About this Gig
Your apps do not talk to each other and you are losing time, leads, and revenue. Me and My team build secure API and webhook integrations that connect your CRM, payments, and SaaS tools automatically.
THE COST OF DISCONNECTED SYSTEMS:
- Hours lost to manual data entry every week
- Stripe or PayPal payments never reaching your CRM
- Webhooks failing silently with no alert
WHAT I DELIVER:
- REST API connections between any two business apps
- Real-time webhooks with Slack or Email failure alerts
- OAuth 2.0 authentication with token refresh
- Two-way CRM, payment, and database sync
- Custom Python or JavaScript when no connector exists
- Parallel testing before go-live so production never breaks
- Full documentation and Loom handover on Standard and Premium
I work with HubSpot, Stripe, PayPal, Shopify, GoHighLevel, Zoho, Airtable, n8n, Zapier, and any app with a public API.
Every integration includes error handling, live testing, and clear documentation. No silent failures.
Message me BEFORE ordering. I will confirm scope, timeline, and package free.
Tools: REST API, Webhooks, OAuth 2.0, Stripe, Python, JavaScript, n8n, Postman

FAQ
Can you connect two apps that have no native Zapier or Make integration?
Yes. That is my specialty. I build custom REST API and webhook connections using Python, JavaScript, or n8n when no out-of-the-box connector exists. If the app has a public API, I can connect it.
Do you handle OAuth 2.0 and secure API authentication?
Yes. I set up OAuth 2.0 flows, API key authentication, and token refresh logic so your integration stays connected long-term without manual re-authentication every few weeks.
Can you build Stripe or PayPal webhook integrations to my CRM?
Yes. I build payment webhook pipelines that send Stripe or PayPal events to HubSpot, GoHighLevel, Zoho, Google Sheets, Slack, or any CRM in real time with error alerts if a payment event fails to sync.
Will your integration break my live system when you deploy it?
No. I always test in parallel before touching production. You get a rollback plan, confirmation testing, and error alerts so nothing goes live untested.
What is the difference between your Basic, Standard, and Premium packages?
Basic connects 2 apps with 1 API flow. Standard adds multi-app integration, OAuth, two-way sync, and 7-day support. Premium is a full system integration with custom code, monitoring, handover call, and 30-day support.
What do I need to provide before we start the API integration?
API documentation or developer access, list of apps involved, and a clear description of what data should move where. If you are unsure, message me first and I will map your integration architecture free.
Can you fix a broken webhook or API connection that stopped working?
Yes. Broken webhooks and expired OAuth tokens are common fixes. For full audit and repair of existing automations, see my Zapier and Power Automate fix gig. Many clients start with a fix and upgrade to a full API build.
Do you provide documentation after the integration is complete?
Yes. Every package includes written documentation. Standard adds an API map diagram and Loom walkthrough. Premium includes a full runbook and live handover call so your team can manage the integration independently.
