I’m using zapier to connect some other systems with infusionsoft, and I get this error message on Zapier:
‘Fault (code 0) occurred. Message: Failed to invoke method addToGroup in class com.infusionsoft.api.xmlrpc.XmlRpcContactService: contactId must be a valid id’
This only happens when I want to update fields in Infusionsoft, I also use Infusionsoft as my trigger and on those cases, I don’t get that error.
Can you guys help me with this? I don’t know how to fix this.
