We use Key Vault extensively in our solutions, to store any secrets we might need. For example in an API through code, in Azure Functions via the application settings, or in a Logic App through a REST call. If you go to your secrets in Key Vault, you will notice that the link to the secret includes a version number, in the format of https://kv-we-retrieve-kv-secret.vault.azure.net/secrets/MySecretValue/80df3e46ffcd4f1cb187f79905e9a1e8.
Of course, this is great if we want to reference a specific version of a secret. However, often we will just want to reference the latest version, so we stay up to date even when the secret has been changed, for example because it is a rotating password.
It turns out, this is very easy, without the need to update the version number in all our applications whenever a new version is created. This is done by just omitting the version number from our link! So the will instead look like https://kv-we-retrieve-kv-secret.vault.azure.net/secrets/MySecretValue/.
Important to notice is the trailing slash ( / ), which needs to be included, otherwise you will just get a 404 error.
