Bing Web Search API doesn't accept percent-encoded commas in URL

Question

According to this documentation page of the Bing Web Search API:

Remember that you need to URL-encode all query parameters, so the parameter actually looks like:

`&responseFilter=webpages%2Cnews`

But when I did that, the search API returned this error:

$ curl "https://api.bing.microsoft.com/v7.0/search?q=aluminium&responseFilter=news%2Cwebpages"

{"_type": "ErrorResponse", "errors": [{"_type": "Error", "code": "InsufficientAuthorization", "message": "Insufficient authorization to access requested resource.", "moreDetails":"Only these values are allowed: Webpages,Images,Videos,News,SpellSuggestions,entities,places,RelatedSearches,Computation,TimeZone,Translations", "parameter": "responseFilter", "value": "news%2Cwebpages" }]}

Why is this the case?

Hi @Minh Duc Pham

Thak you for using the Microsoft Q&A forum.

Based on my experience, I tried to reproduce the issue and found a solution to be specifying the responseFilter parameter without percent-encoding.

I suggest you try using the responseFilter parameter without percent-encoding, as I did in below repro.

curl "https://api.bing.microsoft.com/v7.0/search?q=aluminium&responseFilter=News,Webpages" -H "Ocp-Apim-Subscription-Key: YOUR_SUBSCRIPTION_KEY"

Part of the Output:

This should resolve the issue and allow you to use multiple values for the responseFilter parameter.
