Email Intake

A system mailbox can be configured with the Convert to Draft Order email processing type so that purchase orders sent by email are recognized automatically. The mailbox process sends one message per attachment to the oro_order_recognition.recognize_order.email_attachment topic described in Asynchronous Processing. This page describes the parts that implement the intake and shows how to change the mailbox rules. All examples use the Acme\Bundle\SmartOrderBundle namespace.

Mailbox Process

Three parts implement the email intake:

Oro\Bundle\OrderRecognitionBundle\Email\OrderMailboxProcessProvider: Tagged oro_email.mailbox_process with type: order. It provides the label of the process type, the settings entity, the settings form type, and the name of the process definition, convert_mailbox_email_to_order.
Oro\Bundle\OrderRecognitionBundle\Entity\OrderMailboxProcessSettings: Extends Oro\Bundle\EmailBundle\Entity\MailboxProcessSettings with one field, owner (a back-office User, required). The owner becomes the owner of every draft order created from the mailbox and receives the notifications. The form type is Oro\Bundle\OrderRecognitionBundle\Form\Type\OrderMailboxProcessSettingsType.
convert_mailbox_email_to_order: A process definition in Resources/config/oro/processes.yml that runs on Oro\Bundle\EmailBundle\Entity\EmailBody with execution order 150. It is listed under the oro_order_recognition feature and is disabled together with it.

The process performs the following steps for every synchronized email body:

Finds the Email of the body and all mailboxes with the order process type that received it (@find_mailboxes).
For each mailbox, continues only when the email was sent after the mailbox settings were last updated (email.sentAt greater than mailbox.updatedAt) and the email has attachments.
Finds a CustomerUser whose email equals the sender address and who is not a guest. When one exists, its ID is passed as customerUserId; otherwise the message is sent without a customer user, and the pipeline resolves the customer user from the recognized data.
For every attachment without an embeddedContentId (inline images such as logos and signatures are skipped), sends the email attachment topic with emailAttachmentId, ownerId taken from the mailbox process settings, customerUserId, and the Email as an activity, so the email is linked to the draft order.

Note

Guest customer users are never matched, and emails that were received before the mailbox settings were last saved are ignored. Every non-inline attachment produces its own recognition message and, when the recognition succeeds, its own draft order.

Change the Mailbox Rules

Process definitions with the same name replace each other: the configuration provider keeps the definition from the last processes.yml it reads, so an override restates the whole convert_mailbox_email_to_order definition from Resources/config/oro/processes.yml of the bundle and changes only the places it needs. Place the file in a bundle loaded after OroOrderRecognitionBundle and reload the definitions with php bin/console oro:process:configuration:load.

The following fragments show the two changes of an override that processes only PDF attachments and suppresses the notifications. The first fragment adds a condition on the attachment content type to the @tree conditions of the attachment traversal:

Acme/Bundle/SmartOrderBundle/Resources/config/oro/processes.yml

- '@tree':
    conditions:
        '@and':
            - '@empty': $.attachment.embeddedContentId
            - '@eq': [ $.attachment.contentType, 'application/pdf' ]

The second fragment sets skipNotifications in the message body of the @call_service_method action that sends the email attachment topic:

Acme/Bundle/SmartOrderBundle/Resources/config/oro/processes.yml

- '@call_service_method':
    service: oro_message_queue.message_producer
    method: send
    method_parameters:
        - 'oro_order_recognition.recognize_order.email_attachment'
        - {
            emailAttachmentId: $.attachment.id,
            ownerId: $.mailbox.processSettings.owner.id,
            customerUserId: $.customerUserId,
            skipNotifications: true,
            activities: [
                { 'class': 'Oro\Bundle\EmailBundle\Entity\Email', 'id': $.email.id }
            ]
        }

To route the attachments to a custom intake topic instead, replace the topic name and the message body in the @call_service_method action with the ones of the custom topic.
