For one of our clients we’re seeing the same contacts returned on multiple pages. For an example see:
There are 16 duplicate contacts across those two pages:
The entries are almost entirely, but not exactly, the same. The only differences are in the profile-token and profile-url. See the attached image.
Also, at least for some of these, the two profile URLs appear to resolve to exactly the same HTML.
This appears to us to be a defect in the API when paging large numbers of contacts. We also don’t see a practical solution to this that is scalable and doesn’t require us to store an indeterminate number of contacts in memory.
This is an urgent issue for our customer. Any help we can get with this would be greatly appreciated.
