Hi! This is the LINE Developer Relations team, thanking you for using LINE@.

As a result of our “Redesign” project, from mid-June 2019,we’re turning all LINE@ accounts with Developer Trial Plans intoLINE Official Accounts with Free Plans.
Check out our press release about the “Redesign” project.
Changes due to the “Redesign” project
The Developer Trial Plan, first released in 2016, allowed developers to build trial apps based on products provided by the LINE platform, such as Messaging API. Under this plan, your account couldn’t have more than 50 LINE friends, but you could use the Messaging API for free — which normally required a paid plan. (The rules were different from country to country.)
With this “Redesign” project, billing for LINE Official Accounts will change from pay-per-account to pay-per-use, based on the number of messages sent. However, the Free Plan will have more capabilities than before, and you will be able to send up to a certain number of push messages with the Messaging API for free each month. To send more push messages, you’ll need to change from the Free Plan to the Paid Light (Basic) Plan or the Standard (Pro) Plan.
Answers to questions you might have
We have prepared a set of questions that might be frequently asked after this change. Hopefully, this will help you understand the changes in more detail.
About the new plan
What kind of plan is the Free Plan?
It is a LINE Official Account Plan that lets you send a certain number of free messages per month using the publicly available Messaging API, with no limit on the number of friends. The number of free messages you can send depends on the country in which your account is registered.
Can I change from the Free Plan to another plan?
Yes, you can change your plan on the new LINE Official Account Manager administration page.
When will my existing Developer Trial Plan with LINE@ account be migrated to a Free Plan LINE Official Account?
We will migrate accounts sequentially (oldest to newest), starting in mid-June 2019. We’ll notify you on the news page of the LINE Developers site as soon as the date is confirmed.
About migrating to the new plan
How do I migrate my account?
Your account will be migrated automatically.
NOTE: For LINE@ accounts with plans other than the Developer Trial Plan, such as the LINE@ “Pro (API)” Plan, you’ll find a button for migrating to the LINE Official Account on the LINE@ MANAGER. Please carry out the migration yourself. For LINE@ accounts with the Developer Trial Plan, there is no such button.
How will I know that I was migrated to a LINE Official Account?
When you log in, you’ll see the new LINE Official Account Manager administration page.
During the migration period (from mid-June 2019 until the migration to LINE Official Accounts is complete), should I refrain from development?
No, please continue working as usual. However, if you send more than a certain number of push messages during June, a transmission error may occur.
After migrating to the new plan
Is it possible that I will not be able to send messages when my Developer Trial Plan LINE@ Account is migrated?
Yes. There is a limit on the number of push messages you can send per month. The limit depends on the country in which your account is registered. Since we are employing pay-per-use scheme with this migration, if you reach the maximum number of push messages in the month of migration, you won’t be able to send more until the end of the month.
Will an error message be displayed if I reach the number of messages I can send for free?
Yes. When the message limit is reached, the LINE Platform displays status code 429 with the error message “You have reached your monthly limit.”
Will the code implemented in my Developer Trial Account still work after migration?
Yes. If you have any problems, please contact dl_developer_relations@linecorp.com.
How many messages can I send in one message delivery?
You can send up to 3 messages in one delivery on the new Account Administration Manager page. In addition, you can send up to 5 messages per API request by using the Messaging API.
We have multiple people managing one LINE@ account. Can we manage it in the same way after the migration?
Yes. The LINE Official Account Manager settings will be migrated to the new plan without changes.
Can I use LINE Beacon and LINE Things (which I used for experiments and testing) after migration?
Yes, you will be able to use both. For commercial use, please contact dl_developer_relations@linecorp.com.
Lastly
Before the “Redesign” project, you couldn’t migrate from the Developer Trial Plan to another LINE@ plan. Also, when releasing a service, you had to create a new LINE@ account and re-establish the link with your Bot app. After the “Redesign” project, LINE Bots developed under a Free Plan will be available for use as official services.
However, since the billing method will change to pay-per-use, you’ll need to carefully consider how your services will communicate with end users. It’s important that you maximize the impact and efficiency of each message.
At LINE, we’ll continue to improve the quality of products provided on the LINE platform, such as Messaging API, so that you can develop services more easily. We hope that developers will also take advantage of LINE’s Messaging API, LIFF, and other products to develop services that provide superior user experiences.
