[Updated] Publish API documentation to get a permanent link

Added on July 15, 2020

There was a mistake in the API method name. We've corrected the mistake and apologize for any inconvenience caused by this error.

Incorrect:

liff.permanentLink.setExtraQueryParams()

Correct:

liff.permanentLink.setExtraQueryParam()

The LIFF SDK keeps a permanent link for the current page. We'll publish the documentation of the API that handles this permanent link.

  • liff.permanentLink.createUrl()
  • liff.permanentLink.setExtraQueryParam()

These APIs are already included in the latest LIFF SDK, so the LIFF SDK version doesn't change.

For more information on how to get a permanent link, see Get a permanent link for the current page in the LIFF documentation.
