I have pored over the forum postings and information, tutorials, whathaveyou. There is so much conflicting information out there.

First: http://www.zen-cart.com/content.php?...payment-module

Says I need a PEM file. I call First Data and they are "Huh? Don't know what a PEM file is." Finally after being transferred around several times one person says, "I suppose we could give you a legacy file" then we got cut off.

Then I visit the First Data support for Zencart installation: https://firstdata.zendesk.com/entrie...n-Instructions

And there is no mention of a PEM file anywhere. They want me to make a Receipt Page. One of the links they reference is: http ://[ZENCARTFOLDER]/index.php?main_page=checkout_process&action=confirm

I check my ZC php files and the phrase "checkout_process" does not exist. Somewhere this phrase has to exist, right? (note spaces in my reference are to keep forum posting from making this a link)

Then I read in the forums about using Authorize.net SIM to make FirstData work.

Then something about making https ://mystore.com equivalent to http:mystore.com and needing several types of accounts with FirstData

Nowhere is there comprehensive, up-to-date information about FirstData, at least that is findable by yours truly.

So I'm hoping for some assistance...

Is there a document, FAQ, tips, notes, whatever that describes the current FirstData setup process?
Do I have the correct type of account? GGe4. Do I need another account?
Do I need to use the Authorizenet SIM module or the FirstData module?

I have an ecommerce ZC setup, v151, and am taking Paypal as my only form of payment. I would like to take credit cards where the customer types in their number and charges their card and eventually I get paid.

I have an SSL cert and curl is enabled.

thanks
