How to add subIDs to the link?

When selecting checkbox “add subIDs”, you will see 4 fields for subIDs:

Open

You can add up to 4 different parameters in the tracking link. The available parameters are p1, p2, p3 and p4: we recommend appending publisher's Click ID and other parameters in these fields.

Enter the parameters that you would like to pass and click Update:

Open

The tracking link will be updated with the subIDs:

Please make sure the syntax in the link is correct: the symbol right after the slug must be “?” and then followed by the parameter for subID p1, the next symbol before the second parameter must be “&”, same goes before the third and fourth parameter.
