About this gig
Is your Power Automate flow failing because of an HTTP request, REST API, custom connector, authentication, or permission error?
API and connector issues can stop data from reaching your apps, return unauthorized responses, or cause an entire business workflow to fail.
I will troubleshoot and fix Power Automate HTTP REST API integrations, custom connectors, authentication, and permission errors so your flow communicates correctly with external services.
I can help with:
Power Automate HTTP actions
REST API integration
GET, POST, PUT, PATCH and DELETE requests
Custom connector setup and fixes
API authentication
OAuth and token issues
400, 401, 403, 404 and 500 errors
Headers, parameters and request bodies
JSON request and response handling
Permission and access errors
Connection reference issues
API response troubleshooting
Dynamic content and expressions
Webhook integration
Failed flow debugging
Existing API workflow optimization
I will trace the failed request, identify the integration issue, correct the configuration, and test the flow against your expected result.
Message me with your API or connector issue before ordering.
