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: type: str description: - username for logging into the SendGrid account. - Since 2.2 it is only required if api_key is not supplied. password: type: str description: - password that corresponds to the username - Since 2.2 it is only required if api_key is not supplied. from_address: type: str description: - the address in the "from" field for the email required: true to_addresses: type: list description: - a list with one or more recipient email addresses required: true subject: type: str description: - the desired subject for the email required: true api_key: type: str description: - sendgrid API key to use instead of username/password cc: type: list description: - a list of email addresses to cc bcc: type: list description: - a list of email addresses to bcc attachments: type: list description: - a list of relative or explicit paths of files you want to attach (7MB limit as per SendGrid docs) from_name: type: str description: - the name you want to appear in the from field, i.e 'John Doe' html_body: description: - whether the body is html content that should be rendered type: bool default: 'no' headers: type: dict description: -
