I'm not sure if you've understood the question.
What HTML code do I need to input to set the maximum failed attempts at recurring payments before the account is susspended please? You have these two usual ones:
<!-- Set recurring payments until canceled. -->
<input type="hidden" name="src" value="1">
<!-- PayPal reattempts failed recurring payments. -->
<input type="hidden" name="sra" value="1">
BUT, what is the line of code for this:
Setting the Number of Failed Payments
By including the optional MAXFAILEDPAYMENTS
parameter in the request to create a profile, you can set the number of failed scheduled payments allowed before PayPal deactivates (suspends) the profile. By default, the value is 0, which means no limit.
