Frontend Submissions – Extension Compatibility

Frontend Submissions is compatible with many Easy Digital Downloads extensions.

Amazon S3

Frontend Submissions is fully compatible with the
Amazon S3 extension with some minor behavioral changes. Uploading works exactly the same, but Vendors may not browse the server. If they need to change files, the site admin must upload a new one. If they need to revert, they cannot browse to the original file, and they have to re-upload that original file. Read more information about Amazon S3 and Frontend Submissions here.


Frontend Submissions is fully compatible with the
Commissions extension. You can read about how that integration works in this document

Custom Deliverables

With Frontend Submissions and
Custom Deliverables your Vendors can deliver customized files to their customers. See Custom Deliverables – Frontend Submissions Integration for details.


The Dropbox File Store extension is
incompatible with Frontend Submissions.

EDD Message

EDD Message integrates perfectly with Frontend Submissions. With both active, it is possible to send unique, custom messages directly to Vendors. Additionally Vendors can send messages directly to their own customers.

Purchase Limit

There’s no direct integration between
Purchase Limit and Frontend Submissions, but if you add a text field to your Submission Form and give it a meta key of
_edd_purchase_limit, the value entered by the Vendor will be set as the limit. Please note this will only work if the Vendor is submitting a single priced product. If they are using variable prices, this method will not work. The site owner would have to edit the submitted product(s) manually.

Recurring Payments

Recurring Payments and Frontend Submissions are not fully integrated. Vendors will not be able to set recurring payment details in the submission form. However, recurring payment functionality can be enabled for vendor-uploaded products through the Edit Download screen by the site owner once submitted.

Simple Shipping

Simple Shipping and Frontend Submissions are both active, a “Shipping” field will become available in the “Add Extension Created Fields” section of the Submission Form. When this field is added to the Submission Form, Vendors will be able to define their own international and domestic shipping rates for each product. Additionally, if a Country field is added to the Vendor profile form with the meta key “vendor_country”, shipping calculations at checkout will be based on that value instead of the one saved in the Simple Shipping settings. See detailed instructions here.


EDD Slack includes an integration with Frontend Submissions. With EDD Slack it is possible to receive notifications within your Slack channels when Vendors register, submit products, and edit products as well as when customers contact Vendors. Additionally, EDD Slack can include interactive buttons within notifications for Vendor applications, submissions, and product edits so you can approve or reject the request right from Slack without having to login to your WordPress dashboard.

Software Licensing

While completely compatible, watermarks are configured by the site admin. Vendors cannot control the watermark settings.

PDF Stamper is partially supported. The stamps applied to PDF files must be configured by site admins (vendors have no control over PDF Stamper), but once configured, any PDF file that is sold by a Vendor will get watermarked.
