The OpenClaw Gateway's agent method has strict parameter validation that rejects unknown properties. The paperclip property was being sent at the root level of agentParams, causing validation failures with error: "invalid agent params: at root: unexpected property 'paperclip'" The paperclip metadata is already included in the message field via wakeText, so removing the separate paperclip property resolves the validation error while preserving the necessary information.

OpenClaw Gateway Adapter
This document describes how @paperclipai/adapter-openclaw-gateway invokes OpenClaw over the Gateway protocol.
Transport
This adapter always uses WebSocket gateway transport.
- URL must be
ws://orwss:// - Connect flow follows gateway protocol:
- receive
connect.challenge - send
req connect(protocol/client/auth/device payload) - send
req agent - wait for completion via
req agent.wait - stream
event agentframes into Paperclip logs/transcript parsing
Auth Modes
Gateway credentials can be provided in any of these ways:
authToken/tokenin adapter configheaders.x-openclaw-tokenheaders.x-openclaw-auth(legacy)password(shared password mode)
When a token is present and authorization header is missing, the adapter derives Authorization: Bearer <token>.
Device Auth
By default the adapter sends a signed device payload in connect params.
- set
disableDeviceAuth=trueto omit device signing - set
devicePrivateKeyPemto pin a stable signing key - without
devicePrivateKeyPem, the adapter generates an ephemeral Ed25519 keypair per run - when
autoPairOnFirstConnectis enabled (default), the adapter handles one initialpairing requiredby callingdevice.pair.list+device.pair.approveover shared auth, then retries once.
Session Strategy
The adapter supports the same session routing model as HTTP OpenClaw mode:
sessionKeyStrategy=issue|fixed|runsessionKeyis used when strategy isfixed
Resolved session key is sent as agent.sessionKey.
Payload Mapping
The agent request is built as:
- required fields:
message(wake text plus optionalpayloadTemplate.message/payloadTemplate.textprefix)idempotencyKey(PapercliprunId)sessionKey(resolved strategy)
- optional additions:
- all
payloadTemplatefields merged in agentIdfrom config if set and not already in template
- all
Timeouts
timeoutSeccontrols adapter-level request budgetwaitTimeoutMscontrolsagent.wait.timeoutMs
If agent.wait returns timeout, adapter returns openclaw_gateway_wait_timeout.
Log Format
Structured gateway event logs use:
[openclaw-gateway] ...for lifecycle/system logs[openclaw-gateway:event] run=<id> stream=<stream> data=<json>forevent agentframes
UI/CLI parsers consume these lines to render transcript updates.
