Help Please: CONVERSION_PRECEDES_CLICK

[Joey Belarmino]

I've already searched the forum about this issue but couldn't find a solution. 

Issue:

Uploading of offline conversions result to an error CONVERSION_PRECEDES_CLICK.

We have already followed the documentation on how to handle the converstionTime properly, with the timezone Id and we did convert it also to the adwords account's timezone.

We compared the data between the manual upload (csv) (successful) we did before against the data we are trying to upload via API just to make sure that we are really uploading the right data. But turned out the data are the same but uploading via API always return the CONVERSION_PRECEDES_CLICK for most of the data. 

Here's an example:

GCLID, value, conversiontime 

CPzg5pHUzsECFRFgfgod0AIAYA,2.06,20141027 235255 America/Denver

Please can you please help us solve this issue. Its been days already that we are stuck on this.

Thank you!
