Message Templates

WhatsApp templates are message formats that have been registered and approved by Meta. Meta requires businesses to use message templates in business communication to avoid inappropriate usage and to ensure message quality for end users.

The following is an example of a template:

Hello {{1}}, your access code to {{2}} is {{3}}. If you did not initiate this request, kindly ignore this notification. Thank you.

The brackets with numbers are called parameters. They are the only parts of message templates that can be changed after approval. Thus, you can use the same message template multiple times and adjust only the parameters according to your requirements.

Templates are of the following types.

• Message: Contain only text messages.
• Media: Contain text and media such as images, videos, documents, and locations.
• Interactive: Contain text, media, and interactive buttons such as quick reply and call-to-action buttons.

Channel Options

Each channel element has generic features that are available in all channels and channel-specific features. This section shows how to configure the generic options.

Select a channel element in your flow to open the side panel and configure the following fields.

URL shortening and tracking

URL shortening

If the links (URLs) that you include in messages to end users are long or contain other parameters, end users might consider such links untrustworthy or spam.

Also, some channels, such as SMS, might have a limit on the number of characters in a message. If a message contains long URLss, it increases the length of the message. If a message exceeds the character limit, the message might be divided into multiple messages, which could increase costs.

Long URLs also increases screen space occupied by the URL on the end user's device, and makes the URL less readable.

URL shortening enables you to shorten the length of the URLs that you share with end users.

URL shortening is available for the following channels:

• LINE
• SMS
• Viber
• WhatsApp

URL shortening works differently depending on the settings you choose. These settings are applied to all the links in the message.

Your message might contain the following types of links.

• URLs that contain only a primary or default domain. Example: www.infobip.com.
• URLs that contain a custom domain or subdomain. Example: www.dev.infobip.com.

Shorten the URL for a default domain

Use this option to shorten URLs that contain only a primary or default domain. When you select this option, the entire URL is shortened.

(Optional) You can also remove the 'http' or 'https' prefix from the URL.

Example:

Original URL	../flow-elements#entry-points
Shortened URL	https://rrj.nu/x5T3jd2Y The entire URL is shortened.
Shortened URL with protocol removed	rrj.nu/x5T3jd2Y The entire URL is shortened, and the protocol https is removed.

Enable URL shortening for a default domain

Do the following:

1. In the flow, go to the channel element in which you want to enable URL shortening.
2. In the Message field, enter the message that contains the links to send to the end user.
3. In the Tracking and reporting section, select Shorten URLs.
4. (Optional) To remove the protocol from the URL, select Remove https:// from domain. 
5. In the choose a domain section, select default domain.
6. Continue configuring the channel element.

Shorten the URL for a custom domain

Use this option to shorten URLs that contain a custom domain or subdomain.

When you select this option, the URL is shortened such that it retains the custom domain. Use this option to send personalized, branded links to end users.

(Optional) You can also remove the 'http' or 'https' prefix from the URL.

Example:

Original URL	https://www.dev.infobip.com/docs/api/customer-engagement/moments
Shortened URL	https://www.dev.infobip.com/x5T3jd2Y The custom domain https://www.dev.infobip.com is retained. The URL content after the custom domain is shortened.
Shortened URL with protocol removed	www.dev.infobip.com/x5T3jd2Y The custom domain www.dev.infobip.com is retained, the URL content after the custom domain is shortened, and the protocol https is removed.

Prerequisites

Register your brand domain.

Enable URL shortening for a custom domain

Do the following:

1. In the flow, go to the channel element in which you want to enable URL shortening.
2. In the Message field, enter the message that contains the links to send to the end user.
3. In the Tracking and reporting section, select Shorten URLs.
4. (Optional) To remove the protocol from the URL, select Remove https:// from domain.

6. Continue configuring the channel element.

URL tracking

URL tracking helps you track the clicks for a link. You can identify which campaign links end users clicked, the number of times they clicked these links, and which end users clicked them.

To enable URL tracking, do the following:

1. In the flow, go to the channel element in which you want to enable URL tracking.
2. In the Content field, enter the message, which contains the link, to send to the end user.
3. Select Show advanced options.
4. Select Track URL clicks.
5. Continue configuring the channel element.

Data Payload

To customize your message, you can add data from stored or imported contacts. Example: first name or country.

In the Tracking and reporting > Reporting options section, select one or more data that you want to include. You can now add this data through placeholders in the message. This data is also included in message reports.

For the Mobile push channel, the predefined data payload is phone number (MSISDN) because of the technical implementation of Mobile push and In-app messages.

Delivery time window

Set the days, time, and time zone during which the flow sends the communication to end users.

Complete the fields in the Message scheduling > Delivery time window section.

You can also enable the flow to determine the best time to send messages to end users. For more information, refer to the send-time optimization documentation.

Message sending speed

Configure the number of messages that you want to send within a specified period (minutes, hours, or days).

Example: You configure to send 1000 messages in 1 day. After you set the limit and Infobip receives the first message, the 24-hour period starts regardless of when the daily limit has been met - in the first few hours or later. After the 24-hour period, another 1000 messages will go out.

Use this setting if you want to limit the number of messages that you send. Example: Your flow is for a promo campaign that encourages end users to place orders through your call center. If you send the message to all the audience at the same time, your call center might get high call volumes, which can result in long call wait times for end users. To avoid this situation, send messages at the speed that your call center can manage.

You can configure the Message sending speed in Send elements (Elements such as SMS, Email, and Viber, which send messages) and Call API integration.

Configure the fields in the Advanced settings > Message sending speed section.

Validity Period

Validity period is the period during which the flow tries to deliver the message to the end user's device. Use validity period to set the expiration period for the message.

Example: You want to send a communication to your audience. Some end users have switched off their mobile device. The system is unable to deliver messages immediately to these devices. The system periodically tries to deliver the message until the end of the validity period.

If the flow is unable to send the message before the validity period ends, the following happens.

• Unable to send for unknown technical reasons: The flow is redirected to the Failed branch.
• For all other reasons: The flow is redirected to the relevant branch.

All messages that you send to end users through channel elements in the flow have a validity period. The default and maximum validity periods are 48 hours.

To set a shorter period, use the Advanced settings > Validity period section in the side panel of the channel element. Specify the Period and select the unit as Hours or Minutes.

Channel Metrics

To quickly get the message data directly from Flow, hover over the channel element to see delivery numbers, click rates, opens, and more. The metrics availability depends on the channel in question.

The following delivery and click rate metrics are available:

• Message send - Number of messages sent by this element
• Total delivered - Number of engagements delivered by this element. A single person can receive multiple engagements.
• Delivery rate -  Percent of sent messages that were actually delivered.
• Total opens - Number of engagements that were opened for this element
• Open rate - Percent of delivered engagements that were actively opened by recipients
• Unique opens - Number of unique people who opened the engagement at least once.
• Click-through rate (CTR) - Percent of delivered messages that resulted in a clicked link.
• Total clicks - Number of links clicked.
• Unique clicks - Total number of unique people who clicked a link at least once.

Failover

Secure the message delivery by setting up backup channels. This means that if you send a message over one channel and it`s not delivered, another channel of your choice will be automatically used after a defined time.

When designing your campaign, remember that there is a validity period during which the platform will try to deliver the message over one specific channel. The default value is 48 hours. Also, make sure that all the recipients have all the required destinations set in their profiles.

To use this feature, add the Failover element to the flow you are designing and set up the channels.

Evaluate Inbound Message

Use this element to branch the flow based on specific words sent by the end user. Example: If the end user replies products, send them a list of all products. If the end user replies promotions, send them a list of only products that have promotions.

The default output of the element is If no response in 2 days.

Configure the element

Follow these steps to configure the element.

1. Select the channel for which you want to evaluate the message.
2. Select the recipient.
3. Define conditions to compare the end user's message with the value that you specify. If the condition is fulfilled, the next step in the flow is triggered.
4. (Optional) Save the inbound message information in variables.
5. Specify the time to wait for a response from the end user.

For more information, refer to the detailed instructions below.

Select the channel

In the Channels and conditions section, select the channel for which you want to evaluate the end user's message.

The default channel is SMS. To use a different channel, delete the existing channel and select the required one.

Select the recipient

Select the channel name to open the card. In the To recipient section, select the recipient.

Define conditions for the inbound message

Define conditions to compare the end user's message with the value that you specify. Configure the action that the flow needs to take if the condition is fulfilled.

You can specify multiple conditions within the element.

You can set conditions for the following:

• Message body: Compares the body of the message against the condition value.

• Anything: Use this option so that end users can continue the flow even if their message contains something that is not included in the conditions.

  Exact matches have a higher priority over Anything. Example: You have two flows that are waiting for a message from the same end user. In one flow, the condition is to match the exact word yes. In the other flow, the condition is Anything. The end user responds yes. In this case, the end user continues in the flow that matches the exact word.

• Button text (WhatsApp only): When the end user selects a button to respond, this condition compares the button text against the condition value.

• Button Payload (WhatsApp only): When the end user selects a button to respond, this condition compares the button payload against the condition value.

Use the following operators in the conditions.

• Is equal to person attribute - checks whether the message body contains the person attribute that you select.

  The case is ignored when comparing the value.

• Matches text - checks whether the end user's response matches the condition value exactly. The condition is fulfilled if the end user's response contains only the condition value and nothing else. You can specify multiple condition values.

  Example:
  Condition value: time
  End user's response: time. The condition is fulfilled.
  End user's response: timezone, time!!, what is the time? The condition is not fulfilled because the response contains additional characters that are not part of the condition value.

  The case is ignored when comparing the value.

• Matches RegEx - checks whether the message body contains a regular expression pattern that you define.

  Ignore case (Optional): Specify whether to ignore the case when evaluating the condition.

  Multiline (Optional): Use this option when you want to match against multiple lines of text. The validation is successful if any of the lines match.

  

• Contains text - checks whether the message body contains the keyword that you specify in the condition value. You can specify a group of characters, such as a symbol or keyword, in the condition value. You can specify multiple condition values.

  Example:
  Condition value: time
  End user's response: time, timeframe, 3times, time!!, what is the time? The condition is fulfilled because the message contains the keyword.

  The case is ignored when comparing the value.

• Contains word - checks whether the message body contains the exact word that you specify in the condition value. The word in the message body can have symbols or spaces before or after the word, but must not contain digits or other letters.

  Example:
  Condition value: time
  End user's response: time. The condition is fulfilled because the message contains the exact word.
  End user's response: time!!, what is the time? The condition is fulfilled because the message contains the exact word with either symbols or spaces before or after the word.
  End user's response: times, timeframe, timezone, 3times. The condition is not fulfilled because the word in the message contains additional characters that are not part of the condition value.

  The case is ignored when comparing the value.

You can specify multiple condition values.

The system follows the above order to process inbound messages. So, if a condition that has a higher priority is fulfilled, the flow takes the action for that condition and ignores the other conditions.

Save inbound message information in variables

You can also define variables to capture and store inbound message information.

Define the data that you want to capture from the inbound message. You can capture the following information.

• Message body
• Recipient
• Sender
• Message ID
• Gateway ID

You can save either the whole or part of the information.

• Whole text: Save the whole of the information.
• RegExp parse variable: Use a regular expression to capture a specific keyword in the message content.

For more information, refer to Flow Variables.

Specify the time to wait for a response

In the Response waiting time section, define how long the flow needs to wait for a response from the end user.
