If your development team uses AI coding assistants (Claude Code, OpenAI Codex, Cursor, and others), you can speed up your SimPay integration by adding a ready-made Agent Skill to your repository — a context file that gives your assistant accurate knowledge of our API instead of it guessing field names or the authorization scheme.
The skill isn't tied to a single tool — it works with any agent that can load a Markdown file as context.
- Authorization (API key, base URL, required headers)
- Creating a payment (
directChannel, an example request/response, the most common mistakes that trigger antifraud rejection) - Payment method values, and transaction / refund / subscription statuses
- Refunds
- IPN notifications: payload structure, signature verification (SHA-256, with a PHP example), retry behavior, dynamic IP validation
- Brief pointers to BLIK Level 0 / One-Click / Recurrent Payments, DirectBilling (DCB), deferred payments (PayPo, Twisto, BLIK Pay Later), and SMS Premium
- List of official SDKs
- A pre-launch checklist
# Claude Code
git clone https://github.com/SimPaypl/simpay-ai-skill .claude/skills/simpay-api-integration
# Codex / other agents following the same convention
git clone https://github.com/SimPaypl/simpay-ai-skill <your-skills-dir>/simpay-api-integrationOr via the skills.sh CLI:
npx skills add SimPaypl/simpay-ai-skillRepository: github.com/SimPaypl/simpay-ai-skill
The skill is maintained by hand against this documentation. If you notice something is out of date, open an issue or PR in the repository.
