SOAP API - Unable to get lead using Cookie?
I'm trying to get Anonymous Lead through the SOAP API. This would be the source code within XML's body:
'<mkt:paramsGetLeadActivity>',
'<leadKey>',
'<keyType>COOKIE</keyType>',
'<keyValue>id:XXX-XXX-XXX&token:_mch-domain.com-1533412128399-11111</keyValue>',
'</leadKey>',
'<startPosition>',
'<latestCreatedAt />',
'<offset />',
'</startPosition>',
'<batchSize>10</batchSize>',
'</mkt:paramsGetLeadActivity>',
The resulting error is Lead does not exist, which is not true, because it is possible to obtain the Anonymous Lead using Marketo ID ('IDNUM' keyType, as documented at http://developers.marketo.com/soap-api/leads/getlead/).
Is this bug or feature? If it's intentional, is there any other way how to obtain Marketo ID from a Cookie? (Using SOAP, JS, REST, Munchkin etc.)
Thank you for your help, Joe
