Execute Queries Dax REST API for Direct Lake over OneLake – real examples?

[jaryszek]

Hi all,

I’m using Direct Lake over OneLake and trying to run DAX queries via the executeQueries REST API.

I’m not looking for docs — only real, working REST examples.

Looking for someone who has actually done this to share:

• The exact REST endpoint used for executeQueries

• Headers (auth + content-type)

• The exact JSON body that worked (simple DAX like EVALUATE TOPN(10, Table))

• How you authenticated:

  • Service principal or user

  • Required API permissions and workspace role

• Which semantic model ID you targeted for Direct Lake over OneLake

Even sanitized Postman or curl examples would help a lot.

Thanks!

Hi @jaryszek,

I’d suggest checking the documentation linked below. It explains the exact REST endpoint, required headers, and sample JSON requests, which should help you verify your setup and troubleshoot the issue.

Since you’re specifically looking for real, working examples, it would also be helpful if other community members who have done this recently could share their hands-on experience. Let’s wait and see if anyone else can add more practical examples or insights.

Thanks & Regards,
