I wanted a chat agent that could pull security alerts from Sophos Central on demand. Type "get Sophos alerts" into a Copilot Studio chat, get back a readable answer. No dashboard, no manual API calls. It works now, end to end. Agent calls a Power Automate flow, the flow talks to the Sophos API, and the response comes back formatted in chat. This post is how I got there, including the bugs that ate most of my time. The shape of the thing Three pieces: A Copilot Studio agent that the user talks to A Power Automate flow that does the actual API work The Sophos Central API on the other end The agent does not call Sophos directly. It calls the flow, the flow handles auth and the request, and the result gets passed back to the agent to format. Keeping the API logic in the flow means the agent stays simple. The flow The flow is named Sophos - Get Alerts , living in a solution called Sophos Integration . Here is the structure: [Trigger: When Copilot Studio calls a flow] | [Init ClientId] - String (Sophos Client ID) [Init ClientSecret] - String (Sophos Client Secret) [Init TenantId] - String (your Sophos tenant ID) [Init ApiHost] - https://api-<region>.central.sophos.com | [HTTP Get Token] POST https://id.sophos.com/api/v2/oauth2/token Header: Content-Type: application/x-www-form-urlencoded Body: grant_type=client_credentials&client_id={ClientId}&client_secret={ClientSecret}&scope=token | [Parse Token] - extract access_token | [HTTP Get Alerts] GET {ApiHost}/common/v1/alerts Headers: Authorization: Bearer {access_token} X-Tenant-ID: {TenantId} Accept: application/json | [Return value(s) to PVA: AlertsResponse = body('HTTP_Get_Alerts')] Auth is OAuth client credentials. You request a token, then use it as a bearer token on the alerts call. The tenant ID goes in an X-Tenant-ID header, not the URL. Where the credentials live This is the part people will have opinions about, so let me be upfront. The Sophos client ID, secret, and tenant ID are stored as flow-scoped variables wit
