Metadata api version.

Diksha Singh 60

I recently encountered a change in the behavior of the Azure Metadata service when trying to access the subscription ID using different version values. Initially, my code worked well with api-version=2021-06-01, but it stopped working. However, switching to api-version=2021-02-01 resolve the issue. I'm curious about the reasons behind this change and why different api-version values led to different outcomes.

Can you please share more detail or elaborate your ask to assist you better on this.

I see that the api version you have provided and mentioned that you code ran successfully is not in the supported list. The supported api version list was shared in the previous response.

Was that a typo in the initial question that you shared?

Now what basis does this API version get changed? Can this supported API version list be changed?

@Diksha Singh Thanks for your follow-up questions.

Based on my investigations, API versions are incremented when there are breaking changes in the API.

For example, renaming or removing endpoints, removing parameters or adding mandatory parameters, changing status codes, deleting a property in a response, or altering a response type at all.

When there is a new API version got published and the respective document will get updated by our content author team accordingly.

Feel free to reach back to me if you have any further questions on this.

@Diksha Singh Thanks for reaching out to Microsoft Q&A, apologize for any inconvenience caused on this.

Based on the shared information, I have understood that you are using the api version 2021-06-01 to pull the instance Metadata. But as per the current documentation we see that this particular API Version is not supported.

You can refer to this documentation for more information about the list of Supported API Versions of IMDS across different Azure Service like (Compute, Storage).

Feel free to reach back to me if you have any further questions on this.
