@Addo Sign Thanks for reaching out.
Have you reviewed this document to trigger your Timmer trigger function app and did you face any issue?
Please make sure that you are passing the x-functions-key
and Content-Type
as the Header in your request and not as query parameters. You could observe 403 issue if you are not passing the x-functions-key value correctly as header in your request. You need to pass _master
key of your function app. I have tested the same at my end and didn't face any issue.
