The way developers build with open banking has evolved rapidly in recent years. AI coding tools are becoming a standard part of engineering workflows. Technical teams are now able to evaluate infrastructure partners more rigorously, so expectations around clarity, structure and speed are higher than ever.
The quality of API documentation plays a central role in this experience. It shapes how quickly teams can understand a platform, assess its capabilities, and move from evaluation to integration.
We rebuilt ours with this idea in mind.
Today, we’re launching the new Yapily documentation site at docs.yapily.com. This rebuild is designed around how engineering and product teams work today, and how businesses assess infrastructure providers with AI coding tools at their disposal.
A structure that reflects real integration journeys
As our platform has expanded, our documentation has grown in volume and complexity. While the information remained comprehensive, navigating it was not always straightforward.
Our new Docs site structure separates learning, building, and reference into clearer pathways:
Learn: Foundational concepts, authorisation flows, and context on how open banking works in practice.
Build: Integration guides and step-by-step instructions to implement payments, data access, and VRP.
API Reference: Detailed endpoint documentation, request and response schemas, and parameter definitions.
Payments and Data: Clearly segmented by product areas so you can navigate directly to your relevant use case.
This update mirrors how teams approach open banking integration. Engineers can now move directly into integration guides and schema definitions, and product and technical leads can evaluate coverage and integration flows without sifting through raw endpoint documentation.
The result is less friction for your team across both technical discovery and implementation.
Built with agentic coding in mind
Tools from companies such as Anthropic, Cursor, and Windsurf are increasingly embedded into engineers’ day-to-day operations.
This means documentation now needs to be structured and consistent enough to be interpreted accurately by AI systems, not just by humans. When an AI coding assistant pulls context from your docs, formatting inconsistencies or ambiguous field descriptions can lead to incorrect output.
Our new documentation has been designed with this in mind. We standardised schema formatting, clarified parameter definitions, and simplified hierarchy, so AI tools can interpret our content more reliably.
As a result, developers using agentic tools will see better code completions, more accurate code generation, and fewer hallucinated API calls. This shortens integration cycles and reduces support queries, particularly for teams using agentic workflows.
Embedded AI support
We have also embedded an AI support assistant directly within the documentation experience.
This is grounded in our API reference and guides, so responses are tied to actual source material. Instead of manually searching across multiple pages, developers can ask a natural language question and receive a contextual answer linked to the relevant documentation.
For engineering teams, this reduces feedback latency during development, while for businesses conducting technical due diligence, it accelerates evaluation.
And as always, our support team remains available when direct assistance is required.
An updated Learn section
The Learn section has been fully rewritten to provide a clearer foundation for understanding the platform.
It now includes structured guides on:
Open banking fundamentals
Step-by-step explanation of authorisation flows
Payment types and country nuances
How Yapily fits within the broader payments ecosystem
Teams that are new to open banking can now follow a logical starting path. Experienced teams can quickly and easily find the implementation details relevant to their use case.
The goal is not to simplify the content, but to make it easier to navigate for differing levels of expertise.
Clearer navigation and change visibility
Beyond structural reorganisation, we also focused heavily on findability and change visibility.
The search function has been improved so naming conventions are consistent. Product areas are now clearly segmented, and technical leads can assess domestic payments, international payments, VRP, hosted pages, and data access without piecing together information from unrelated sections.
We have also introduced a new feature:
Changelog: Every API update, bank integration, feature release and breaking change is documented in a single, dated location. We've enhanced our Changelog with new features, including RSS capabilities for easy subscription and filters to quickly find relevant updates. For regulated businesses, this new visibility and structure directly supports internal change management and compliance tracking.
What this means for existing integrations
If you are already integrated with Yapily, nothing in your implementation will change or our APIs have not changed. This is a structural and usability improvement, not a product shift.
If you are evaluating open banking providers, the new documentation makes it easier to assess both our technical capabilities and our approach to infrastructure design.
Explore the new documentation for yourself
If you’re new to open banking, start with our Open Banking 101 guide to understand the fundamentals and how Yapily fits into the ecosystem.
If you’re ready to build, jump straight to the API Reference or the relevant integration guides for payments, data, or VRP.
You can subscribe to the RSS feed to stay informed when new documentation is published, guides are updated, or integration details change.
Or, ask our embedded AI assistant your first question directly within the documentation.
As documentation should evolve alongside the ecosystem it supports, we welcome feedback from engineers, architects and product teams. Leave your feedback here.
