Description
Integrate Merso PNPL (Play Now, Pay Later) payments into games or digital goods platforms. Use when a user wants to: (1) add Merso installment payments to a...
Usage Guidance
This is a coherent integration guide for Merso and does not request unrelated access. Before installing or using it: (1) treat MERSO_API_KEY as a sensitive secret — never expose it to client-side code and store tokens securely; (2) confirm with Merso the exact webhook signing header and secret (the doc uses MERSO_API_KEY as an example HMAC key — verify this); (3) restrict webhook endpoints (HTTPS, IP allowlist if no signature) and implement idempotent handlers as instructed; (4) test fully in the development base URL (api2.dev.merso.io) before production; (5) be aware the commercial docs make product claims (zero KYC, license expiry model) that you should validate with legal/compliance for your region. The skill is instruction-only, so it itself will not install code or fetch remote binaries.
Capability Analysis
Type: OpenClaw Skill
Name: merso-integration
Version: 1.0.5
The skill bundle provides comprehensive documentation and instructions for integrating the Merso PNPL (Play Now, Pay Later) payment platform. It contains standard API references (api2.merso.io), webhook security implementation examples using HMAC-SHA256, and commercial context in SKILL.md and the references/ directory. No evidence of data exfiltration, malicious execution, or prompt injection was found.
Capability Assessment
Purpose & Capability
Name/description (Merso PNPL integration) match the declared requirements (MERSO_ENV, MERSO_GAME_ID, MERSO_API_KEY) and the included reference docs describe API endpoints, webhooks, DB schema and integration flow that a merchant would need.
Instruction Scope
SKILL.md and references provide concrete integration steps (auth, token caching, POST /merso-buy-item, webhook setup/verification, fallback verify endpoint) which are appropriate. Note: it advises caching/auto-renewing tokens and gives a webhook verification example using MERSO_API_KEY as an HMAC secret — valid but implementers should securely store tokens and confirm the actual webhook signing scheme with Merso before trusting production traffic.
Install Mechanism
Instruction-only skill with no install spec and no code files — minimal surface area and nothing is written to disk by the skill itself.
Credentials
Only three environment variables are required and they are directly relevant to a payment integration: environment, game ID, and API key. No unrelated credentials or broad system config are requested.
Persistence & Privilege
Skill is not always-enabled, is user-invocable, and has no install/runtime components that request persistent system-level privileges or modify other skills' configurations.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install merso-integration - After installation, invoke the skill by name or use
/merso-integration - Provide required inputs per the skill's parameter spec and get structured output
