How to set up your personal s3 bucket for use with

Your s3 bucket is your own personal destination for cloud storage.

If you already have an AWS account and would like us to set your bucket, we only charge $20. Contact us here.

NOTE: You must be using a paid subscription to to use a personal s3 bucket. Click here to subscribe.


First, we need to create a bucket for your files.

Click create bucket.
  • Name your bucket according to AWS’s naming policy. Anyone who get links to your files will see your bucket name, so pick something that makes sense for your use case.
  • Select a region for your bucket. Pick the region that is closest to you or the people who will be using the files in your bucket.
Select the name and region for your bucket.
  • Set your default privacy. If you are planning on permanently sharing at least some files, uncheck the “Block all public access” checkmark. If you’re planning on keeping all your files private unless you grant temporary access to individual files, leave the box checked. You can change this later if you’re not sure, so don’t dwell on it.
For buckets that can share at least some of their files openly, set your checkboxes like this.
  • Set default encryption. If the data you’re storing is of a sensitive nature (GDPR, HIPAA, PII, Banking, etc), you should enable encryption at rest. It does cost a very tiny bit more, but you won’t see much of a difference in performance.
Default Encryption settings – click enable if you plan on storing sensitive data.
  • Click Create Bucket to move to the next screen.
Advance to the next screen by clicking create bucket.


Now that we have a bucket, we need to grant access to the bucket. An IAM policy is like a keycard. You program the policy to grant access only to specific services. It sounds hard but it’s pretty easy if you’re just copy-pasting.

  • In a new browser window, go to the IAM console.
  • click “Policies” on the left side.
Click Policies.
  • Click Create Policy.
Click Create Policy.
  • Click JSON.
  • Delete everything in the JSON Editor.
  • Copy-Paste this JSON into the editor, replacing the word XXXXXXXXXMYBUCKETNAME with the s3 bucket name you created in step one.
    "Version": "2012-10-17",
    "Statement": [
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": [
            "Resource": "arn:aws:s3:::XXXXXXXXXXXXXXXXXXXXMYBUCKETNAME/*"

It should look like this when you’re done.

Properly updated JSON for your policy – this one is for a bucket named “s3-fm-super-sandbox”.
  • Click “Next: Tags”.
  • Click “Next: Review”.
  • Name your Policy “s3fm-s3-bucket-access”.
  • Write a description if you want.
  • Click “Create policy”.
Name your policy and click Create Policy.

This should return you to the IAM console. Good work! Two more steps to go.


Now that we have a policy, we need to assign it to a user.

  • Click Users, then click Add Users.
Click Users, then Add Users.
  • Create a name for the User. You can name it however you want, but make it functional. s3fmBucketUser is a good name if you’d rather not be creative.
  • Check the “Programmatic access” checkbox.
  • Click “Next: Permssions”.
Add a username, select Programmatic access and click next.
  • Click “Attach existing policies directly”.
  • Start typing in the name of your policy from step two in the filter field. (s3fm-s3-bucket-access)
  • Check the box next to your policy.
  • Click “Next: Tags”.
  • Click “Create user”.
Attach the policy you created in step two to the user.

AWS now has generated a username and password for to access your s3 bucket.

  • Leave your browser window open, you’ll need the credentials in step four.
  • If you accidentally close your browser window, repeat step three.


Now that you have a username and password for your S3 bucket, you’ll need to share your s3 credentials with us to allow us to upload to your s3 bucket. This is done in the API Explorer .fmp12 file.

  • Open the API Explorer with FileMaker Pro.
  • Paste your API key into the API key field. Click the logo in the top left corner. Once pasted in, the API Explorer will verify your API key’s subscription.
  • From there, just follow the prompts.

Happy uploading!
