It makes sense. I have added this to our dev version and it will be available when the next version of the Add-On is released. I haven't made any changes to it, so you can keep this line in your code and you should be OK when upgrading. </p> https://legacy.forums.gravityhelp.com/topic/hook-to-filter-initial-aim-transaction-before-arb-subscription-is-created#post-146384 Tue, 12 Feb 2013 22:28:28 +0000 Chris Hajer 146384@https://legacy.forums.gravityhelp.com/ <p>I'll bring this to the attention of the development team. </p> https://legacy.forums.gravityhelp.com/topic/hook-to-filter-initial-aim-transaction-before-arb-subscription-is-created#post-146320 Tue, 12 Feb 2013 17:35:20 +0000 tex77 146320@https://legacy.forums.gravityhelp.com/ <p>In the Authorize.net add-on, you have some hooks to filter the transaction/request before it's sent to the AuthNet api. </p> <p>make_product_payment() has gform_authorizenet_before_single_payment, which works for the AIM api. </p> <p>start_subscription() has gform_authorizenet_before_start_subscription, which works for the ARB api (for the subscription). </p> <p>But start_subscription() ALSO runs a preliminary AIM call -- get_initial_transaction(), which is NOT filtered by a hook! You do have a filter for if there's a Trial Period, but otherwise, not.</p> <p>I think it should be around line 1944:<br /> <pre><code>$transaction = apply_filters(&quot;gform_authorizenet_before_initial_transaction&quot;, $transaction, $form_data, $config, $form); $aim_response = $transaction-&gt;authorizeAndCapture();</code></pre>
