Amidst our introduction of the max-price feature on the Marketing Messages API for WhatsApp, there is no change to how we charge on the WhatsApp Business Platform. We continue to charge on a per-message basis, as outlined here.

The max-price feature will become available via Limited Beta as of mid-May and be optional throughout 2026.

What is a max-price?

As announced in March 2026 -- in 2026, we’re introducing new pricing features on the Marketing Messages API for WhatsApp to enable businesses to drive higher ROI and have more control to optimize spend for their marketing messaging campaigns.

Our first pricing feature allows businesses to set a maximum price (max-price) per marketing message delivery; when a max-price is set, Meta will charge that max-price or lower for delivery. Businesses can choose to set a max-price the same as, lower than, or higher than the published rate to achieve their objectives per campaign.

Lower costs while maintaining delivery rates similar to current WhatsApp campaigns, by setting max-prices the same as published rates.

Target a broader range of customer cohorts on WhatsApp at lower cost, by setting max-prices lower than published rates.

Increase delivery rates when customer engagement matters most, like during holidays and peak sales periods, by setting max-prices higher than published rates.

The second pricing feature is the reach estimation tool, which helps businesses set the right max-price by helping them understand estimated delivery rates and costs at different max-prices.

Max-price explainer

The max-price feature allows you to set the maximum price you are willing to pay per message delivery. You are charged your max-price or lower. In the API, you express this as a bid_amount value per 1,000 deliveries within the bid_spec object.

Phased roll-out of the max-price feature

We plan to roll out our max-price feature in 3 phases:

Limited Beta starting mid-May 2026 -- Any partner and any directly-integrated business can integrate and use the max-price feature and reach estimation tool. Each partner can enable these features for a limited number of clients.

Open Beta starting October 2026 -- Any partner can enable these features for all their clients.

General Availability (GA) as of Q2 2027 -- The max-price feature will become required in eligible geographies and fixed, published rates for marketing messages will only apply on the Cloud API.

Before you begin

To use the max-price feature, you must:

Have an active WhatsApp Business Account that has been onboarded to the Marketing Messages API for WhatsApp.

Be in a country eligible for MM API for WhatsApp.

Recommendations

Set your max-price at the template level. The bid_amount in bid_spec is what Meta’s delivery system optimizes against. Setting the right max-price when you create the template gives the system the best signal for delivery optimization.

The per_message_bid_multiplier scales the template’s bid_amount up or down for individual messages, but the delivery system generally gives better performance optimizing based on the original template-level bid_amount on large amount.

For example, if you set a template’s bid_amount to 50,000 and then apply a multiplier of 2.0 on every message, delivery performance might differ from setting the template’s bid_amount to 100,000 directly -- even though the effective max-price is the same. Hence we recommend setting up the bid at template level and update the template’s bid_spec if needed rather than changing the message level multiplier as a workaround.

Ramp up traffic gradually. When sending messages with a new max-price template for the first time, increase volume slowly before sending at scale. This aligns with Template pacing best practices and helps the delivery system optimize effectively.

Create templates with max-price

Use the Message Templates API to set a maximum price and include the bid_spec object in the request body.

Request syntax

curl 'https://graph.facebook.com/<API_VERSION>/<WHATSAPP_BUSINESS_ACCOUNT_ID>/message_templates' \
  -H 'Authorization: Bearer <ACCESS_TOKEN>' \
  -H 'Content-Type: application/json' \
  -d '
  {
    "name": "seasonal_sale_promo",
    "category": "MARKETING",
    "language": "en",
    "components": [
      {
        "type": "BODY",
        "text": "Shop our seasonal sale! Up to 50% off selected items."
      }
    ],
    "bid_spec": {
      "bid_amount": "<BID_AMOUNT>",
      "bid_strategy": "LOWEST_COST_WITH_BID_CAP"
    }
}'

If bid_spec is not included, the template uses standard rate card pricing.

Request parameters

Placeholder	Description	Example Value
`<ACCESS_TOKEN>` String	Required. System token or business token.	`EAAA...`
`<API_VERSION>` String	Optional. Graph API version.	v25.0
`<WABA_ID>`String	Required. WhatsApp Business Account ID.	`102290129340398`
`<BID_AMOUNT>` int	Required. Maximum price per 1,000 message deliveries, expressed in your WABA currency’s smallest unit (cents for USD, paise for INR, peso for MXN). See supported currencies for a list of currencies.	`87000`

Calculating max-price amounts

The bid_amount represents your max-price per 1,000 deliveries in your WABA currency’s smallest unit. To convert from your desired per-delivery price:

Convert your desired per-delivery price to your WABA currency’s smallest unit

Multiply by 1,000 to express the value per 1,000 deliveries

Example: To set a max-price of ₹0.87 per delivery:

Convert to paise: 0.87 Rupees = 87 paise

Multiply by 1,000: 87 x 1,000 = 87,000

Set bid_amount to 87000.

Example: To set a max-price of $0.05 USD per delivery:

Convert to cents: $0.05 = 5 cents

Multiply by 1,000: 5 x 1,000 = 5,000

Set bid_amount to 5000.

Retrieve max-price information

Use the Template API to get the max-price setting on an existing template.

Request syntax

curl 'https://graph.facebook.com/<API_VERSION>/<TEMPLATE_ID>/?fields=bid_spec' \
  -H 'Authorization: Bearer <ACCESS_TOKEN>'

Request parameters

Placeholder	Description	Example Value
`<ACCESS_TOKEN>` String	Required. System token or business token.	`EAAA...`
`<API_VERSION>` String	Optional. Graph API version.	v25.0
`<TEMPLATE_ID>` String	Required. ID of the WhatsApp message template.	`1733678867511493`

Example response

{
  "bid_spec": {
    "bid_strategy": "LOWEST_COST_WITH_BID_CAP",
    "bid_amount": 87000
  },
  "id": "1733678867511493"
}

Update max-price for templates

Use the Template API to update the max-price setting on an existing template.

You can update the bid_spec on templates that were originally created with a max-price. The same parameters apply.

You cannot add bid_spec to an existing template that was created without it. You must create a new template with bid_spec included.

Other constraints follow the standard template editing limits:

Approved templates: Up to 100 edits per hour, 2,400 per day

Rejected or paused templates: Unlimited edits

Request syntax

curl 'https://graph.facebook.com/<API_VERSION>/<TEMPLATE_ID>/' \
  -H 'Authorization: Bearer <ACCESS_TOKEN>' \
  -H 'Content-Type: application/json' \
  -d '{
  "bid_spec": {
    "bid_strategy": "LOWEST_COST_WITH_BID_CAP",
    "bid_amount": <BID_AMOUNT>
  }
}'

Request parameters

Placeholder	Description	Example Value
`<ACCESS_TOKEN>` String	Required. System token or business token.	`EAAA...`
`<API_VERSION>` String	Optional. Graph API version.	v25.0
`<TEMPLATE_ID>` String	Required. ID of the WhatsApp message template. The template must have been originally created with `bid_spec`.	`1733678867511493`
`<BID_AMOUNT>` int32	Required. Updated maximum price per 1,000 message deliveries, expressed in your WABA currency’s smallest unit.	`4000`

Adjust max-price when sending messages

The message-level max-price multiplier is subject to change during the beta period.

Use the Marketing Messages API to apply a multiplier at sending time to adjust the template-level max-price for individual messages. This allows you to max-price higher or lower without editing the template.

Request syntax

curl 'https://graph.facebook.com/<API_VERSION>/<WHATSAPP_BUSINESS_PHONE_NUMBER_ID>/marketing_messages' \
  -H 'Authorization: Bearer <ACCESS_TOKEN>' \
  -H 'Content-Type: application/json' \
  -d '{
  "recipient_type": "individual",
  "messaging_product": "whatsapp",
  "to": "<WHATSAPP_USER_PHONE_NUMBER>",
  "type": "template",
  "template": {
    "name": "seasonal_sale_promo",
    "language": {
      "code": "en"
    }
  },
  "bid_spec": {
    "per_message_bid_multiplier": "<PER_MESSAGE_BID_MULTIPLIER>"
  }
}'

In this example, the multiplier of 1.5 increases the template’s bid_amount by 50%. If the template’s bid_amount is 2000, the effective max-price for this message becomes 3000.

Request parameters

Placeholder	Description	Example Value
`<ACCESS_TOKEN>` String	Required. System token or business token.	`EAAA...`
`<API_VERSION>` String	Optional. Graph API version.	v25.0
`<WHATSAPP_BUSINESS_PHONE_NUMBER_ID>` String	Required. WhatsApp business phone number ID.	`106540352242922`
`<WHATSAPP_USER_PHONE_NUMBER>` String	Required. WhatsApp user phone number.	`+16505551234`
`<PER_MESSAGE_BID_MULTIPLIER>` Float	Optional. Default: `1` A positive multiplier applied to the template’s `bid_amount`. For example, `1.5` increases the max-price by 50%, `0.5` decreases it by 50%, and `1` (default) uses the template’s max-price amount unchanged.	`1.5`

Estimate reach and costs

The Reach estimation helps you understand your expected deliveries and costs at different max-price levels.

Request syntax

Use the WhatsApp Business Account API to get the estimated delivery ranges and cost ranges at various max-price amounts.

Estimates are generated using historical data and are for informational and planning purposes only. They do not guarantee future delivery outcomes, costs, or performance. Actual results may differ due to changes in platform conditions or other variables.

The targeting_spec value must be serialized JSON. For example:

curl 'https://graph.facebook.com/<API_VERSION>/<WHATSAPP_BUSINESS_ACCOUNT_ID>/reachestimate?targeting_spec={"geo_locations":{"countries":["IN"]}}&date_interval=<DATE_INTERVAL>' \
  -H 'Authorization: Bearer <ACCESS_TOKEN>'

Request parameters

Placeholder	Description	Example Value
`<ACCESS_TOKEN>` String	Required. System token or business token.	`EAAA...`
`<API_VERSION>` String	Optional. Graph API version.	v25.0
`<WABA_ID>`String	Required. WhatsApp Business Account ID.	`102290129340398`
`<DATE_INTERVAL>` Enum	Required. Lookback period for the historical data used to generate estimates. One of: `L1D` (last 1 day), `L7D` (last 7 days), `L14D` (last 14 days), `L28D` (last 28 days).	`L7D`
`<TARGETING_SPEC>` JSON	Required. Serialized JSON specifying geographic targeting. Must include `geo_locations` with a `countries` array.	`{"geo_locations":{"countries":["IN"]}}`

Example response

{
  "waba_currency": "USD",
  "estimates": [
    {
      "bid_amount": 400,
      "users": 1000,
      "lower_bound_deliveries": 500,
      "upper_bound_deliveries": 570,
      "cost_lower_bound": 389.74,
      "cost_upper_bound": 390.74
    },
    {
      "bid_amount": 520,
      "users": 1000,
      "lower_bound_deliveries": 600,
      "upper_bound_deliveries": 650,
      "cost_lower_bound": 400.74,
      "cost_upper_bound": 510.74
    }
  ]
}

The response contains multiple estimates entries at different max-price amounts, allowing you to compare expected delivery volumes and costs across price points.

Metrics and billing

Messages sent with or without the max-price feature use the same Marketing Lite product type (SKU) for billing purposes.

Marketing messages sent with max-price appear in analytics with the following identifiers:

Pricing Analytics/<WHATSAPP_BUSINESS_ACCOUNT_ID>?fields=pricing_analytics: pricing_category = MARKETING_LITE

Template Analytics/<WHATSAPP_BUSINESS_ACCOUNT_ID>?fields=template_analytics: product_type = MARKETING_MESSAGES_LITE_API

Webhooks use lowercase marketing_lite for pricing.category, while analytics APIs use uppercase MARKETING_LITE for pricing_category.
