Finally. PerceptiveMCAPI v1.2.4 Beta has been released.
  • Supports the Interest Grouping Api changes announced by MailChimp Api v1.2.6
  • Wrapper enhancements for easier customization & integration
  • Wrapper bug fixes & minor tweaks
  • MailChimp Api v1.2.7, EXCEPT 'Static Segments' (to be included in Beta 2)
Make sure you read the changelog in the download -- there is one small, but annoying "breaking change" relating to input parameters.

Short version; where you used to specify: input.propertyname, you now need to use input.parms.propertyname.

Beta 2 is targeted for Aug 1.

Hi David:

The new beta release is great!  Thanks for your great work on this.

Not sure if this is the correct place to post issues in the Beta release, but I figure you'll want to know this.  In the listInterestGroupingAdd method, the listInterestGroupingAddOutput object returns an error, as follows:


response contains string value where integer expected [response]

   at CookComputing.XmlRpc.XmlRpcSerializer.ParseString(XmlNode node, Type ValueType, ParseStack parseStack, MappingAction mappingAction) etc. etc....


MailChimp's API says an integer should be returned from this method, but that doesn't appear to be the case.


Have you encountered this issue?


Thanks in advance for your help,

Argh! Thanks for finding this.

I must have missed testing this one with the xml-rpc request type in my rush to go on vacation and thought it was done when i came back. I tend to test serial/json & then go back to do xml-rpc afterward.

Unfortunately, this type of thing is all too common in the MC Api -- one of the many reasons I use intermediate result classes for the complex output methods is to try and isolate changes and other things not quite right in the documentation.

The never ending struggle between chaos & order -- or loosely & strictly typed languages.  PHP developers will never see this issue.

I don't want to do an intermediate results class for a simple value, so I'm going to submit this as an issue for MailChimp to resolve.

A work-around in the interim is to use a serial/json request meanwhile if you can do that.

Thanks again,

Thanks David for your quick response. 

The workaround will work fine in the meantime.  The good news is that the return value can be retrieved later through a call to listInterestGroupings, but the list is getting created in MailChimp, and that is the most important thing.

Jesse (The M.C. api guy) fixed this issue today -- So xml-rpc works fine for listInterestGroupingAdd() now.

Any update on b2? I'm looking at static segments and starting to think it makes a lot of sense for our project. Thanks and not trying to rush you at all, just curious!

Edit: Whoops! I see it here: http://perceptivemcapi.codeplex.com/releases/view/40074 I'll go take a look.
