Hi [First name]!

Digital files are important for many marketplaces: providers deliver their work as files, customers sign contracts, and you might ask new users for verification documents at signup. Sharetribe’s no-code version already lets users attach files to messages and add them to digital download listings.

Now, two new API features, private user files and updatable transaction files, open up even more use cases. Adding them to your marketplace requires custom code, but even if you’re not a developer, you can add them with AI-assisted coding.

Here are just a few things you can build:

Collecting a verification document like proof of insurance or a certificate when a user signs up
Letting providers save files they send often, like a price list, so they don’t need to upload them again each time
Letting providers replace files delivered by mistake with correct ones
Asking a customer to upload a signed PDF contract before moving a transaction forward
Asking a provider for proof of delivery before payout, like a receipt or photos

Read on to learn more, and try the AI-assisted coding tutorials linked at the end of this email.

Private user files

Private user files are stored on a user’s account, and only the user and you, the operator, can access them. You can use private files to collect verification documents at sign-up or let providers save files they reuse across transactions.

The signup for for a freelance marketplace built on Sharetribe. In addition to the default fields, email, name, and password, the form has a button to upload resume. Only freelancer users need to upload it (customers don't).

You can view and download private files in user management in Console.

A user's card in the freelance marketplace Console. The operator can see the resume file that a freelancer called Dave uploaded.

Updating transaction files

The files shared during a transaction, for example in the digital download transaction process, are called protected files. A new transaction process action lets users update a transaction’s protected files. You can also update files through the Integration API.

For example, you can let providers replace wrong files, or ask customers to upload a signed agreement after a booking is accepted.

An example Sharetribe marketplace for knitting patterns called Yarntribe has a feature where sellers can replace the pattern file in a transaction. A seller is switching the wrong file, a resume, to the correct one, a cardigan pattern.

Start using these API features with AI-assisted coding

While these features require custom code, you don’t need to be a developer to make use of them. AI coding tools like Claude Code can write the code for you from a plain-language description. This is called AI-assisted coding, or vibecoding, and we have a helpful tutorial on how to get started with it in our Help Center.

With Sharetribe’s new pricing, you no longer need to upgrade your plan to make custom code changes, so it’s a great time to give AI-assisted coding a try.

Here are tutorials of some features mentioned above that you can add to your marketplace. Use the prompts in the articles as is, or modify them to your exact needs:

Collect verification documents at signup: New users upload a file when they sign up, like a resume or certificate.
Let sellers replace digital download files: Sellers can swap the files of a digital download order, and buyers see the new files on their order right away.
Saved files in transactions messages: Users can save a file they've sent in a message, such as a price list, to attach it to later conversations without uploading it again.

Or build something else! Ask a provider for proof of delivery before payout. Ask renters to upload photos of an item’s condition at pickup and return. There are plenty of opportunities to add unique functionality with AI. You can build the exact user flows your marketplace needs.

Just remember: AI output is never exactly the same, so test your modifications carefully before releasing them to real users.

Do you have more file-related needs? Let us know!

These new API features are the last in a series of launches to add support for digital files in Sharetribe. Together with our no-code file features, they cover many of the workflows founders have requested from us.

In case you have another file feature in mind, we’d love to hear about it! Let us know by replying to this email.

New in Sharetribe 🎉 Private files and updatable transaction files

Two new file features are now available in Sharetribe’s APIs. Let users upload private files only they and the operator can see. Allow users to update transaction files. You can add the new file features with AI-assisted coding, even without previous development experience.
