Add Cloudflare R2 Account

Cloudflare R2 Setup

These steps need to be completed within the Cloudflare dashboard.

Sign in to the Cloudflare dashboard
Select your account, then navigate to R2 Object Storage in the left sidebar
Create a bucket if one does not already exist. Note the bucket name.
Navigate to R2 Object Storage > Manage R2 API Tokens
Select Create API Token
Give the token a name, select the bucket(s) it should have access to, and choose Object Read & Write permissions
Select Create API Token
Copy the Access Key ID and Secret Access Key. Save both for the PlaidCloud Document setup below. The secret is only shown once.
Note the S3 API endpoint for your account. It follows the pattern https://{account_id}.r2.cloudflarestorage.com and is shown on the R2 overview page.

You should now have everything you need to add your Cloudflare R2 account to PlaidCloud Document.

Sign into PlaidCloud
Select the workspace that the new Document account will reside
Go to Document > Manage Accounts
Select the + New Account button
Select Cloudflare R2 as the Service Type
Fill in a name and description
Enter the Start Path as your R2 endpoint followed by the bucket name: https://{account_id}.r2.cloudflarestorage.com/my-bucket
The Region field can be set to auto or left blank — R2 automatically selects the closest region
Select an appropriate Security Model for your use case. Leave it Private if unsure.
Paste the Access Key ID into the Access Key ID field under Auth Credentials
Paste the Secret Access Key into the Secret Access Key field under Auth Credentials
Select the Save button and your new Document account is live
