Azure APIM - Log All request and response headers

Question

Is there a way to log all the request and response headers in Azure APIM for all APIs? (at a global level)

Specifically log req and response headers for error cases

I tried the solution posted in https://learn.microsoft.com/en-us/answers/questions/418811/capture-header-parts-of-request-body-in-apim-log-a.html which is specific to each API

Do you need to list each and every header to be logged? Under "Headers to Log" section - i tried specifying a *, it doesnt seem to take effect.

@Nagashree Balasundaram Thanks for reaching out. If you want to log at the global level, then you need to specify the settings at the All API level as below.

• Navigate to "All APIs" (or the specific API if you wish to apply the logging setting at specific API scope)
• Click on "Settings"
• Click "Azure Monitor"
• Add the desired headers to 'Headers to log"
• Save

Any headers that are part of the incoming request can be logged in Log Analytics/Azure Monitor. Yes, you need to specify all headers that you want to be logged.
By Default: no headers are logged and * will not work. You can refer to this document for all the supported settings and their value types.

Feel free to get back to me if you need any assistance.
