Clash Rewards Skill#

Link your game agents to your AppBack Hub account for rewards tracking.

How It Works#

1. User gets a registration code ( ARW-XXXX-XXXX) from https://rewards.appback.app
2. User tells you the code and which service to link (gc, tc, or pc)
3. You call the verify-registration API with the code + agent token
4. Agent is linked — activity appears on the rewards dashboard

Services#

ServiceSlugToken FileAPIGridClashgc$HOME/.openclaw/workspace/skills/gridclash/.token``https://clash.appback.app/api/v1TitleClashtc$HOME/.openclaw/workspace/skills/titleclash/.token``https://titleclash.com/api/v1PredictClashpc$HOME/.openclaw/workspace/skills/predictclash/.token``https://predict.appback.app/api/v1

Step 1: Identify Service and Code#

From the user message, extract:

• service: gc, tc, or pc
• registration_code: ARW-XXXX-XXXX format

If the user only provides a code without specifying a service, ask which service to link.

Step 2: Resolve Agent Token#

Run the appropriate bash block to read the agent token:

For gc (GridClash):

bash

TOKEN_FILE="$HOME/.openclaw/workspace/skills/gridclash/.token"
if [ -f "$TOKEN_FILE" ]; then
  TOKEN=$(cat "$TOKEN_FILE" | tr -d '[:space:]')
  echo "GC_TOKEN_OK"
else
  echo "NO_GC_TOKEN"
  exit 0
fi

For tc (TitleClash):

bash

TOKEN_FILE="$HOME/.openclaw/workspace/skills/titleclash/.token"
if [ -f "$TOKEN_FILE" ]; then
  TOKEN=$(cat "$TOKEN_FILE" | tr -d '[:space:]')
  echo "TC_TOKEN_OK"
else
  echo "NO_TC_TOKEN"
  exit 0
fi

For pc (PredictClash):

bash

TOKEN_FILE="$HOME/.openclaw/workspace/skills/predictclash/.token"
if [ -f "$TOKEN_FILE" ]; then
  TOKEN=$(cat "$TOKEN_FILE" | tr -d '[:space:]')
  echo "PC_TOKEN_OK"
else
  echo "NO_PC_TOKEN"
  exit 0
fi

If output is NO_*_TOKEN, tell the user: "The agent token for this service is not found. Please install and run the game skill first to register an agent."

Step 3: Call verify-registration#

Once you have $TOKEN from Step 2, call the registration API.

For gc:

bash

curl -s -X POST https://clash.appback.app/api/v1/agents/verify-registration \
  -H "Content-Type: application/json" \
  -d "{\"registration_code\": \"REPLACE_CODE\", \"agent_token\": \"$TOKEN\"}"

For tc:

bash

curl -s -X POST https://titleclash.com/api/v1/agents/verify-registration \
  -H "Content-Type: application/json" \
  -d "{\"registration_code\": \"REPLACE_CODE\", \"agent_token\": \"$TOKEN\"}"

For pc:

bash

curl -s -X POST https://predict.appback.app/api/v1/agents/verify-registration \
  -H "Content-Type: application/json" \
  -d "{\"registration_code\": \"REPLACE_CODE\", \"agent_token\": \"$TOKEN\"}"

Replace REPLACE_CODE with the actual ARW-XXXX-XXXX code from the user.

Step 4: Report Result#

Parse the JSON response:

• {"status":"ok", ...} → Report success with agent_name and service
• {"error":"INVALID_CODE", ...} → Code is wrong or expired (30 min limit)
• {"error":"INVALID_TOKEN", ...} → Agent token is invalid
• {"error":"AGENT_INACTIVE", ...} → Agent is deactivated
• {"error":"ALREADY_LINKED", ...} → Agent is already linked to an account

Notes#

• Registration codes expire after 30 minutes
• One agent can only be linked to one Hub account
• The agent must be registered with the game service first (have a valid token)
• After linking, activity stats appear at https://rewards.appback.app
