API Guide

Explore the available LeanIX APIs and how to best utilize them to meet your needs.

Overview

There are many options for creating, reading, updating, deleting data from and to LeanIX. Many of these options overlap which can be utilized in multiple use cases. This guide might suggest that the Integration API is the best choice for a particular use case. However, it does not suggest that you cannot achieve similar results using GraphQL for example.

Prior to taking a look at available technical tools, it is useful to have basic knowledge of the LeanIX Data Model. For an introduction to the Data Model please see Data Model.

To see the full list of APIs and details on how to use them please see the Available API section.

We have a built-in editor for many of these tools. To access them go to your Administration area click the user icon on the top right corner and select Administration:

To access GraphiQL, Webhooks, and the Integration API built-in editors see the below:

Integration API: Import/Export Data

About the API

The Integration API is extremely flexible and powerful. One of the main reasons is at the heart it is driven by a generic LeanIX Data Interchange Format (LDIF). This imparts many benefits, which include but are not limited to:

Complexity is minimized as developers no longer have to understand the LeanIX data model

No longer have to map logic inside a code

The Integration API can be utilized to build an integration between LeanIX and another vendor system. One major advantage is that the CRUD operations for any inbound (other vendor system to LeanIX ) is managed within LeanIX, which removes a great deal of complexity.

The ability to define variables, exceptions, use JUEL expressions to extract or import only particular values that meet what you define, is powerful.

Additional benefits

In addition, there are other benefits imparted by the Integration API that are not specifically related to the LDIF structure:

Configuration for LeanIX is contained in every connector

Integration now possible even if the external system does not allow direct access

No need for a direct REST connection

Flexible error handling, no failure due to a single or even multiple data issues. Data that does not meet the requirements, is simply ignored

Cross-cutting concerns are part of the API and in each connector

It can also be used to import/export from your workspace. This can be useful in cases where the built in import/export functionality doesn't have the capability that is required. An example of such a case are attributes which exist on relations. At this time it is not possible to mass update attributes on relations using the UI.

The flexibility of the Integration API shines in more complex cases such as: when the data from the source system is not in a "clean" state. In this case the Integration API would be a good option due to its error handling capabilities. It is flexible and any errors can be ignored (this is not the case with built-in Inventory import/export or GraphQL). In addition, the Integration API supports the use of JUEL/RegEx which imparts the ability to transform the source data, for example you can utilize .sum() to add up costs and then file that into a cost attribute in LeanIX. Please see the Integration API documentation for detailed information.

Use Cases

  • Build an integration with an external system for example ITSM Integration.
  • Make one-off updates to your workspace which you would normally use in the import/export functionality via UI.
  • Merge two or more separate physical workspaces. This might be necessary in case of an acquisition or merger.

GraphQL: insights from data

GraphQL allows you to query the data on your fact sheets as well as mutate (e.g update, delete) the data. In addition, GraphQL is utilized to create custom reports, specifically to pull data from the workspace and present it using charts and other graphics.

Use the built-in GraphiQL Tool available within your LeanIX Administration area when you need answers to your fact sheet data. In addition, the GraphiQL Tool allows you to interactively develop and test queries and mutations. Which later can be utilized in scripts to automate work or custom reports.

Once in the Administration area, from the "Developers" tab select "Tools" then select GraphiQL.

GraphQL Basics

In order to get a fundamental understanding of GraphQL. You need to understand two main ideas, queries and mutations.

A query allows you to formulate precisely what arguments to return and what filters to apply.

A mutation allows you to apply patches (updates) or delete objects. Again, you can combine patches or define precisely what arguments to return.

Benefits of GraphQL

Developers can summarize multiple API calls in one. This allows them to focus on the business logic instead of combining call results and handling different transactions.

In particular for large reports or analytics, GraphQL increases performance dramatically. Now, you can transfer exactly the attributes you require via the network, with no extra latency. Furthermore, GraphQL aligns perfectly with an underlying Graph Database to answer queries that span multiple relations, e.g. Evaluating Technology Risk Transitively.

The GraphQL schema is strongly typed. This is an asset as the strong typing defines that the API is largely self documented. You can see what the immediate response to the query will be.

Since everything in GraphQL is schema driven, extending it won't be a problem if a new field is added. This won't affect the existing fields and also GraphQL introduces @deprecated annotation to deprecate fields. This eliminates the need for versioning the API.

GraphQL Capabilities

Export of Applications with specific attributes

Export of specific relationships between two fact sheet types

Export of external ID's for all Applications

Update specific attributes on specific fact sheets

Create relations

The best cases for utilizing the GraphiQL Tool:

  • Focus on queries, and or mutations that are one-off in nature or for which you do not need to regularly (e.g monthly, weekly) get up-to-date information.

  • Where you need to pull relatively simple information. While complex queries are very much possible to an extent, there are other alternatives such as the Integration API which you might find easier and flexible choice.

  • GraphQL features heavily in custom reports because it is used to pull information from the workspace which is presented using charts and other graphics.

Endpoints and scripts

The GraphQL API endpoint can be utilized to create scripts and build a REST API. It might be best to review the functionality available within the Integration API, because it is expressly created to resolve or minimize several challenges developers face when building an integration.

Please see the GraphQL in 10 minutes documentation for more detailed information on GraphQL and GraphQL Advanced.

The public LeanIX GitHub contains many scripts that utilize GraphQL. Some of the scripts are listed below:

Webhooks: Event Driven Information

Webhooks: Event Driven Information

Webhooks allows an application in LeanIX to supply other applications with real-time information. Which allows webhooks to furnish data to other applications as it occurs. In contrast to traditional API's where to get up-to-date information the app would need to send a request. This makes webhooks an efficient choice for provider and consumer.

What are events? Events in this context are actions that end users take within an application. Some examples are entering a response within an attribute such as the Description field, creating a new fact sheet, or even logging into LeanIX. When you need an event driven integration, webhooks is the answer. One such use case is when you need to trigger notifications to be sent based on when a fact sheet (or an attribute/field on the fact sheet(s)) is updated, created, or deleted**.

Many systems offer a built-in user interface to allow end users to easily create simple webhooks. LeanIX offers user interface within the Administration area of your workspace in addition to an API endpoint.

To get an introduction to webhooks please see the "Getting Started Webhooks" documentation.

Use Cases

  • Send Alerts to Slack and Teams.

  • Build a Slack Bot using webhooks.

  • The technical suitability is updated on a fact sheet, this event can trigger a tag to be automatically added to the fact sheet. Please see the Azure Function Tutorial: TIME tutorial for an example of this implemented with Webhooks and Azure function.

  • Utilizing the responses from a LeanIX survey to calculate a particular score and the score can be automatically set to be associated to a fact sheet.

Metrics: Data Over Time

With Metrics you can store time series data in LeanIX and create interactive charts to display the data. In addition, the data can be linked to Fact Sheets presented on Dashboard or be displayed within the Reports area.

Metrics consist of several objects including measurements. Measurements contain data-points stored over time, which are related to the same topic. Each data-point is stored for a specific moment and has one or more values for that instance of time.

Metrics are very specific to cases when there are data points that are time based. One such example is when expenses or other costs need to be understood on the basis of time.

For more information please see Getting Started with Metrics.

*Available APIs

LeanIX is built with a Microservices architecture, with different services and API endpoints. Below is a list of all public APIs. For each entry, the main resources, endpoint URL and links to Swagger API References are listed.

Your Endpoint Base URL (often referred to with the variable 'base_url' in our public scripts and tutorial examples) will vary depending the domain of your workspace. The simplest way to determine your endpoint base URL is to pull it directly from the URL displayed in your browser when navigating your workspace "https://...leanix.net".

For example:

If my main dashboard URL were https://MyCompany.leanix.net/MyCompanyWorkspace/dashboard/184710fa-4272-4163-ba99-ddfcb46eaf4a, my endpoint URL would be https://MyCompany.leanix.net

Integration API: Import/Export Data and Build Integrations

The Integration API provides the ability to import/export data using a generic LeanIX Data Interchange Format (LDIF). LDIF is a JSON format with a very simple structure described in the following sections. In addition, building integrations between LeanIX and other vendor systems is simplified using the Integration API. One of the reason is because all mapping and processing of the incoming and outgoing data is done using "Data Processors" that are configured behind the API. For detailed information including use cases please see Integration API.
