Not really. I don't have access.
- Do you have an error log
- how did you integrate this?
- are there dupes?
Thanks for replying. Well, I couldn't find any error log until now. It's just a important difference between Marketo's records and our website's records - I have almost 70% more leads recorded in our Drupal plataform. I have already disconsider the dupes when I calculated the difference.
We integrated it using API. Do you think that API is not delivering all the leads?
Which API? Marketo has multiple API endpoints that could be used for this (although only the client-side Forms API should really be used as a best practice).
You'll need to provide thorough technical insight into your code. We can't possibly have knowledge of what you're doing on the app side which is 99% likely the cause of the error. There's no reason to believe successful API calls are not upserting data into Marketo. If you're exceeding rate limits, though, you won't get success responses. But without more info we can't help.
