Some improvements:
- querying the terminal for guides, checking if the terminal has all the guides required by the application, logging into the terminal with common terminal and application guides.
- defining one hTIM_CFG variable for all TIM-API parameters
- purchase transactions support
- credit transactions support
- cancel transactions support
- receipt request support
- cash advance support (terminal must support "Advanced Retail" guide)
- support for reversal transactions (purchase and credit)
- balance support
- code reorganization
- error handling

Hi George. I am wondering about the need to configure the integration ID. Does this mean that you need a unique identifier from Worldline to be able to operate Worldline payment terminals? Without it, the terminal will not work at all? You provide any internet addresses: test and production, so you have to go through some process of validation of the correctness of communication between POS and EFT? Where this address is configured? Worldline certifies the software that works with their terminals?

Hi Edward

First of all, I would like to thank you, without your help I would not have moved on.

I didn't hear from you for a few days, I was waiting for support.
After 3 days of setup, initialization and "wise advice", the payment terminal went through ACTIVATE
A problem arose again, I could not go through the authorization of the payment card. I received a set of different types of payment cards for testing, the system rejected them all.
Answer from support
"There are some issues with our test host environment and none of transactions are accepted.
We are checking it from time to time and hope that it will run soon. "

And so I wait...

To your questions:
The integration ID is only used in communication, it is not entered directly into the payment terminal
It is the data in your section it is a 32 digit code in five blocks

Of the IP addresses, only the first one is entered into the terminal during initialization
1 Software download 153.46.253.140:8953 HTTP tserv.ep2.telekurs.com

I assume that the terminal will take care of the rest, only the specified ip addresses must be available

Yes, I have to go through the validation process.
After the implementation of the integration, I have to fill out the document, the verification phase will begin.

Tomorrow (today, it's already morning) I'll try your new features.
The way I look at them, I will need them all

I will let you know the experience with the real terminal, I'm just afraid that I won't move further until I pass the verification of the credit card.

Georg

I started converting the code into a class. What other features do you think will be needed?

Hi Edward

Thank you for your efforts.

I'm sure I'll forget something important

ta_card_track_data_get_track_number @143

these are functions from timapi.def

some data I don't even know what they are for

Card verification should already work, but I'll get to that on Saturday.
I will test it using AdvancedEcr.exe and your new functions and let you know what values are actually returned. These should be sufficient for records.

The return value would be an array.

Creation of the log file for the transaction

By trasaction I mean one case from Connect to Disconnect
Parameters - filename with path, append mode
Someone may want to save the log on a daily basis and then need append.
I personally prefer individual files, name -'document number'+'.tim'

Print transaction confirmation

Payment terminals are supplied in two versions
-with a printer
-without a printer

I have a terminal without printers at my disposal. My application must ensure printing on the cash register printer.
In Slovakia, it's similar to Poland, we have mandatory fiscal printers, so I print it on it after completing the cashier's receipt.

I don't know how it will turn out if I send the transaction to a payment terminal with a printer, whether it will automatically print it.
The return would be an array and individual rows.

I hope that we will reach a successful end.
It should help everyone who creates applications for stores.



Regards, George

The information you have indicated to be obtained can now be read from the hash table of card information. When asking about features, I meant other types of payments, e.g. mobile payments using a phone and a code and/or NFC. BLIK mobile payments are very popular in Poland. I don't know how they could be implemented using the TIM API. Could you ask WorldLine Support whether and how to make such a BLIK payment?

Hi Edward

Thank you for the clarification.
Of course I will ask. I am sending the given questions to Wordline.

Georg

I am uploading the TIMAPI class with an example of use.
I also added new features. I am not attaching the description yet (there is no time to develop it) but I have included comments in the code. I think they will be helpful.

Great job !

Hello Edward

Thanks for the great work.

During testing, a problem arises with the TIM_CardInfo method
After attaching or inserting a payment card into the reader, it will display an error

I am also attaching the LOG file that was created so far
your_filename.zip

I solved it so far by creating an empty method with the given name


The transaction then proceeded correctly.
I am attaching a screenshot.

Log file after confirming the transaction
your_filenameok.zip

I am also testing other functions.

"Configurate"
has the effect of switching the terminal language to English

I don't know if it would be possible to set the terminal language in the "Initialize" function.
Function in timapi.def
ta_terminal_get_supported_languages @554
ta_terminal_change_language_for_request @505
