在使用WhatsApp API时，费用主要分为两类：租用号码费用和消息发送费用。本文将详细介绍这两类费用及其具体计算方式，以帮助用户更好地了解 WhatsApp API 的成本结构。
租用号码费用
WhatsApp API 的号码租用费根据所选号码包的不同而有所差异，常见的号码包类型包括单号码包、双号码包和模板号码包。以下是具体说明：
|
提示 有关号码包详细解释请查阅：了解号码包介绍与差异 |
如何租用号码？
平台号码可在【集成 】- 【WhatsApp API】- 【添加号码】- 自助买号 内进行租用
号码使用时间限制
每个号码在每 24 小时内，可以主动向 250 个会话发起消息。
|
提示 此外，如果您使用自建号或通过第三方平台创建的号码，则无需支付租号费用。可通过以下链接了解更多信息： |
消息发送费用
消息发送费用因国家/地区不同而有所差异，且分为以下三种类型：
-
红色费用：代表模板类型费用，不同模板类型的费用不同。在申请模板审核时，您可以选择适合的模板类型。
-
黄色费用（免费）：当客户主动与您联系时，产生的会话费用。（自2024年11月开始，WhatsApp宣布免去服务会话费）
-
蓝色费用：在会话期间，向客户发送的每条消息费用需要收取的平台服务费。
费用计算方式
我们可以通过以下公式来计算消息发送的具体费用。
主动群发消息费用
主动群发消息的费用为红色模板类型费用+蓝色消息费用。
|
主动群发消息费用 主动群发消息费用=(红色费用 + 蓝色费用) * 消息数量 |
客户主动发起会话费用
当客户主动联系且你回复客户之后，会产生黄色费用（免费）+蓝色消息费用。
|
客户主动发起会话费用 假设一个客户向您主动发起会话，就会开启24小时的服务会话期，您每个回复都会收取$0.005的服务费。 |
费用收取周期
- 红色费用： 24 小时收取一次
- 蓝色费用：每回复客户一条都需要收取
实例计算
假设您需要群发 1000 个客户，使用的模板类型为红色的市场营销，那么在发送时，您需要支付市场营销模板费用以及每条消息的发送费用。
费用计算公式为：
(红色费用 + 蓝色费用) * 消息数量
将数据代入公式：
(0.0250 + 0.005) * 1000 = $30
因此，发送 1000 条消息的费用为$30。
