SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill addresses the complexity of managing diverse financial provider webhooks by enforcing a strict, thin-transport architecture that prevents business logic bloat and ensures high availability.

Core Features & Use Cases

  • Thin Transport Pattern: Decouples HTTP request handling from business logic, ensuring rapid response times required by providers like Stripe and Plaid.
  • Standardized Verification: Provides a consistent contract for signature verification and error handling, preventing transient bugs from triggering provider retries.
  • Workflow Integration: Seamlessly dispatches events to durable workflows, ensuring idempotency and reliable state synchronization across financial services.

Quick Start

Use the Cobalt Webhooks skill to implement a new provider handler by creating a thin transport route that verifies the signature and dispatches the event to a workflow.

FAQPage Schema
How do I standardize financial webhook handlers for multiple data providers?

Standardize financial webhook handlers by enforcing a thin transport pattern that decouples HTTP request handling from business logic. This architecture verifies signatures and dispatches events to workflows, preventing logic bloat and ensuring rapid response times for providers.

What is the thin transport pattern for webhook processing?

The thin transport pattern for webhook processing decouples HTTP request handling from business logic to ensure rapid response times. It separates transport, signature verification, and workflow dispatch into distinct layers to maintain high system availability.

How do I verify signatures for Plaid and SnapTrade webhooks consistently?

Verify signatures for Plaid and SnapTrade webhooks consistently by applying a standardized verification contract across all financial data providers. This prevents transient bugs from triggering unnecessary provider retries and ensures reliable integration.

How do I ensure idempotent processing for incoming financial webhooks?

Ensure idempotent processing for incoming financial webhooks by dispatching verified events to durable workflows. This workflow integration guarantees reliable state synchronization across financial services and prevents duplicate processing of the same event.

Can I use this webhook architecture for App Store and Plaid integrations in a monorepo?

You can use this webhook architecture for App Store and Plaid integrations within a monorepo environment. It standardizes the implementation of HTTP webhook handlers across diverse external services by enforcing strict separation of concerns.

Why do financial webhook providers retry requests and how can I prevent it?

Financial webhook providers retry requests when endpoints respond slowly or return errors. Prevent retries by implementing a thin transport layer with standardized signature verification and error handling, ensuring rapid response times and preventing transient bugs.
