API Methods

It is somewhat difficult to find the correct version of API and the year that it was published. Here we have listed, to the best of OLI's ability, to correlate the published year with the API version number. We have not attempted to correlate the revision years.

For OLI's purposes, we use API versions 5.0 (1992) and 8.0 (2006) in our code.

API Version Published Year Notes
1 1966
2 1970
3 1977
4 1982
5 1992 OLI uses this version
6 1994 This version does not exist in the official record. This version was bad and API pulled it.
7 2005
8 2006 OLI uses this version
9 2013
10 2018
