v8.17.0 Add forbidPartialDelivery option to the Narrowcast Limit Object

What's Changed

• Add forbidPartialDelivery option to the Narrowcast Limit Object by @github-actions[bot] in #634

Add forbidPartialDelivery option to the Narrowcast Limit Object

We add a new forbidPartialDelivery option to the Narrowcast Limit Object.

When set to true, this option prevents messages from being delivered to only a subset of the target audience.
If partial delivery occurs, the narrowcast request will succeed but fail asynchronously.
You can verify whether the message delivery was canceled by checking the narrowcast message progress.

This property can only be set to true when upToRemainingQuota is also true.

For more details, see the https://developers.line.biz/en/news/2025/10/21/narrowcast-message-update/.

Example:

bot.Narrowcast(
	&messaging_api.NarrowcastRequest{
		Messages: []messaging_api.MessageInterface{
			messaging_api.TextMessage{
				Text: "Hello",
			}
		},
		Limit: &messaging_api.Limit{
			Max: 1000,
			UpToRemainingQuota: true,
			ForbidPartialDelivery: true
		}
	}
)

(original PR is line/line-openapi#114)

Use cases

Previously, when upToRemainingQuota was set to true, messages could be partially delivered if the remaining message quota was smaller than the target audience size.
With the new forbidPartialDelivery option, you can now ensure that such partial deliveries do not occur.

• Ensuring that a campaign message is sent only if it can reach the full target audience, avoiding incomplete distributions.

v8.16.0 Add an Option to Skip Webhook Signature Verification

What's Changed

✨ Add an Option to Skip Webhook Signature Verification

• Add option to skip signature verification by @habara-k in #595

With this release, developers can now optionally skip signature verification when parsing incoming webhook requests. This new capability is especially useful in scenarios where the channel secret may change, potentially causing temporary signature mismatches.

Example Usage:

opt := &webhook.ParseOption{
	SkipSignatureValidation: func() bool { return true },
}
cb, err := webhook.ParseRequestWithOption(os.Getenv("LINE_CHANNEL_SECRET"), req, opt)

When signature verification is skipped, the signatureValidator will not be invoked. This allows webhook requests to be processed even if their signatures do not match the current channel secret used for verification.

This feature is particularly helpful in high-availability systems where avoiding downtime or message loss during configuration updates is critical.

This release introduces Coupon API support to the Messaging API, enabling developers to create, manage, and deliver coupons directly through bot integrations. These new features mirror capabilities previously only available through the LINE Official Account Manager, offering greater flexibility in automating coupon workflows via the Messaging API.

✨ New API Endpoints

  Create a new coupon, including metadata such as title, description, validity period, image URLs, acquisition conditions, and reward details (e.g., fixed-amount discounts).

• GET /v2/bot/coupon
  Retrieve a list of all coupons associated with your bot.

• GET /v2/bot/coupon/{couponId}
  Fetch detailed metadata of a specific coupon.

• PUT /v2/bot/coupon/{couponId}
  Mark a coupon as expired.

💬 Messaging API Enhancements

• Added support for a new message type: type=coupon
  You can now send coupons directly to users using the Messaging API, similar to sending text, image, or template messages.

📌 Example Use Cases

• Create a 1000 yen off coupon
• Send the coupon to a user using the new coupon message type

For detailed usage examples, see the official documentation.
