Add access keys
Enter the R2 Access Key ID and Secret Access Key from the Cloudflare dashboard.
Test connection
CloudPairs validates the endpoint and bucket listing before saving.

Use R2 safely and efficiently
Common connection issues
Endpoint does not connect
Confirm the account ID and bucket name. If you typed a custom endpoint, compare it with the R2 dashboard format.

Check the R2 token permissions and whether it is scoped to the selected bucket.
