On our websitre, we have a registration form to give access to the resource library. That system is capuring lead in the website DB to manage access to the library.
We have developped a Web Service that push every hour the leads from the Website DB to Marketo using the SOAP API. This is working fine.
We now want to associate the lead that completes the form to the Marketo Cookie and track behavior properly.
In order to do so, we used the Munchkin API to capture the forms data and push it to Marketo directly.
We did some test and it looks like it was working properly.
In order to validate, we compared the list of leads created in Marketo by the Munckin API with the list of leads added via the Web Service API.
For some reasons that I can't explain, some leads are not picked up by the Muncnkin API and they get added later by the Web Service. (see the screen shot below).
Does anyone have ideas where I should be looking to figure out why some leads are not captured by The munckin API?
Also, on a side note, any idea why the Lead ID is significantly different depending on the source?
