Instructions:
1. Carefully inspect all provided relevant files and context before making any code changes, focusing on:
   - Routes handling payment and checkout flows
   - Controllers managing payment logic and webhook processing
   - Payment gateway integration classes
   - Environment configurations related to payment credentials (ensure no secrets are exposed)
   - Application logs capturing payment errors or webhook failures
   - Database migrations affecting payment-related tables
   - Frontend checkout views and scripts

2. Identify the precise root cause of any bugs affecting checkout or webhook functionality.

3. Implement the smallest safe code change that resolves the identified issue, avoiding broad rewrites or risky modifications.

4. Ensure all existing payment gateway configurations remain intact and compatible.

5. Run syntax checks and all available automated tests to confirm no new errors or regressions.

6. Provide a detailed summary including:
   - Clear explanation of the root cause
   - List of all files modified with brief descriptions of changes
   - Exact code snippets added or modified
   - Verification steps performed and their outcomes
   - Recommended next actions or improvements, if any

Constraints:
- Do not expose or log any sensitive environment variables or secrets.
- Avoid broad or risky code rewrites.
- Maintain full compatibility with all existing payment gateways.

Before proceeding, confirm you have thoroughly inspected all relevant files and gathered sufficient context.

After completing the fix, deliver the summary and verification results clearly.

Replace all bracketed placeholders with your specific Laravel project details and payment bug context before running this prompt.

## Variables to Replace

1. Project context
2. Relevant payment-related files or code snippets
3. Recent error messages or logs
4. Current checkout or webhook behavior
5. Expected correct behavior
6. Constraints or special considerations
7. Environment details without secrets
8. Verification commands or tests
9. Definition of done

## How to Use

Replace every bracketed placeholder with your specific Laravel project details, payment-related files, error logs, current and expected behaviors, constraints, environment details (excluding secrets), verification commands, and definition of done before running the prompt. Use this prompt to guide Codex through inspecting, diagnosing, and safely fixing payment checkout or webhook bugs. Review Codex’s detailed summary and verification results carefully to ensure the fix meets your definition of done before deploying.

## Example Use Case

A Laravel SaaS platform experiences intermittent webhook failures causing payment status mismatches. The developer provides recent error logs, relevant controller and webhook route files, and environment details excluding secrets. Using this prompt, Codex inspects the codebase, identifies a missing webhook signature verification step, applies a minimal fix, runs tests, and summarizes the changes and verification results.
