Question

I tried to implement paypal pro for my site. Which will let user enter their info and charge 1$ for the trial, and 10$ for the recursive fee.

But when I check my merchant account, it show up 1$ and 10$ in separate order, but within 1 day (it charge 10$ that I don’t want)

Was there any problem with this query string?

Answer 1

I’m not too familiar with this part of the PayPal process (I still use IPN), but this line looks suspect:

&INITAMT=10

I believe that should be AMT.

From the PayPal Documentation:

INITAMT: Initial non-recurring payment
amount due immediately upon profile
creation. Use an initial amount for
enrolment or set-up fees

AMT: Billing amount for each billing
cycle during this payment period. This
amount does not include shipping and
tax amounts

So, by using INITAMT, you are charging them the $1 for the initial trial period plus a $10 enrollment fee. This does not sound like what you want.
