# 403 Error on Gravity Forms Callback

 * I’m using Gravity Forms along with Stripe to process payments. Strip is saying
   the callback url ([https://winterstreetdesign.com/?callback=gravityformsstripe](https://winterstreetdesign.com/?callback=gravityformsstripe))
   returns a 403 error. I think Wordfence is blocking it, though when I go there
   it loads fine.
 * I tried adding a rule to the whitelisted urld for the firewall. This is what 
   I entered:
    URL: / Parameter: request.queryString[callback]
 * Does that look right? and does it seem possible that it is Wordfence?
 * Thanks.

 * Hi [@winterstreet](https://wordpress.org/support/users/winterstreet/),
 * It could indeed be Wordfence.
 * Could you please:
    - _Go to “Wordfence –> Live Traffic”_
    - Select the “_Blocked by Firewall_” filter
 * Does the request you mentioned appear there? If so, you can choose to whitelist
   this action by clicking the “_[Whitelist Param from Firewall](https://docs.wordfence.com/en/Web_Application_Firewall_-_How_to_use_Learning_Mode#What_to_do_if_a_page_is_blocked_after_Learning_Mode_is_complete)_”

 * Thanks for getting back to me, and I should’ve updated this thread, but I figured
   it out. I whitelisted the url, ran a test transaction, and Stripe sent me an 
   email right away telling me that it was working.
