version_added: "2.0"
module: sendgrid
short_description: Sends an email with the SendGrid API
description:
   - "Sends an email with a SendGrid account through their API, not through
     the SMTP service."
notes:
   - "This module is non-idempotent because it sends an email through the
     external API. It is idempotent only in the case that the module fails."
   - "Like the other notification modules, this one requires an external
     dependency to work. In this case, you'll need an active SendGrid
     account."
   - "In order to use api_key, cc, bcc, attachments, from_name, html_body, headers
     you must pip install sendgrid"
   - "since 2.2 username and password are not required if you supply an api_key"
requirements:
  - sendgrid python library
options:
  username:
    description:
      - username for logging into the SendGrid account.
      - Since 2.2 it is only required if api_key is not supplied.
  password:
    description:
      - password that corresponds to the username
      - Since 2.2 it is only required if api_key is not supplied.
  from_address:
    description:
      - the address in the "from" field for the email
    required: true
  to_addresses:
    description:
      - a list with one or more recipient email addresses
    required: true
  subject:
    description:
      - the desired subject for the email
    required: true
  api_key:
    description:
      - sendgrid API key to use instead of username/password
    version_added: 2.2
  cc:
    description:
      - a list of email addresses to cc
    version_added: 2.2
  bcc:
    description:
      - a list of email addresses to bcc
    version_added: 2.2
  attachments:
    description:
      - a list of relative or explicit paths of files you want to attach (7MB limit as per SendGrid docs)
    version_added: 2.2
  from_name:
    description:
      - the name you want to appear in the from field, i.e 'John Doe'
    version_added: 2.2
  html_body:
    description:
      - whether the body is html content that should be rendered
    version_added: 2.2
    type: bool
    default: 'no'
