If you’re facing issues with API Lab, you can try the following steps to resolve them.

​
Connectivity

If API Lab fails to send your request, it could be because you may be experiencing connectivity issues. Check your connection by attempting to open a page in your web browser.

​
Firewalls

Sometimes firewalls may be configured to block non-browser connections. You might need to contact your network administrator so that API Lab can work seamlessly.

​
Incorrect protocol

You might have specified the wrong protocol, check if you’re using https:// or http:// in your URL or vice-versa.

​
API Lab errors

It could also be possible that API Lab might be making invalid requests to your API server. You can confirm this by checking your server logs (if available). If you believe this is happening, do get in touch with the API Lab team.

​
CORS restrictions

CORS or Cross-Origin Resource Sharing is a security mechanism built into modern web browsers. It may cause the following error when testing API endpoints or some other API endpoints with API Lab. This is because the API not sending the proper API headers (Access-Control-Allow-Origin) and can be solved in two ways.
  1. Ask whoever manages the API to add CORS support.
  2. Use Middleware like ProxyScotch for hosted APIs & the API Lab Browser Extension for locally served APIs, and enable it in the “Interceptor” section of “Settings”.
