set_relationship with SOAP v2

[Steverino541]

I am working on using v2 for SOAP to set relationships between records in Leads and in a custom module called Insurancepolicy.

When doing this I am not sure if I can use set_relationship or if I have to use set_relationships.

Looking at the one called set_relationship it seems to me that I can only do this to records within the same module, is that correct?

Looking at set_relationships I cannot understand all the arguments that I am supposed to put in there. In particular I wonder about module_id, where do I obtain that? Shouldn't it be enough with module_name?

I am using C# for my development.

I am looking for some assistance :-)

Best regards,
Stefan

I now managed to get the code in C# working with set_relationship but it only works for the current default modules like Accounts to Contacts etc. When I try to set a relationship between leads and my own custom module I get a failure. Do I have to change the php files within my sugar installation some way?

Does using the v4 API make it work? This version has several .NET fixes which may resolve the problem.
