Frequently Asked Questions
What if the API doesn't have documentation?
I can reverse-engineer APIs using browser developer tools and network analysis. Additional research time may be required.
Can you work with legacy SOAP APIs?
Yes! While I specialize in REST, I can integrate with SOAP and XML-based APIs as well.
Do you handle authentication?
Yes, I handle all authentication types: API keys, Basic Auth, OAuth 1.0/2.0, JWT tokens, and custom authentication schemes.
What platforms do you support?
N8N, Zapier, Make, Power Automate, and custom Node.js/Python scripts.

Orders finally synced
We needed a reliable connector between our Shopify store, a legacy OMS, and our warehouse system. AHK.AI set up OAuth, handled token refresh, and built pagination so we could backfill 18 months of orders without timeouts. The retry logic and rate-limit handling stopped the random “missing order” issues we’d been chasing. They also added monitoring with clear alerts, so we know when a webhook fails instead of finding out from customers.
Project: Shopify + OMS + WMS integration with webhook intake, backfill via paginated REST, and monitoring/alerts

Clean, testable integration
Our product needed to ingest usage events from a partner API that was poorly documented. AHK.AI reverse-engineered the endpoints, documented assumptions, and shipped a connector with solid unit tests and mocks. They implemented JWT auth, automatic refresh, and idempotency keys to prevent duplicate billing events. The data transformation layer was especially well done—everything lands normalized in our Postgres schema with predictable field mappings.
Project: Partner usage-event ingestion (REST) into Postgres with JWT auth, idempotency, and test coverage

HIPAA-minded execution
We integrated a patient intake platform with our scheduling and EHR-adjacent system. AHK.AI was careful about PHI handling, audit logs, and least-privilege scopes in OAuth. They built retries with exponential backoff and a dead-letter queue so failed payloads don’t disappear. Minor delay on the final documentation handoff, but the connector has been stable and the monitoring dashboard makes compliance reviews easier.

Leads routed instantly
Our brokerage runs leads from multiple listing portals into a CRM and a dialer. The problem was messy JSON and frequent 429 rate limits. AHK.AI built a middleware service that parses and enriches lead records, manages rate limiting, and retries safely. They also added a “replay” tool so we can resend failed webhooks during busy weekends. We stopped losing leads and our agents noticed immediately.

Solid integration, some tweaks
We connected our accounting system to a payments platform and needed strong error handling around chargebacks and settlement reports. AHK.AI delivered a robust integration with pagination for large report pulls and clear retry policies. We did have to iterate on a couple of edge cases where the provider sent inconsistent currency fields, but they addressed it quickly and added extra validation. Overall dependable and well secured.
Project: Payments platform to accounting sync including settlement report ingestion, chargeback events, and validation rules

Reporting made painless
We pull campaign performance from Meta, Google Ads, and a niche DSP into a single dashboard. AHK.AI built connectors that handle pagination, token refresh, and throttling without us babysitting scripts. They also normalized fields (UTM params, campaign IDs, attribution windows) so our analysts aren’t doing spreadsheet gymnastics. The monitoring alerts are clutch—if an API changes, we know fast and can react before client reports go out.
Project: Multi-ad-platform data pipeline into BI dashboard with OAuth refresh, throttling, and normalized metrics

ERP data stays accurate
We needed to sync inventory and production orders between a cloud MES and an on-prem ERP. The APIs were finicky and occasionally dropped connections mid-page. AHK.AI implemented resilient pagination, retries, and a checkpointing approach so large sync jobs can resume safely. Their transformation layer mapped units of measure and lot numbers correctly, which is critical for traceability. The only reason it’s not a full 5 is a longer-than-expected QA cycle on our side.
Project: MES-to-ERP integration for inventory, work orders, and lot traceability with resumable sync and transformations

Client-ready deliverables
As a consulting firm, we needed an integration we could hand off to a client’s internal dev team without drama. AHK.AI delivered clean code, thorough documentation, and tests that actually cover the tricky bits (auth refresh, retry policies, and pagination). They even annotated the reverse-engineered endpoints and provided a runbook for monitoring and incident response. The handoff was smooth, and the client’s engineers were impressed.

Roster sync works
We integrated our LMS with a student information system to automate rostering and grade passback. AHK.AI handled OAuth setup, built a reliable sync with retry logic, and mapped course sections and enrollments cleanly. They also implemented safeguards so accidental deletes don’t cascade—huge relief for our admins. We requested a few extra fields late in the project (accommodations flags), and they accommodated without breaking the existing mappings.

Tracking updates never miss
Our 3PL sends shipment status through webhooks, but we were missing scans during peak volume. AHK.AI built a hardened webhook receiver with signature verification, queueing, and replay. They added retry logic for downstream API calls into our TMS and implemented rate-limit management so bursts don’t cause 429 failures. The monitoring is practical: we get alerts with payload IDs and timestamps, making investigations quick.
