Pass-through

Paths continue from https://graph.microsoft.com/v1.0. Your Operate As key goes in Authorization; the client's access is added for you.

See Pass-through requests for the full request and response format.

Call any endpoint
curl "https://api.operate.as/v1/clients/6f1c2a7e-.../microsoft-bookings/..." \  -H "Authorization: Bearer $OPERATE_AS_API_KEY"
Response
{  "status": 200,  "data": {    "…": "the service's own response"  },  "encoding": "json"}

When access ends

Operate As renews the sign-in before it runs out and checks it daily. If Microsoft refuses to renew it, the service shows Expired, you're alerted, and your client reconnects from the same link.

See Keeping access alive and Removing access.
