No Traces in Azure API Response
The Flag Ocp-Apim-Trace
has been set to true
.
Ocp-Apim-Trace
true
The API Response displays this information under the Trace Tab:
Trace location was not specified in the response or trace log is not
available.
Yet no traces are available. How does one resolve this?

To enable trace, you need to include "Ocp-Apim-Trace" and "Ocp-Apim-Subscription-Key" in request header.
If the API does not require subscription, you can still get admin subscription key in developer portal. This enforce that only admin can get tracing log. To get admin subscription key if you are an admin, go to Developer Portal -> Profile -> find your target API and copy the key.
The Ocp-Apim-Trace feature enables you to specify whether or not APIM should generate a trace file on blob storage.
Setting the header to 'true' within Postman for example, will give you back a HTTP Header in the response called Ocp-Apim-Trace-Location.
This will contain the URL to your trace file, which you can open in any browser.
You might want to install a plugin/extension to be able to format JSON files properly in order to make it easy to read.
Just putting
Ocp-Apim-Trace
into postman does not,( maybe for me and how my APIM is setup), return any such http location. Is there setup required in Azure to return such a location?– ΩmegaMan

Ocp-Apim-Trace
@ΩmegaMan you need to have an administrator subscription key to see the trace files being returned. Sorry for not mentioning this earlier.

Just setting the flag Ocp-Apim-Trace to true will not suffice.
One needs to set the subscription key as well as per this doc.
https://docs.microsoft.com/en-us/azure/api-management/api-management-advanced-policies#Trace
So, for API's which do not have a subscription key, not sure how one can get the traces
Mark this as the answer, which is ok to do, to close the issue.
