What you get with this Offer
Build custom API calls inside n8n, allowing you to connect virtually any external service through HTTP Request nodes or authenticated APIs.
Whether it’s a private CRM, a 3rd-party analytics platform, or any RESTful service, I’ll create and test the custom API logic, handle authentication (OAuth2, API Key, etc.), and format the response for downstream nodes in your workflow.
What you get:
1) Custom HTTP Request setup
2) Authentication (Bearer, Basic, API Key, OAuth2)
3) Error handling and retries
4) JSON parsing and formatting
5) Integration with other services (Google Sheets, Slack, Airtable, etc.)
