Update a translation in a newsletter test group

​

Update the translation of a newsletter variant in an A/B test. You can retrieve a list of test_group_ids from Get variants in a newsletter test group.

NOTE: You cannot manage content made with Design Studio with this endpoint. Use the Design Studio APIs instead. You also can't update in-app or inbox message content through the API—change it in the message editor.

Path Parameters
  • newsletter_id
    Type: integer
    required

    The identifier of a newsletter.

  • test_group_id
    Type: string
    required

    The ID of the A/B test group.

  • language
    Type: string
    required

    A language tag of a language variant. If you don't provide a language (an empty string), we'll use your default language. If the language variant does not exist, we'll return an error.

Body
application/json

    • Update the contents of an email newsletter variant. You can set the sender with from_id. If you don't provide it, the existing sender is preserved.

      • body
        Type: string

        The HTML body of the email. You cannot modify the body if you created the newsletter with Design Studio or the drag-and-drop editor.

      • body_amp
        Type: string

        AMP-enabled content for your email. If a recipient's email client doesn't support AMP, they receive your body content instead. Make sure you're set up to send AMP first.

      • body_plain
        Type: string

        By default, your workspace generates a plaintext version of your message body for each delivery. Use this key to override the default plain text body.

      • from_id
        Type: integer

        The identifier of the from address, commonly known as the "sender". Use List sender identities to find valid IDs.

      • preheader_text
        Type: string

        Also known as "preview text", this is the small block of text shown in an email inbox next to or underneath the subject line.

      • recipient
        Type: string

        The recipient address for the newsletter. By default, it's {{customer.email}}.

      • reply_to_id
        Type: integer | null

        The identifier for the reply_to address, if applicable. Use List sender identities to find valid IDs.

      • subject
        Type: string

        The subject line for an email action.
