Query Graphql with download tool

GloriousWater

Hi. I'm trying to query Tableau's Graphql API through the download tool with the following payload.
It works (pic 1), and returns a list of workbooks. The problem arises when I want to add a filter to the query (pic2):

Pic(1):

Pic(2):

I cannot for the world figure out how to add the filters correctly. The query, with filter, runs fine directly in the Graphiql browser editor (pic3).

Pic(3):

In Alteryx the query needs to be written as a json object.

Please help We are going nuts over this.

Finally figured this out! The way the string is passed via JSON doesn't work with the double quotes. You need to add backslashes like the below example (which reads in a list of projects to call for).

'{
"query": "query workbookFields {workbooks(filter: {projectName:\"'+[ProjectName]+'\"}) {name,projectName,embeddedDatasources {fields {name,isHidden,__typename},upstreamTables {name,schema,database{id,name,luid,connectionType},upstreamDatabases{name}}}}}"
}'
