Hi, I have updated the shared doc [1] by adding "List of Admin Services to be used for DAS 3.1". Feel free to add-in your suggestions as well.
Also, are their any documentation available on specific Admin Services APIs I have mentioned in doc? Such as a Reference Guide describing the methods and parameters of individual Admin Services APIs. I am already aware of the general documentation on Admin Services available at [2] [1] - https://docs.google.com/document/d/154ndex3OBoE0zNOLHatmMOvt2JHh9RJya2VdHlHOTl4/edit?usp=sharing [2] - https://docs.wso2.com/display/DAS310/Calling+Admin+Services+from+Apps Thanks, Madhawa On Tue, May 9, 2017 at 11:11 AM, Sriskandarajah Suhothayan <s...@wso2.com> wrote: > +1 for the approach. > We will add the classes > > On Tue, May 9, 2017 at 12:05 AM Madhawa Vidanapathirana < > madhawavidanapathir...@gmail.com> wrote: > >> Hi, >> >> I will look into REST side also then.
