the "id" field here is the one I used

Yup - the first ID field. Thanks for the screenshot

thats what i mean - same as in the PUT call

not working : (

and your account ID is for your R2-enabled account?

It's not the same ID

yea i'm using the account id in the endpoint, not the access key id

i'm able to use r2 from the api, and worker bindings seem to work again too

weird

auth header is: AWS4-HMAC-SHA256 Credential=/20220422/world/s3/aws4_request, SignedHeaders=host;x-amz-content-sha256;x-amz-date, Signature=

Endpoint:

https://{account_id}.r2.cloudflarestorage.com

Access Key:

id

of the API Token Secret Key: sha256sum of the API Token --- Create an API token with the

Account

.

Workers R2 Storage

.

Edit

permission, you can also choose to allow all accounts or just one. After creating the token (you might want to do this in a new tab or copy your api token somewhere safe first), open devtools first then go to the API Tokens list page, find the

GET tokens?per_page=250

XHR request and view the response body. Under the

result

array find the token you created, and copy the

id

(should look like a UUIDv4 without any dashes).

id

will be your Access Key. To get the sha256sum of your token, I wrote the token to a new file,

.tmp

(in the format

CLOUDFLARE_API_TOKEN="{api_token}"

), ran

source .tmp

, then ran

echo -n "$CLOUDFLARE_API_TOKEN" | sha256sum | cut -f 1 -d " "

. This will be your Secret Key. (you may also want to also remove

.tmp

now and run

unset CLOUDFLARE_API_TOKEN

) For anyone having problems with sha256, make sure that you are not inputting a new line after your token (that's why I used echo with the

-n

flag) when passing it to sha256.

i had to create a new token! my existing one created earlier works for rest api (to create/delete buckets, push scripts with r2 bindings), but not s3 endpoint

thanks all

Oh nice! Glad you found it

So, i've never actually utilized an API on a command line before

where would I start

Which API?

Cloudflare's

I want to use it for R2

if you want to use the rest api, i would start with curl

I know but there's a few APIs

There's APIv4 (which powers the UI but the R2 endpoint is currently undocumented), there's Workers, and S3 compat

i have no clue what i'd want to use

What are you trying to do?

Create a bucket (R2) and store stuff in it

If you want to just start playing around with/building stuff with R2, take a look at the Sharex r2 example: https://github.com/Cherry/ShareX-R2-Cloudflare-Workers You have to use the Wrangler CLI to create buckets, but storing/etc should just be done with a worker

The R2 Docs have an example too, which details installing and setting up wrangler: https://developers.cloudflare.com/r2/get-started/

thanks!

nice
