Integrate Sag with OpenClaw by building a skill that calls Sag’s public APIs and/or accepts Sag webhooks, registering and configuring that skill in ClawHub (providing OAuth client credentials or API keys as secrets), keeping long‑running/stateful pieces outside the agent runtime (webhook receiver, token refresh, databases, schedulers), and ensuring every API call is authenticated and validated (token scopes, webhook signatures, TLS). Implement an external HTTP service that the OpenClaw skill invokes (or that calls into OpenClaw when webhooks arrive), store secrets in ClawHub/your secret store, and use standard debugging steps (logs, API responses, credentials/scopes, and ClawHub invocation logs) when things fail.

The error means the value you gave to clawctl configure-token is not the exact, usable API token the OpenClaw runtime expects — common causes are a mistyped/truncated token, wrong token type (UI/session token vs agent/API token), an expired or revoked token, or clawctl pointing at a different OpenClaw instance where the token is invalid.
2
The Operator doesn't auto-create OpenClawFlow CRDs because either the CRD isn't installed/applied, the operator lacks RBAC/cluster permissions, the connector manifest only creates CR instances (not CRD definitions), or there's an apiVersion/Kind/namespace mismatch—OpenClaw requires explicit CRD installation and correct permissions.
kubectl get crds | grep OpenClawFlowkubectl -n openclaw-operator logs deploy/openclaw-operator and inspect ServiceAccount/ClusterRoleBindings3
Webhook TLS handshakes fail because the ocl-agent cannot build a trusted TLS connection to Sag’s endpoint: common causes are an untrusted or expired certificate chain, hostname/SNI mismatch, TLS version/cipher incompatibility, Sag requiring mutual TLS (client cert) or the agent/container lacking the needed CA roots or being behind TLS‑inspecting proxy.

Direct answer: Sag events are rejected with schema version mismatch because the event's serialized schema version (what the producer embedded or the sink expects) does not match the version registered in the OpenClaw Schema Registry for the subject the sink connector is validating against.
Common causes:
Check the event's schema version vs registry and ensure the connector's subject and converter settings align. Example guard in a consumer/transform:
```javascript // // parse incoming Sag event and compare versions const evt = JSON.parse(raw); if (evt.schemaVersion !== process.env.EXPECTED_SCHEMA_VERSION) { throw new Error('schema version mismatch'); } ```This prompt helps an AI assistant understand your setup and guide you through the fix step by step, without assuming technical knowledge.
