An adapter that sends email using Gmail api

For reference: Gmail API docs

Dependency

Gmail adapter requires Mail dependency to format message as RFC 2822 message.

{:mail, ">= 0.0.0"}

Because Mail library removes Bcc headers, they are being added after email is rendered, in adapter code.

Example

# config/congig.exs
config :sample, Sample.Mailer
  adapter: Swoosh.Adapters.Gmail,
  access_token: {:system, GMAIL_API_ACCESS_TOKEN}

# To deal with token refresh, it could be a better idea to pass the access token
# in via deliver config explicitly, if you don't update the environment variable
# periodically. e.g.
MyMailer.deliver(my_email, access_token: my_access_token)

# lib/sample/mailer.ex
defmodule Sample.Mailer do
  use Swoosh.Mailer, otp_app: :sample
end

Required config parameters

• :access_token valid OAuth2 access token Required scopes:
  • gmail.compose See https://developers.google.com/oauthplayground when developing
