What is also important: Does the "encID" even get passed through correctly?

Maybe do a little test survey with just one question (so you don't have to go through the whole thing to test).

Then create a entry link with the encID and see what the outcome of the END URL is.

Maybe you can attache this little survey as LSS file, so we can try to test.

However, in your situation I would not use passthru, but rather panel integration. This way, you have the encID saved in the database, which does not happen with passthru, as far as I know.

www.limesurvey.org/manual/URL_fields vs. www.limesurvey.org/manual/Panel_integration

Yes I did try your link survey.blablabla.com/?return=complete&encID={encID} but panel provider said it doesn't work and they told me to use
survey.blablabla.com/ic/survey.php?autoAnswer[317950][0]=0&encID={PASSTHRU:encID}

this is their complete link:
survey.blablabla.com/survey.php?autoAnswer [317950][0]=0&encID=xxx

Well, it works for me. See the attached sample survey:

Hi Tpartner,

Your LSS did not work for me. I did not receive a value for the encID in the end url.

However, when I looked into the panel integration, there was nothing set! Could you check if in your survey there is the encID set? Because this would mean, that the LSS export does not include the panel integration settings, which I would consider a bug.

So I included a encID in the panel integration settings and now the end URL presents the 12345.

However, no responses were saved in the database. This is really weird.

Thanks but I can not import your file... some internal web server error... but I followed your steps and I am not sure how you get this value 12345 at the end of the link?

My panel provider sent me end link like this
survey.blablabla.com/ic/survey.php?autoAnswer[317950][0]=0&encID={PASSTHRU:encID} ,
if I omit passthru how this link should be configured?

survey.blablabla.com/?return=complete&encID={encID} - now they are saying this one is working... I am confused

Really strange: I tried it several times in normal Chrome. No answer has been recorded, but I always reached the end url and it showed the correct encID. So then I pasted the link into a incognito window on Chrome and suddenly it worked. However, it added something at end of the URL:

www.google.com/?autoAnswer [317950][0]=0&encID=12345&gws_rd=ssl

Tried again in normal chrome, goes through the survey like a charm, but answer is not recorded in the response table.

Does LS prevent answers from a browser where you are logged in as admin???

Following my last message, here is a test file.

Thanks but I can not import your file... some internal web server error...

Then you have some problems with your installation.

The 12345 is the encID that Tpartner used for test. This needs to be part of the link the panel is sending their participants to.

Thanks but I can not import your file... some internal web server error...

So if this is your survey URL, it would look like this:

yourdomain.com/index.php/646657?lang=en&encID=XXXXX

So the different links would look like:
yourdomain.com/index.php/646657?lang=en&encID=00001
yourdomain.com/index.php/646657?lang=en&encID=00002
yourdomain.com/index.php/646657?lang=en&encID=00003

From this URL the panel integreation reads the encID into a hidden text question which is called "encID" and at the end URL this saved encID is retrieved and included into the end url your participants will be redirected to, so that the panel provider can register if they have completed. Same for the other links that they probably have provided you with for quota, screenouts, etc.

Tried again in normal chrome, goes through the survey like a charm, but answer is not recorded in the response table.

Logged out, tried again: response was registered.
Logged in again: response was registered.

Strange. Now it seems to work.

I never use panel integration, I just rely on this - www.limesurvey.org/manual/URL_fields/en#...using_GET_parameters .

I did use panel integration, but the manual gives only examples with passthru... so my panel provider followed it... now we omitted it but they still have a problem with their ID saving.... I do not know what it means, but it seems to me that is connected with the numbers at the end of the url encID=xxx

I am not sure that I am up to this Could you be so kind to take a look in my test file and to correct it?
