Problem with post request using qlik rest connector

[RdeHarder]

Hello all,

I am trying to POST a request to a server using the available Rest connector, I have my POST request working in Curl and Postman but I can not get it to work in Qlik.

I have the following simple Curl request:

curl --request POST "https://api.ctbps.nl/v3/OAuth/Token" -d "grant_type=client_credentials"

This returns the following error:  {"error":"unauthorized","error_description":"The client is unknown."} which is good.

However when I try to recreate this POST request in Qlik, configured as follows:

I get the following error:

I have also tried to use the query parameters to pass the grant_type but this resulted in the same invalid request error.

Can you tell me what I am doing wrong!

Many thanks in advance.

Hi,

Try configure your REST connector as follows:

• Add a request header
  • Name: Content-Type
  • Value: application/x-www-form-urlencoded
• Request body: grant_type=client_credentials
