Hello All, I'm about to pull my hair out dealing with this pixel. This is the information CJ has given me. The OID (order ID) is a unique alphanumeric ID that needs to be generated on your end, and will be assigned to each unique transaction that occurs. If the OID is not unique, meaning if our system detects a duplicate OID for another transaction, the second transaction will be ignored, which is why it is important that unique OIDs are generated for each transaction (in your case, for each lead form that is completed and submitted) and What I would suggest doing for your OID, is hardcoding a time and date stamp into the pixel to act as the OID. When you do this, you must exclude any symbols (colons, slashes, periods, etc) from the time/date stamp, and have the time be recorded all the way down to the millisecond. Since it will be extremely rare (if it happens at all) that two transactions will occur within the same millisecond, it will create a unique number to act as the OID for each lead that is submitted. I have no idea what this means or how to do it. Here's an example of a pixel. /u?CID=1520654&OID=InvoiceIDxyz&TYPE=344815&IT EM1=lead&AMT1=0&QTY1=1&CURRENCY=USD& METHOD=IMG" height="1" width="20"> Someone please help, I am at my wits end.
