Designing an EHR Integration Layer for a Telehealth Platform

·7 views

When developers hear “EHR integration,” the first thought is usually an API. But a production telehealth platform needs more than an API client. It needs an integration layer that can handle authentication, mapping, retries, errors, synchronization and external-system failures. A simplified architecture looks like: Patient App | v Telehealth API | v Integration Layer | +------> EHR | +------> Lab | +------> Pharmacy The integration layer should manage the authentication mechanism required by the target system. Don't spread EHR credentials and integration logic throughout the core application.

Getting Your First Orbistats API Key: A 5-Minute Quickstart Walkthrough

Most "quickstart" guides skip the part that actually trips people up: where exactly to click, what the key looks like, where to put it, and what the very first error message means when you get it wrong.

I Built a Bilingual Invoice-to-JSON API (Here Is the Whole Stack)

Every accounting team I talked to had the same problem: invoices arrive as PDFs and scans, and someone has to retype them into a spreadsheet. Existing OCR APIs are either expensive, English-only, or return a blob of text instead of structured data. So I built a small REST API that takes a document and returns JSON. You POST an image or PDF. You get back: { "vendor": "ACME Ltd", "date": "2026-09-14", "total": 1240.00, "currency": "USD", "line_items": [ {"desc": "Consulting", "qty": 4, "price": 310.00} ] } Bilingual out of the box: English and Vietnamese.

AWS Well-Architected Agent: Your Architecture Review, Now Done by an Agent (Preview)

A proper Well-Architected review has always had the same cost: a day or two of the team answering a long questionnaire, someone pulling evidence from five consoles, and a report that's stale within weeks. Trusted Advisor helps with point checks, but it has no idea which application matters or what your business is optimizing for this quarter. On October 1, 2026, AWS launched AWS Well-Architected Agent in public preview. It continuously analyzes your accounts and returns cost, security, resilience, and performance recommendations ranked against goals you write yourself, and it hands you the fix
