Operations 6

Each operation below carries the questions people ask an LLM about it and the instructions they give an agent to run it. Generated by API Evangelist overlay

GET /subscriptions/{subscriptionId}/providers/Microsoft.Web/certificates List certificates in a subscription · Get all certificates for a subscription #
Ask an LLM
“Which App Service certificates exist across my whole Azure subscription?”
“Can I filter my subscription's certificates, for example by key vault reference?”
Tell an agent
List every App Service certificate in my subscription.
List subscription certificates matching filter {filter}.
GET /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Web/certificates List certificates in a resource group · Get all certificates in a resource group #
Ask an LLM
“What certificates are stored in one particular resource group?”
“Can I narrow the certificate list down to a single resource group?”
Tell an agent
List the certificates in my current resource group.
Show only resource-group certificates, not the whole subscription.
GET /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Web/certificates/{name} Get a certificate · Get a certificate #
Ask an LLM
“When does one of my App Service certificates expire, and what hostnames does it cover?”
“Can I look up a single certificate by its name?”
Tell an agent
Get certificate {name}.
Show the thumbprint and expiry of certificate {name}.
PUT /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Web/certificates/{name} Upload or replace a certificate · Create or update a certificate #
Ask an LLM
“How do I upload a TLS certificate for my function apps and web apps?”
“Can I create a certificate resource or fully replace an existing one in one call?”
Tell an agent
Create certificate {name} with properties {properties}.
Upload a new certificate named {name}, overwriting any existing definition.
PATCH /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Web/certificates/{name} Patch an existing certificate · Create or update a certificate #
Ask an LLM
“Can I change just some properties of an existing certificate without re-uploading it?”
“Is there a partial update for an App Service certificate?”
Tell an agent
Patch certificate {name} with {properties}.
Partially update the existing certificate {name}.
DELETE /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Web/certificates/{name} Delete a certificate · Delete a certificate #
Ask an LLM
“Can I remove an expired certificate I no longer use?”
“What happens to bindings when I delete an App Service certificate?”
Tell an agent destructive · confirm first
Delete certificate {name}.
Remove the unused certificate {name} from my resource group.
