The Laserfiche API “v1-alpha” routes are being deprecated and will be deactivated on December 1st, 2022. The deprecated routes contain “v1-alpha” in the URL. (see: https://api.laserfiche.com/repository/swagger/index.html?urls.primaryName=v1-alpha)
Please update your code to reference the released version “v1” Laserfiche API routes. (see: https://api.laserfiche.com/repository/swagger/index.html?urls.primaryName=v1).
To simplify the use of our Rest APIs, Laserfiche is supporting publicly available client libraries via NPM and NuGet. See Laserfiche API developer documentation at https://developer.laserfiche.com/libraries.html for more details.
