Connecting
Your client presses Connect on their link and approves on Zoho's own screen. Operate As never sees their password.
curl https://api.operate.as/v1/me/clients \ -H "Authorization: Bearer $OPERATE_AS_API_KEY"[ { "id": "6f1c2a7e-...", "name": "Miller Dental", "services": [ "zoho-sign" ] }]Permissions
| What the client reads | Permission it asks for |

Pass-through
Zoho Sign has no ready-made tools yet. Call any endpoint of its API through Operate As instead, with the client's access attached.
Add the client
In Clients, add your client and select Zoho Sign. Then send them their link.
Your client connects
They sign in with Zoho and approve.
Find the endpoint
Pick the call from Zoho's own API docs. Your path is everything after https://sign.zoho.com/api/v1.
Send it through Operate As
Use the client's ID, the service key zoho-sign and that path. 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.
curl "https://api.operate.as/v1/clients/6f1c2a7e-.../zoho-sign/requests" \ -H "Authorization: Bearer $OPERATE_AS_API_KEY"{ "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 Zoho 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.
