About this gig

Need to connect an API, webhook, CRM, website or custom app with n8n?


I will build and integrate your API or webhook automation in n8n so your systems can exchange data and trigger actions automatically.


I can help with:

  • n8n API integrations
  • REST API connections
  • Webhook automation
  • HTTP Request node setup
  • API authentication
  • OAuth integration
  • JSON data mapping
  • Data transformation
  • Custom API connections
  • CRM integrations
  • Google Sheets & Airtable APIs
  • Shopify and WooCommerce APIs
  • Slack, WhatsApp & email integrations
  • API error handling
  • Conditional routing
  • Custom JavaScript/Python logic
  • Fixing broken API workflows
  • Connecting apps without a native n8n node


If the application has an API or webhook, I can help connect it to your n8n workflow.


I can also troubleshoot existing n8n API workflows when requests fail, authentication breaks, data is mapped incorrectly, webhooks do not trigger, or the workflow returns errors.


You will receive a tested workflow and clear setup information where required.


I work with both n8n Cloud and self-hosted n8n.


Send me the API documentation, webhook information or a short description of what you want to connect & I will recommend the right integration.
