Multilingual push requires 14 columns in the CSV file:
- title
- messageBody
- sound
- badge
- deeplinkURI
- category
- iosMediaAttachmentURL
- androidMediaAttachmentURL
- isContentAvailable
- isMutableContent
- customFields
- locale
- language
- silentPush

Please check the CSV sample by clicking the Download a sample file in the Manage Content Variants window. For more on this, refer to the multilingual push notification documentation.
- title, messageBody, sound, badge, deeplinkURI, category, iosMediaAttachmentURL, androidMediaAttachmentURL are regular push payload contents. Customers need to provide this information in a similar manner as when creating push deliveries.
- Custom Fields: use JSON format for the custom fields, e.g."{""key1"":""value1"",""key2"":""value2""}". Refer to the sample file above for an example of custom fields.
- isContentAvailable: flag for Content Available check, value 1 implies true, value 0 implies false. The default value is 0. If customer leaves this column blank, the value will be considered 0.
- isMutableContent: flag for Mutable Content, value 1 implies true, value 0 implies false. The default value is 0. If customer leaves this column blank, the value will be considered 0.
- locale: locale is the field for language variants, e.g. "en_us" for US-English and "fr_fr" for France-French.
- language: name of the language which is associated with the locale. For example, if locale is "en_us", the name of the language should be " English-United States".
- silentPush: flag for the push notification type. If it is a regular push notification, the value should be 0. If it is a silent push, the value should be 1. The default value is 0. If customer leaves this column blank, the value will be considered 0
- Name of each column is fixed. You should include the name of each column in the CSV file, if you don't use any columns for the content, leave it blank.
- "locale" and "language" columns are mandatory and value is unique for each row. A blank value for this column will result in a failure of the file upload.
- Order of columns matters. The order of the columns in the uploaded file needs to follow the same format as the sample file.
- Since this is a CSV (stands for Comma-Separated Values) file, any column content which includes comma (,) has to be quoted. For example, "Hello, Tom!"
- UTF-8 encoding is necessary for international characters.
- If you generate the file by plain text, separate each column by ","
- This format works for both iOS and Android push.
When you want to use personalization fields, you should include <span> tag in the file. Refer to the following example:
- To insert "firstName" personalization field in messageBody, the message needs to be " Hello <span class="nl-dce-field nl-dce-done" data-nl-expr="/context/profile/firstName">First name</span>, this is message".
- "firstName" field is represented by "<span class="nl-dce-field nl-dce-done" data-nl-expr="/context/profile/firstName">First name</span>" .
- In the span there are two mandatory attributes:
- One is class which is static. No matter which personalization field you plan to use, it will always be class="nl-dce-field nl-dce-done".
- Another one is data-nl-expr which is the path of personalization field. For example, if you insert "firstName" personalization field from UI, the navigation path will be context→profile→firstName (as shown in the image below). In this case the path will be /context/profile/firstName. data-nl-expr="/context/profile/firstName".
