POST Request Body

[ipazin]

hi there @graeme_morrell,

welcome to KNIME Community!

So you are trying to build a POST request in some kind of a loop? I assume you are using flow variables for that purpose as well? If so topic where String Manipulation was used to build a complex query can help:

String manipulation ambiguous return type in SPARQL query

Hi I’m trying to build a SPARQL query using String Manipulation (Variable) Node. In input it gets flow variable data from a table, it should replace item column with the desired query, but I get only ‘ambiguous return type’ error [image]

Br,
