common Patterns

**Send an email:**

```bash
resend emails send --from "you@domain.com" --to user@example.com --subject "Hello" --text "Body"
```

**Send a React Email template (.tsx):**

```bash
resend emails send --from "you@domain.com" --to user@example.com --subject "Welcome" --react-email ./emails/welcome.tsx
```

**Domain setup flow:**

```bash
resend domains create --name example.com --region us-east-1
# Configure DNS records from output, then:
resend domains verify <domain-id>
resend domains get <domain-id>  # check status
```

**Create and send a broadcast:**

```bash
resend broadcasts create --from "news@domain.com" --subject "Update" --segment-id <id> --html "<h1>Hi</h1>" --send
```

**CI/CD (no login needed):**

```bash
RESEND_API_KEY=re_xxx resend emails send --from ... --to ... --subject ... --text ...
```

**Check environment health:**

```bash
resend doctor -q
```
