Explanation of the key concepts we use when we talk about Sharetribe Flex. The concepts are used in the API and throughout the documentation.

Application concepts

Description of the applications and services that are included in the Flex offering.


The user interface admins use to build their marketplace platform. Console is also where the day-to-day management, such as overseeing users’ activity, monitoring listings and reviews, and managing notifications, takes place.

Flex Templates for Web (FTW)

A template of a Flex marketplace user interface. Sharetribe customers can customize FTW for their own marketplace, or build their own UI from scratch. Flex Template for Web is built with Node.js + React/Redux.

Currently we have three different template options:

  • FTW-daily "Saunatime" - a rental marketplace with day-based bookings
  • FTW-hourly "Yogatime" - a service marketplace with time-based bookings
  • FTW-product "Sneakertime" - a product marketplace with stock management

Information about using Flex Template for Web can be found in the Getting started with FTW tutorial.

Flex CLI

Flex CLI (Command-line interface) is a tool for changing your marketplace's advanced configurations such as transaction processes and email templates.

See the Getting started with Flex CLI tutorial for more information.

Marketplace API

The application programming interface (API) that provides the crucial features marketplaces need. For example, the Marketplace API allows creating and searching content (like user profiles and listings), managing user accounts, and processing transactions.

Sharetribe customers can create their own web-based and mobile UIs on top of the Marketplace API.

Information about working with the Marketplace API can be found in the API reference documentation.

Integration API

The application programming interface (API) that provides full access to marketplace's data. It can be used to build applications that integrate different own or 3rd party systems with the Flex marketplace.


An external application that communicates with the marketplace (typically via the Integration API). This can mean reacting to marketplace events, pulling data from the marketplace, or triggering activity on the marketplace. For example, “automatically update a Mailchimp email list when a new user joins the marketplace”.

Sharetribe Flex

An umbrella name for the entire Sharetribe Flex offering that today consists of the Marketplace API, Console, Flex Template for Web, and the documentation.

Sharetribe SDK for JavaScript

A JavaScript library that makes it easy to correctly interact with the Marketplace API.

Information about using the JS SDK library can be found in the JS SDK documentation.

Sharetribe Integration SDK for JavaScript

A JavaScript library that makes it easy to correctly interact with the Integration API.

Information about using the JS SDK library can be found in the JS SDK documentation.


A way to send automatic and/or manual messages to external applications (like email or SMS) to users when something important happens on the marketplace. In practice, this is done with JSON messages that are delivered via HTTPS to the endpoints the admin chooses.

Flex does not offer webhooks. Instead, Flex exposes events that allow you to achieve many of the use cases where webhooks would be used.

Marketplace concepts

The key concepts in the Sharetribe Flex marketplace domain.


The technical identification information of a user. Users can register to a marketplace by creating an account.


A marketplace operator account allows access to Console, where the day-to-day management of the marketplace takes place. The admin is not a marketplace user, so this account can't be used to log in to the actual marketplace.

Availability plan & availability exception

An availability plan is a recurring plan for the dates and times when a listing is available. For example, a provider can mark their listing to be available by default on weekdays (Mon–Fri) from 8am to 8pm, and unavailable during night time and on weekends.

An availability exception is a deviation from the availability plan. For example, the provider can make an exception and also mark selected Fridays unavailable, or make certain weekends available for overnight bookings.

Banned user

Banning a user means removing the user and all of the user’s listings from a marketplace due to inappropriate behaviour. The email with which a banned user registered to the marketplace can't be used to create new accounts. The user data is only visible when it’s linked to (only ID + banned status are shown).


A reservation of a listing for a specific time.

Closed listing

A published listing can be closed by its author or the marketplace admin. Closed listings are not returned in search results or public listing queries. This doesn't mean the listings are deleted: they can still be accessed as own listings or with a direct URL.

The motivation for closing a listing is not to delete it, but to (temporarily) stop advertising it. A closed listing can be opened, which makes it published again.


The amount of money that a marketplace charges from payments going through it. Commissions can be charged from providers, customers, or both.

Customer (buyer)

A user who registers to a marketplace to make purchases. In general, any registered marketplace user can make purchases on the platform. So, all users are always (potential) customers – including the providers.

We use the term “customer” instead of “buyer” because marketplace platforms can be used for much more than buying and selling products.

Delayed payout

A payment that a customer has made but that hasn't been transferred to the provider yet.

Deleted listing

Deleted listings are completely removed. They are only visible if they are linked to from a transaction. In that case, only the listing ID and the deleted status are shown, the listing’s information is not visible.

Deleted user

Deleting a user means completely removing all of the user's personal data. This includes all of the public-facing data like profile and listings as well as the user account information.

Draft listing

A listing that is created but not yet published. A draft listing is visible to the author and to the marketplace admin but not discoverable by any public API endpoints.

Extended data

Additional data that can be attached to marketplace objects. Extended data is available out of the box and can be written and read via the Marketplace API without any prior configuration. There are different types of extended data available (e.g., public, protected, or private).

In practice, extended data allows a marketplace operator to decide, for example, how much and what kind of information they want their users to fill in to their profiles. Extended data can also be attached to listings and transactions.

Extended data search schema

It's possible to define search schemas for some extended data types. Defining a schema allows that data type to be indexed so that search queries can be made for that data.


A description of a product or a service that a provider is offering on the marketplace. The provider of a listing is called the author of that listing.

Listing pending approval

Marketplaces can require all listings to be approved before they are published on the marketplace. A listing that is pending approval is visible only to its author and the marketplace admin, but not discoverable by any public API endpoints.


A platform that connects providers and customers. The marketplace is the primary scope for all data, such as users, listings, orders, and so on.


Free form text attached to a transaction. Messages are exchanged between a customer and a provider when they engage in a transaction.


A message that a user gets when something important happens on the marketplace (e.g., the user has received a message or a payment on the platform). Notifications are delivered via email.


The amount of money paid by the customer.


The transfer of money from one party to another (customer to provider, provider to marketplace admin, etc.)


The amount of money that is moved to the provider.

Typically, marketplaces take a commission from each payment. This means that often, the payin from a customer is a larger sum than the payout to a provider.


The public-facing information of a user. Profiles can include things like avatar, bio, link to a webpage, reviews, and contact address.

Provider (seller)

A user who sells or rents their products or services on a marketplace. Providers can post listings to the marketplace.

We use the term “provider” instead of “seller” because marketplace platforms can be used for much more than buying and selling products.

Published listing

A listing that all registered users on the marketplace can see in search results or public listing queries.


After a customer and a provider have engaged in a transaction, they are asked to describe how the experience with the other party was. This description is called a review. A review includes a free text description and a numeric rating between 0-5.


Determines what a user is able to do on a marketplace. For example, “Admin” and “Provider” are roles on a marketplace.


The quantity of available units for a certain listing.

Stock adjustment

A record of change in the quantity of stock for a given listing. For example, a positive stock adjustment represents an increase in stock quantity, while a negative stock adjustment represents a decrease.

Stock reservation

A reservation of some quantity of stock. The reservation is typically created as part of a transaction.

Time slot

A day or a time range when a listing is available for booking (taking into account the listing's availability plan, availability exceptions, and existing bookings).


The process of providing the product or service that is listed on a marketplace. Transactions have a predefined set of states and transitions between states, which are defined in the transaction process.

Transaction process

The process where a customer and a provider exchange value.

The transaction process begins with the first interaction the customer and provider have with each other. It defines the states and transitions between the states that a transaction can take. It also defines the actions that happen as part of the transitions. Examples of actions are creating a payment, reserving a time slot, or publishing reviews.


Anyone who registers to a marketplace is referred to as a user.
