I will build n8n API integration and webhook automation for business


Level 1
About this gig
Your apps have APIs but nothing is wired in n8n yet, so your team still copies data by hand. I build n8n workflows with REST API integration, webhooks, and OAuth so your CRM, payments, and tools sync automatically.
WHY N8N PLUS API:
- Connect apps Zapier cannot link natively
- Self-host option saves cost at scale
- Custom Python or JavaScript inside the same workflow
- Full control over HTTP requests, auth, and retries
WHAT I BUILD IN N8N:
- REST API and webhook integrations between any two systems
- OAuth 2.0 and API key authentication with token refresh
- Stripe, PayPal, HubSpot, Shopify, GoHighLevel, Zoho, Airtable
- Two-way sync, data mapping, filters, and error handling
- Dedicated n8n error workflow with Slack or Email alerts
- Parallel testing before go-live
YOU GET:
Clear documentation, workflow diagram, and Loom handthrough on Standard and Premium.
Message me BEFORE ordering. Send your API docs or app names. I will confirm scope and package free.
Tools: n8n, REST API, Webhooks, OAuth 2.0, Python, JavaScript, Postman, Stripe

FAQ
Why use n8n for API integration instead of only Zapier?
n8n lets you run custom HTTP requests, JavaScript, and Python in one workflow, self-host for lower cost, and handle complex API logic Zapier often cannot. I use n8n when you need reliable API integration without platform limits.
Can you connect apps that have no ready-made n8n node?
Yes. I use the HTTP Request node, webhooks, and code nodes to connect any app with a public REST API or webhook documentation.
Do you setup OAuth 2.0 in n8n workflows?
Yes. I configure OAuth credentials in n8n, handle token refresh, and test auth before connecting live data flows.
Can you integrate Stripe or PayPal webhooks in n8n?
Yes. Payment webhooks trigger n8n workflows that update your CRM, send emails, log to Google Sheets, and alert Slack when a payment succeeds or fails.
Will you break my live system when you deploy the n8n workflow?
No. I test with sample payloads in parallel, use n8n error workflows, and only switch live traffic after you approve test results.
Do I need n8n Cloud or can you setup self-hosted n8n?
Both work. n8n Cloud is faster to start. Self-hosted on a VPS costs less long term. I can deploy self-hosted n8n as a gig extra with Docker and SSL.
