Passthrough Data

AnswerSoft · Member

I seem to have a knack for finding information just after I post something out here.

I think the following link may answer my question:

https://secure.ifbyphone.com/developers.php?a=netget

However, if you want to offer any tips in addition to what is mentioned here, I'd appreciate it. I'm learning "on the job" as I produce this app.

For now, I'm calling it a night and will try to squeeze in some time to look at it tomorrow.

Thanks.

Mike,

Passthrough data is absolutely the way to go. We don't use it for any processing, we just take it in at the beginning of the Survo and pass it back as part of the NetGet. A couple pointers:

Passthrough data (p_t) can change every time you do a NetGet. That is, if your code is gathering more information as the call progresses, you can add information to p_t each time you do a NetGet.

Secondly, you can add multiple key\value pairs by delimiting them with |. If you wanted to get a user_id and a pin, you could use the following p_t: user_id|1234||pin\9876, where the single bar separates the key from the value, and the double bar delineates the pairs.

So, just how do you assign values to the passthrough data? When looking at the net integration screen I see that "passthrough data" is one of the drop downs I can choose as the parameter type. Let's say that in a webservice I get a dollar amount, as I described above. In the first webservice call, I returned it in a user parameter called amtowed. Let's say the value was $124.56. Can you tell me the steps necessary to take that value and pass it as passthrough data to my credit card processing webservice? I understand the whole parameter1|value||parameter2|value thing. But I'm thinking that that comes into play when I am building the return xml while in the webservice. In my net integration definition section inside my SurVo, how do I get the value of

amtowed|124.56||ccnote|"This is a note"

into the passthrough parameter? I keep hitting brick walls when I try this. Then when I call the next webservice, does it get passed in as this type of string so that I would need to parse it out in order to get the correct value?

Maybe if you could point to an example of passthrough data being used sucessfully, that may help.

Thanks,

Mike

Mike,

On your first webservice you'll be echoing back XML to redirect the call. That is where you add in the pass through. So for example, your XML is going to look something like this:

<app>SurVo</app>

<user_parameters>

<param1>value1</param1>

<param2>value2</param2>

</user_parameters>

<p_t>mypassthrough data</p_t>

</parameters>

</action>

Where the pass through is set between the and tag. Note that you should probably avoid the double quotes. I *think* the spaces should work, but you should test. Remember the pass through will show up in a URL (for the next NetGet), so all data must be URL compatible.

If this doesn't answer your questions, PM me and we can set up a call if you like.

Please why you guys create webservice in XML, I hate it because I can't understand what happening in there !

It's actually not a bad way to do things. XML gives you a common communication format so that your source is not language dependent.
