Hi Shiv,
I'm glad the protos helped! For your first issue, could you please provide the complete detailed request and response logs for the call
via Reply privately to author so I can further investigate the issue? You can find information on enabling logging
here.
For the sitelink extension recommendations, you should getRecommendedExtensions like you already did and from there, you can pull the specific attributes of the sitelink that is recommended such as the link_text or line1/line2. The attributes are listed
here.
For the search partners opt in recommendation, there is no information to extract other than the campaign ID since the recommendation is simply telling you to opt into search partners for that specific campaign.
