# Resend
[](https://livebook.dev/run?url=https%3A%2F%2Fraw.githubusercontent.com%2Felixir-saas%2Fresend-elixir%2Fmain%2Fresend_elixir.livemd)
API client for [Resend](https://resend.com/), the new email API for developers.
## API
* [`Resend.Emails`](https://hexdocs.pm/resend/Resend.Emails.html)
* [`Resend.Domains`](https://hexdocs.pm/resend/Resend.Domains.html)
* [`Resend.ApiKeys`](https://hexdocs.pm/resend/Resend.ApiKeys.html)
## Installation
Install by adding `resend` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:resend, "~> 0.4.4"}
]
end
```
## Getting Started
Send your first email in two steps:
```ex
# Configure your Resend API key
config :resend, Resend.Client, api_key: "re_123456789"
```
```ex
# Send an email
Resend.Emails.send(%{
to: "me@example.com",
from: "myapp@example.com",
subject: "Hello!",
text: "👋🏻"
})
```
Elixir script example:
```ex
# Save this file as `resend.exs`, run it with `elixir resend.exs`
Mix.install([
{:resend, "~> 0.4.1"}
])
# Replace with your API key
client = Resend.client(api_key: "re_123456789")
# Replace `:to` and `:from` with valid emails
Resend.Emails.send(client, %{
to: "me@example.com",
from: "myapp@example.com",
subject: "Hello!",
text: "👋🏻"
})
```

## Swoosh Adapter
This library includes a Swoosh adapter to make using Resend with a new Phoenix project as easy as
possible. All you have to do is configure your Mailer:
```ex
config :my_app, MyApp.Mailer,
adapter: Resend.Swoosh.Adapter,
api_key: "re_123456789"
```

## Testing
By default, calls to Resend are mocked in tests. To send live emails while running
the test suite, set the following environment variables:
```sh
RESEND_KEY="re_123456789" \
RECIPIENT_EMAIL="<to_email>" \
SENDER_EMAIL="<from_email>" \
SENT_EMAIL_ID="<existing_email_id>" \
mix test
```
