R2 REST APIS
Hello Team I need help. Im trying to upload a file using R2 REST APIS and not the SDK wrapper.... I have constructed the request headers and it matches my POSTMAN call (which works)... However on my browser the same endpoint returns a 403 for the prefilght OPTION request ... I have tried setting up CORS on R2 side of things but it doesn't allow the OPTION http method ...has anyone tried doing something like this

Are you using
api.cloudflare.com or r2.cloudflarestorage.com?here const url =
https://${accountid}.r2.cloudflarestorage.com/${r2bucket}/${objectKey};
@Erisa | Support EngineerWhats your CORS configuration in R2 side? OPTIONS should work if its configured correctly
At least, it does for presigned URLs afaik, I don't think its recommended to use the full S3 API in a browser
Since S3 will sign the method usually
[
{
"AllowedOrigins": [
"*"
],
"AllowedMethods": [
"GET",
"PUT",
"HEAD"
],
"AllowedHeaders": [
"Content-Type"
],
"ExposeHeaders": [],
"MaxAgeSeconds": 3600
}
]
i saw this onlinee..when i try to add the OPTIONS method i get a squiggly line beneath it

I cant use the SDK for my implementation .I want to directly call the APIS
isnt that possible
i tried using the POSTMAN Collection and it worked ...how do i achieve same in code
You need to use something to sign your requests with AWS SigV4, i.e aws4fetch
You can't just use the API token as-is
