This page may have been moved, renamed, or deleted. ## Suggested Pages You may be looking for one of the following: - [SecureFields JS](https://docs.payengine.co/developer-docs/processing-payments/secure-fields.md) - [Hosted Payments](https://docs.payengine.co/developer-docs/processing-payments/hosted-payments.md) - [5a. Securing Embedded UIs Using HMAC (deprecated)](https://docs.payengine.co/developer-docs/getting-started-1/securing-embedded-uis-merchant-session/securing-embeddable-uis.md) - [6. Loading the frontend library](https://docs.payengine.co/developer-docs/getting-started-1/frontend-frameworks.md) - [1. Creating User Accounts](https://docs.payengine.co/developer-docs/getting-started-1/getting-started.md) ## How to find the correct page If the exact page cannot be found, you can still retrieve the information using the documentation query interface. ### Option 1 — Ask a question (recommended) Perform an HTTP GET request on the documentation index with the `ask` parameter: ``` GET https://docs.payengine.co/developer-docs/processing-payments/secure-fields.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. ### Option 2 — Browse the documentation index Full index: https://docs.payengine.co/developer-docs/sitemap.md Use this to discover valid page paths or navigate the documentation structure. ### Option 3 — Retrieve the full documentation corpus Full export: https://docs.payengine.co/developer-docs/llms-full.txt Use this to access all content at once and perform your own parsing or retrieval. It will be more expensive. ## Tips for requesting documentation Prefer `.md` URLs for structured content, append `.md` to URLs (e.g., `/developer-docs/processing-payments/secure-fields.md`). You may also use `Accept: text/markdown` header for content negotiation.
