The following certificate authorities have been added to the list of certificate authorities trusted by LINE.

For more information on configuring Webhook URL settings, see Webhook URL settings.

LINE's APIs will support HTTP/2

LINE's APIs will support HTTP/2.

# Domain names subject to the update

  • api.line.me
  • api-data.line.me
  • access.line.me

# Supported HTTP versions

See this table for the differences before and after the update:

HTTP version Before update After update
HTTP/2
HTTP/1.1
HTTP/1.0

# Scheduled date of change

August 4, 2020 12:00 ~ 16:00 JST (GMT+9)

# Impact

If you are using any of the above APIs, please confirm that your app can communicate using the updated supported HTTP versions.

Due to this update, when using the above APIs from clients that support HTTP/2 or TLS 1.3, the handshake overhead is reduced and the connection efficiency is improved.

To use the latest protocols such as HTTP/2 and TLS 1.3, we recommend upgrading your development environment such as JDK and other development languages and LINE SDK to the latest versions.

# Other changes

For access the APIs from outside Japan, these 2 changes are made in addition to the above.

We will continue to improve the quality of the services we provide to our developers and we greatly appreciate your understanding.

LINE API's SSL root certificate authority has been changed

Added July 30, 2020

For access to the APIs from outside of Japan, the root certification authority will be changed after August 4, 2020. For more information, see the news on July 30, 2020, LINE's APIs will support HTTP/2.

We've changed the SSL certificate used in LINE's API servers. As a result, we've changed the root certificate authority from DigiCert to GlobalSign.

# Domain names subject to this change

  • api.line.me
  • api-data.line.me
  • access.line.me

# Date and time of change

  • For access from Japan: July 10, 2020 17:17 ~ 17:54 JST (GMT+9)
  • For access from outside Japan: August 4, 2020 12:00 ~ 16:00 JST (GMT+9)

# Impact

Due to this update, if an SSL communication problem occurs on the client side using the LINE API, it is possible that the corresponding root certificate (GlobalSign Root R3) does not exist.

If you observe this problem, please update the root certificate to the latest version on the client side using the API.

We will continue to improve the quality of the services we provide to our developers and we greatly appreciate your understanding.
