Creating a Token

Note: Cloudflare R2 tokens will enable access to all buckets. At the time of writing it is not possible to scope the token to a given bucket. If this is not ok for you it might be worth it to consider another bucket provider.

Now that you have your bucket all setup. Next we will need to generate the S3 compatible token. Head back to the R2 dashboard in your account. Look for the Manage R2 API Tokens.

Find the Create API Token link.

Once you see the Create API token form go ahead and fill it out. You can name the token to something like instellar r2 so you know that this token is used by instellar.

Also make sure you enable Edit permission. Set the TTL of the token to what you feel is appropriate but do remind yourself that you have to replace this token at some point.
