Ipn? url

Hi downloaded your plugin and intalled, everything went fine until checkout, clicked on pay with pesapal and it didn’t transfer to pesapal and gave this message: Problem: parameter_absent | Advice: > oauth_parameters_absent | oauth_consumer_key&oauth_signature_method&oauth_signature&oauth_timestamp&oauth_nonce
[ps: I have entered the consumer and secret key in woocommerce admin]

I then realised I hadn’t put in the Ipn details on the pesapal site, but not sure what it means by ipn listener url and what that should be. PLEASE Help

I also don’t understand what you mean by.
‘<?php do_action(‘plugin_name_hook’); ?>’
is it name = your plugin name and by template do you mean in the theme file somewhere???

Ps I am not a coder but a designer, i use wp cos for the most part you only have to use a bit of css, so forgive my ignorance.
