Documented steps
Deploy Connect with its two required images, 1password/connect-api (REST API) and 1password/connect-sync (syncs with 1Password.com), using the 1password-credentials.json produced during Secrets Automation setup.
Create an access token for the Connect server in the 1Password.com dashboard or with op connect token create, and store it securely - it is shown once.
Export it for tooling: export OP_API_TOKEN=<token>. (The op CLI instead expects OP_CONNECT_HOST and OP_CONNECT_TOKEN.)
Check reachability: curl https://<connect-host>:8080/heartbeat and curl https://<connect-host>:8080/health
List vaults to obtain UUIDs: curl -H "Authorization: Bearer $OP_API_TOKEN" -H "Content-type: application/json" https://<connect-host>:8080/v1/vaults
List items in a vault: GET /v1/vaults/{vaultUUID}/items with the same headers.
Get full item detail including sections and fields: GET /v1/vaults/{vaultUUID}/items/{itemUUID}. The list endpoint omits sections and fields, so a second call is required.
For attachments: GET /v1/vaults/{vaultUUID}/items/{itemUUID}/files then GET /v1/vaults/{vaultUUID}/items/{itemUUID}/files/{fileUUID}/content
Audit usage with GET /v1/activity.
To reuse the same server from the CLI, set OP_CONNECT_HOST and OP_CONNECT_TOKEN; op read, op run, op inject and op item get then route through Connect instead of 1Password.com.

Known gotchas
A Connect token is scoped to specific vaults at creation, so the API returns only what that token was granted - an empty /v1/vaults result usually means token scope, not a server fault.
The item list endpoint deliberately excludes sections and fields; fetching values requires the per-item GET, which doubles the call count on bulk reads.
Item write endpoints (POST/PUT/PATCH under /v1/vaults/{vaultUUID}/items) require write access; a read-only token is rejected.
OP_CONNECT_HOST / OP_CONNECT_TOKEN take precedence over OP_SERVICE_ACCOUNT_TOKEN in the same shell, so mixing the two auth models causes silent misrouting.
Connect is self-hosted infrastructure you must keep online and patched; it is a separate component from both 1Password.com and Service Accounts.
