Good day to you.

In general, the software allows you to insert a specific HTML code that is usually provided by the society which handles the payment process that needs to be inserted as displayed in the screenshot:

By proceeding this way, a specific button generated by the provided code should be displayed to the user at the end of the order process.

If any additional code needs to be added, the Expert section at Step 1 -> SEO, Analytics and Code is the best place where to do this.

Unfortunately, all of the code needs to be provided along with detailed instructions on how to integrate it by the previously mentioned company, and the Staff can offer no specific support for each type of custom code.

Should you encounter any particular issue while integrating this, I'd suggest contacting the company's tech support directly and then eventually report the information here in order to see if there is something we can do about it

I hope I was clear enough, but let me know if I can provide further information on this to you

Thank you for your understanding

Stefano
