With release 20.14 a year ago, the REST API Versions /v1 and /v2 have been marked as obsolete/deprecated and a migration guide has been published. With the 21.16 release, those versions have been removed: • /api/v1 (also accessible via /api/v1.0) • /api/v2 (also accessible via /api/v2.0) The REST migration guide, which contains also some more information about the different API versions and in particular about the differences from version 1.0 or 2.0 to newer versions, is available here: Migration Guide Please mind that the guide describes the migration to v4, but similar functionality will also be applicable for a migration to /v5. The swagger documentation, which is our REST API reference documentation, is available here: https://demo.esignanywhere.net/Api/swagger/ui/index |
