WhatsApp campaign creation: Step-by-Step

Name

(required)

The name of the campaign that will appear in the list of WhatsApp campaigns.

WhatsApp Account

(required)

Select one of the registered WhatsApp Business accounts. If only one account is connected, it is selected automatically, and this field will be disabled.

WhatsApp Template

(required)

Select the pre-approved template you'd like to use for the campaign.

Remember: Templates cannot be edited in Meiro. If you need to change the content, create and approve a new template in your WhatsApp Business account.

Header

(optional)

The header is the top part of your WhatsApp message and can include personalised text, images, or documents.

Warning: If you use text in the header, it must stay within the 60-character limit — including any personalisation variables (like {{offer_coupon}}) and the values they get replaced with (e.g., BLACKFRIDAY_25).

Example:
✅ Your offer code is {{offer_coupon}}.
→ Leaves enough room for the value.

❌ Enjoy our amazing offer today:  {{offer_coupon}}. → Already 60 characters before replacing the variable.

To avoid delivery errors, keep the header text short and leave space for the personalised value.

Body

(required)

This is the main text of your WhatsApp message. It can include dynamic placeholders like {{1}}, {{2}}, etc., which are replaced with real customer data when the message is sent.

You can:

• Use the attribute picker to search for and select specific attributes for personalisation.

• Use LiquidJS syntax to define fallback values, for example:
  {{customer_name | default: "there"}} → “Hi there” if the name is missing.

Always set default values for optional data to avoid message delivery failures.

Button

(optional)

When you select a template that includes buttons, Meiro CDP automatically displays the button configuration fields required for sending your campaign. Because buttons are defined at the template level, most settings are fixed. However, some fields allow you to supply personalised or dynamic values.

This section explains how each button type works in Meiro CDP and what you need to configure before sending your campaign.

If your selected template includes a Copy code or Copy offer code button, you must provide a value for the code.

Character Limits

To prevent message delivery failures, Meiro shows a helpful information message under the code input:

• Copy code → WhatsApp has a 15-character limit for this code.
  

  

• Copy offer code → WhatsApp has a 20-character limit for this code.
  

  

These limits are enforced by WhatsApp. If the value exceeds the limit, your message may be rejected by WhatsApp and will not be delivered.

Dynamic Values

You may use attributes to populate the code dynamically (e.g., {{customer_db.promo_code}}).

Important:

• All attribute values must comply with WhatsApp’s character limits.

• Consider validating your data before sending large campaigns.

Use Cases

• Verification flows (Copy code)

• Promo code campaigns (Copy offer code)

• Referral incentives

• Personalised discount programs

2. CTA Buttons (Visit Website / Call Support)

If your template includes CTA buttons, Meiro displays them automatically. CTA buttons are fixed at template creation, but some CTA types allow you to personalise the final value:

Visit Website

• Can use placeholders in the URL (if set in the template)

• You can insert attributes in Meiro (e.g., add customer ID or order number)

Call Support

• The phone number is fixed and cannot be changed in Meiro

Example:
A CTA button named Track Order may use a URL like:
https://store.com/orders/{{order_id}}

3. Quick-Reply Buttons

Quick-reply buttons require no configuration in Meiro.
They appear as part of the message, and users respond by tapping one of the listed options.

Meiro captures the user’s selection as an inbound message event, which you can use for:

• Targeting

• Journeys

• Automation rules

If a button includes dynamic placeholders (e.g., URLs or code values), make sure that:

• All attributes used in the button have valid, non-empty values

• Fallback/default values are defined in the template

• The final value is complete and formatted correctly for every recipient

If a dynamic value resolves to an empty or invalid value, WhatsApp will reject the message. Fallback values ensure a valid value is always sent.

Send test to

Enter a valid phone number, including the country code. The number must be in international format, starting with + or 00 (e.g., +65 9123 4567 or 0065 9123 4567).

Make sure this number has already opted in to receive WhatsApp messages; otherwise, the test message will not be delivered.

Profile ID

Enter the ID of any customer profile stored in your CDP. The system will use this profile’s data (e.g., name, order number, etc.) to personalise the test message.

You can find the profile ID in the URL when viewing a customer’s profile in Meiro.
