This is the standard usage pattern. You should not manually include the **curly brackets** (**{}**) in the dynamic attribute’s input field. The system adds them automatically. ## Customize date format You can format your default and custom data attributes, such as {{birthday}}, in different formats. Below is the sample formatting syntax for the SMS design: > {{attribute_name|time-format=DD-MM-YYYY}} If you want to customize your values, you can specify and write your preferred format in the fallback field. Moreover, you can either apply a customization or assign a fixed value to the fallback field; both options are available and can be used simultaneously. You have the flexibility to apply customization and assign a fixed date to the fallback field; these options are not mutually exclusive and can be used together. Below, you can see the date example: > Fixed Date|time-format=MM-DD-YYYY You can customize your date formatting. Once you insert your attribute representing the date, the date value of this attribute will be displayed in a human-readable format. You can use this for any date-type attribute like birthday, registration date, release date, etc. Below, you can see some examples: > {{custom_field|time-format=DD-MMM-YYYY}} {{custom_field|time-format=MMMM/DD/YY}} {{custom_field|time-format=MMMM/D/YY}} The date parameters in the example above have different formats, such as *DD, D, YY*, and *YYYY*. When you use the first example as an attribute in your SMS message, it can be converted to a user as *07-Nov-2024,* while the second is *November/07/24*. You can customize your attribute values using the following formats: | Formatting | Description | Example | | --- | --- | --- | | DD | Day as number with zero | 07 | | D | Day as number without zero | 7 | | M | Month as number with zero | 09 | | MM | Month as number without zero | 9 | | MMM | Month as text in short format | Mar | | MMMM | Month as text in full format | March | | YY | Last two digits of the year | 23 | | YYYY | Year as number in full format | 2023 | You can also use custom time formats with different time parameters. Below, you can see some examples: > {{custom_field|time-format=hh:mm:ss}} {{custom_field|time-format=hh:mm}} {{custom_field|time-format=HH:mm:ss}} The time parameters in the example above have different formats like hh, HH, and mm. You can customize your attribute values using the following formats: | H, HH, h, hh | Hour | | --- | --- | | M, MM, m, mm | Minute | | s, ss | Second | | A, a | PM and AM | If the time value is exactly 00:00:00, it will always be converted to 12:00:00. You can use both date and time formats inside the same dynamic content in both your SMS campaigns and Architect SMS campaigns. For example, the {{custom_field|time-format=YYYY-MM-DD hh:mm:ss A}} attribute can be converted as *2024-09-11 11:21:13 PM*. Below, you can see all supported date and time formats. The results are created based on 2024-04-11T15:21:13Z. **Date and Time Formats** | Date and time format | Result | | --- | --- | | M/DD/YYYY | 4/11/2024 | | MM/DD/YYYY | 04/11/2024 | | MMM/DD/YYYY | Apr/11/2024 | | MMMM/DD/YYYY | April/11/2024 | | M/DD/YY | 4/11/24 | | MM/DD/YY | 04/11/24 | | MMM/DD/YY | Apr/11/24 | | MMMM/DD/YY | April/11/24 | | DD/M/YYYY | 11/4/2024 | | DD/MM/YYYY | 11/04/2024 | | DD/MMM/YYYY | 11/Apr/2024 | | DD/MMMM/YYYY | 11/April/2024 | | DD/M/YY | 11/4/24 | | DD/MM/YY | 11/04/24 | | DD/MMM/YY | 11/Apr/24 | | DD/MMMM/YY | 11/April/24 | | DD-M-YYYY | 11-4-2024 | | DD-MM-YYYY | 11-04-2024 | | DD-MMM-YYYY | 11-Apr-2024 | | DD-MMMM-YYYY | 11-April-2024 | | DD-MM-YY | 11-04-24 | | YYYY-M-DD | 2024-4-11 | | YYYY-MM-DD | 2024-04-11 | | YYYY-MMM-DD | 2024-Apr-11 | | YYYY-MMMM-DD | 2024-April-11 | | M/D/YYYY | 4/11/2024 | | MM/D/YYYY | 04/11/2024 | | MMM/D/YYYY | Apr/11/2024 | | MMMM/D/YYYY | April/11/2024 | | M/D/YY | 4/11/24 | | MM/D/YY | 04/11/24 | | MMM/D/YY | Apr/11/24 | | MMMM/D/YY | April/11/24 | | D/M/YYYY | 11/4/2024 | | D/MM/YYYY | 11/04/2024 | | D/MMM/YYYY | 11/Apr/2024 | | D/MMMM/YYYY | 11/April/2024 | | D/M/YY | 11/4/24 | | D/MM/YY | 11/04/24 | | D/MMM/YY | 11/Apr/24 | | D/MMMM/YY | 11/April/24 | | M-D-YY | 4-11-24 | | MM-D-YY | 04-11-24 | | MMM-D-YY | Apr-11-24 | | MMMM-D-YY | April-11-24 | | D-M-YYYY | 11-4-2024 | | D-MM-YYYY | 11-04-2024 | | D-MMM-YYYY | 11-Apr-2024 | | D-MMMM-YYYY | 11-April-2024 | | D-M-YY | 11-4-24 | | D-MM-YY | 11-04-24 | | D-MMM-YY | 11-Apr-24 | | D-MMMM-YY | 11-April-24 | | MMM D, YYYY | Apr 11, 2024 | | MMMM D, YYYY | April 11, 2024 | | YYYY-MM-DD hh:mm:ss | 11/04/2024 03:21:13 | | hh:mm:ss | 03:21:13 | | YYYY-MM-DD hh:mm:ss A | 2024-04-11 15:21:13 PM | | YYYY-MM-DD hh:mm:ss a | 2024-04-11 15:21:13 pm | | H:m:s | 15:21:13 | | H:m:ss | 15:21:13 | | HH:m:ss | 15:21:13 | | HH:m:ss | 15:21:13 | | h:m:s | 03:21:13 | | h:m:ss | 03:21:13 | | hh:m:s | 03:21:13 | | hh:m:ss | 03:21:13 | | H:mm:s | 15:21:13 | | H:mm:ss | 15:21:13 | | HH:mm:s | 15:21:13 | | HH:mm:ss | 15:21:13 | | h:mm:s | 03:21:13 | | h:mm:ss | 03:21:13 | | hh:mm:s | 03:21:13 | | hh:mm:ss | 03:21:13 | | D MMM | 11 Apr | | D MMMM | 11 April | Once you complete designing your SMS campaign, make sure to send a test SMS to yourself to make sure your attributes function as you set them. ## Customize number format You can insert separators to number-type default and custom attributes—such as {{price}}, {{amount}}, and {{phone_number}}—so that the dynamic content in your SMS is more readable for recipients. You can use a comma (,), a dot (.), a space ( ), and an apostrophe (') as thousand and decimal separators. **Syntax example**: {{dynamic_attribute|number-format=thousand_separator,decimal_separator}} - **thousand_separator:** Specifies the character used to separate thousands. - **decimal_separator:** Specifies the character used to separate decimals. If you customize the number format for any dynamic attribute, you cannot add a fallback value to that attribute. #### Examples Below are some examples of the usage of the thousand and decimal separators. | Separator | Syntax | Example | | --- | --- | --- | | Dot as thousand Comma as decimal | {{last_purchase_amount\|number-format=dot,comma}} | 1.234.567.890,00 | | Comma as thousand Dot as decimal | {{last_purchase_amount\|number-format=comma,dot}} | 1,234,567,890.00 | | Apostrophe as thousand Comma as decimal | {{last_purchase_amount\|number-format=apostrophe,comma}} | 1'234'567'890,00 | | Space as thousand Dot as decimal | {{last_purchase_amount\|number-format=space,dot}} | 1 234 567 890.00 | | Dot as thousand Comma as decimal (integer) | {{last_purchase_amount\|number-format=dot,comma}} | 1.234.567.890,00 | | Dot as thousand Dot as decimal (integer) | {{last_purchase_amount\|number-format=dot,dot}} | 1.234.567.890.00 | | Apostrophe as thousand Dot as decimal | {{last_purchase_amount\|number-format=apostrophe,dot}} | 1'234'567'890.00 | | Dot as thousand Empty decimal | {{last_purchase_amount\|number-format=dot}} | 1.234.567.890.00 | | Comma as thousand Empty decimal | {{last_purchase_amount\|number-format=comma}} | 1,234,567,890.00 | | Apostrophe as thousand Empty decimal | {{last_purchase_amount\|number-format=apostrophe}} | 1'234'567'890.00 | | Space as thousand Empty decimal | {{last_purchase_amount\|number-format=space}} | 1 234 567 890.00 | | Empty thousand Comma as decimal | {{last_purchase_amount\|number-format=,comma}} | 1234567890,00 | | Empty thousand Dot as decimal | {{last_purchase_amount\|number-format=,dot}} | 1234567890.00 | | Empty thousand Apostrophe as decimal | {{last_purchase_amount\|number-format=,apostrophe}} | 1234567890'00 | | Empty thousand Space as decimal | {{last_purchase_amount\|number-format=,space}} | 1234567890 00 | If you want to customize your values, you can specify and write your preferred format in the fallback field.
