Unable to make POST connection using REST API

[Manish_Kumar_]

Hi,

I am trying to operate Qlik Nprinting using Qlik Sense. Reason is below

For that, I came through a Qlik Help video: https://youtu.be/FqwNU_pnFt4
And In this video there is reference to a pdf (is attached), which guides the complete process for making the GET and POST requests using REST API.

Now I successfully created GET connection following the procedure in the pdf document but I am having trouble in creating POST connection. Which is throwing below error.

Can anyone please suggest here!

Hard to say?  Reading the PDF, there seems to be a lot of reasons why it might fail:

Do you have REST connector 1.3 or higher?

Is Qlik and NPrinting running on the same machine?

Did you do this part:

"Under the “Query headers” section we inserted “Origin” as Name and the Qlik Sense server hostname as
value (the same hostname that we inserted in the NPrinting Trusted Origins); this is a requirement to
make the connection work using CORS."

Do you have the appropriate Administration account and an NT account as is specified?

Hi @Manish_Kumar_ 

I'm trying to do exactly the same than you. In my case, I noticed that in the article variable vCookie is obtained executing the sentence below:

let vCookie = TextBetween('$(vCookieRaw)','Secure,','Path=/',2);

In my case I had to use the next one:

Let vCookie = TextBetween('$(vCookieRaw)','SameSite=None,',' Path=/',2);

Now I have a different issue because when I executed the following code I receive an error:

Ah! depending of the Qlik Sense release you use, you can find issues with Rest Connector. In my case I'm using Qlik Sense May'2023 Patch 3 and I had to apply the workaround explained in the following link:

https://community.qlik.com/t5/Official-Support-Articles/Qlik-Sense-May-2023-Patch-3-causes-REST-conn...

If I find how to solve it I'll share it and if on the other hand, somebody had the same issue than us and fixed it, please let us know.

Thanks

Hi @Manish_Kumar_ , @daturpin 

I saw where was my mistake. I got a wrong value for vCookie:

• Instead of:

Let vCookie = TextBetween('$(vCookieRaw)','SameSite=None,',' Path=/',2);

• I'm using:

Let vCookie = TextBetween('$(vCookieRaw)','SameSite=None,',' Path=/',3);

Now it works.
