Hi Kaniz, Thank you for your answer
"ensure you authenticate using a personal access token (PAT) and include it as the `Bearer` token in your request headers."
Wher can I generate my PAT and where is the Bearer token in my request header ? 

Do you have an example of a request that returns a successful run ?

"/api/2.0/jobs/runs/submit" : I took this from the documentation I linked but unfortunately there was no complete example

"provide the correct job ID and settings in your request data." I changed the job ID when I linked my code with the databricks instance to be safe, but in my initial code it was correct.

I don't have any setting in my job configuration, it's all default, I just use the cluster from my databricks instance, it should work right ?

"double-check your authentication setup and ensure that your access token has the necessary permissions to trigger the job." Where can I check this please ? 

Thanks in advance for your answers and your time
