TL DR: No CORS is not supported by Īs I answered in #99, we do not provide the CORS headers necessary to use clientside js to directly make requests to the api.īoth of the comments cited above are from a Yelp engineer. So using or similar in your frontend code would allow you make requests to the Yelp API cross-origin from your frontend code.Ī related issue in the GitHub issue tracker for the Yelp API examples repo confirms no CORS: This cause of the problem is that doesn’t support CORS.Īnd there’s nothing you can in your own application code to fix that-no matter what you try, you can’t change the fact that doesn’t support CORS.Īpparently the Yelp API does support JSONP though see for example Yelp API Origin is not allowed by Access-Control-Allow-Origin. Would this still be possible given my environment? Any guidance as to which direction I should go and clarification of my misconceptions would be greatly appreciated.Īgain, thank you for your help for a growing developer.
Is this an issue due to the syntax of my header with Yelp Fusion's OAUTH2 token requirements, do I need to do something proxy-related, or is the reason because of something else? If proxy-related, currently I am running a fully client-driven application and do not use server-side code at all. The following is how I call the fetch in my code: var options = ( Response for preflight has invalid HTTP status code 500 Any attempts I make seem incorrect and do not result in a change.).Īs a side note: I have installed the Allow-Control-Allow-Origin: * extension on my Chrome browser, but I receive the same error - just a shortened, less elaborate description of it:įetch API cannot load.
Using yelp api how to#
(Answers that seem particularly helpful are: Response to preflight request doesn't pass access control check and API Request with HTTP Authorization Header inside of componentDidMount, but I do not really understand how to actually implement those solutions with my environment. I have done a lot of searching to see what responses to identical issues already exist, but I am left even more confused in how to tackle my problem with my relatively new knowledge to this kind of development environment. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
Origin ' is therefore not allowed access. I have a small application that attempts to make an async GET request from Yelp Fusion's API using 'isomorphic-fetch', but receive the following error:įetch API cannot load Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
