Welcome to the Yoli API Docs

Yoli Logo

Yoli takes care of the bank accounts, contracts and documents of the user - daily, forward-thinking and action-oriented.

The user connects his bank accounts with Yoli, whereby Yoli uses a payment stream analysis to automatically detect the user's contracts and subscriptions. In addition, various Smart Actions such as switching or canceling contracts are offered by best-case partners.

Furthermore the user has the possibility to connect the online portals of his contract partners to automatically import his contract documents into Yoli, which considerably simplifies the contract management of the customer. Yoli detects life-changing moments in every phase of life, enabling customer-oriented product placement at the right time via the smart feed.

What to Expect ⭐️

The Yoli API provides access to Yoli's complete feature set. This includes the handling of bank accounts, contracts and smart alerts. Individual bank accounts can be hidden or entire accesses can be removed to adapt the considered information to the specific needs of each Yoli API user. When connecting bank accounts, contracts are automatically detected and various meta information about the users financial situation can be derived from them. Contracts can be customized and extended by the user of the Yoli API. Our providers Verivox and ComAds can be leveraged to compare contract offers and switch contracts.

We Use GraphQL 🎉

GraphQL Logo

GraphQL is a query language for APIs and a runtime for fulfilling those queries with our existing data. GraphQL provides a complete and understandable description of the data in our API, giving the Yoli API clients the power to ask for exactly what they need and nothing more.

GraphQL is convenient and very easy to learn. The query language is similar to JSON and basicly describes what data is expected in the response. The response itself is common JSON.

Ask for What You Need

Send a GraphQL query to the Yoli API and get exactly what you need, nothing more and nothing less. Our GraphQL queries always return predictable results. Clients using our GraphQL API are fast and stable because they control the data they get, not the server.

Example query that you send to the Yoli API.

  searchBanks(search: "fino Bank") {

Response from the Yoli API containing exactly what you need.

  "data": {
    "bankSearch": [
        "shortName": "fino Bank",
        "city": "Kassel"

Why Not REST?

The Yoli API is a powerful toolset that is used by many applications in various fields. The Yoli API is used for example in our Yoli iOS, Android and Web Apps - additionally as white label versions. In addition, several other applications use the Yoli API to integrate certain Yoli functionality into existing applications.

In order to optimally map these different application scenarios, we chose GraphQL as dynamic interface to the entire Yoli technology. With GraqhQL, the client has the power to decide what information is needed in each situation. In addition, cross-thinking requirements can be met.

In contrast, we would only offer predefined interfaces with REST, which would always have to be extended for different use cases. This is not necessary with GraphQL. Therefore, as a user of the Yoli API, you decide when to integrate which functionality.
