> ### Release of Tangany API-Suite 2.0

> > ##### Official release date: **24/04/2023** > > > At the beginning of March, we [announced the official beta phase of our new API Suite 2.0](https://tangany.com/blog/we-start-into-a-new-era-tangany-api-suite-2-0). Thanks to the valuable feedback of many partners and contributors, we have implemented optimizations and made some final touches. > > **From the 24/04/2023 the use of Tangany API Suite 2.0 is available for production environments.**
> New partners who have already used the Partner Portal and API version 2 via our sandbox can use all our services productively by contacting our [application support](https://support.tangany.com/support/tickets/new).
> The major change for all Tangany APIs is the switch from subscription-based authentication to OAuth2 authentication. For more information especially about the changes to the individual APIs take a look at the [origin announcement](https://tangany.com/blog/we-start-into-a-new-era-tangany-api-suite-2-0) and our official API documentation at [docs.tangany.com](https://docs.tangany.com).

> > > ### Migrate from API version 1 to version 2 > A Migration will be necessary for all long-term partners currently working productively with Tangany API version 1.x.x (v1). Our aim here is to work with each partner to prepare a secure and stable path for migrating partner applications to the version 2 (v2) world without downtime. We have developed a migration concept enabling each partner to make a guided transition.

> **Migration steps:** > 1. Talk to your Key Account Manager or Application Support Engineer or [contact Tangany support](https://support.tangany.com/support/tickets/new) to get your account for the Tangany Partner Portal. > 2. Create a sandbox workspace, your API subscriptions, and API Accesses. > 3. Update your application code to be compatible with v2. > 4. Plan your release and inform us of your estimated release date. We will create a new v2 workspace and subscriptions for you and start synchronizing your data from v1. Once we have prepared this for you, you can release and use v2 at any time. > 5. Create your productive API Access, use it in your application, and release your application. > > **Important:** Note that you **should not do any write operations to v1** after you've started using v2. Otherwise, you may have conflicting changes with v2. >

> *Do you want to migrate immediately and go live with v2 tomorrow?*
> Please give us some time as we want to ensure that every partner is taken care of professionally and qualitatively to avoid any issues. Therefore, we have established a waiting list for partners who contact us during step 1, and your dedicated contact person will keep you informed throughout the process. >

> ### Deprecation of version 1

> ##### Official shutdown date: **30/11/2023** > > With the go-live of Tangany API-Suite 2.0, we also announce the deprecation of Custody API v1, Settlement API v1, and Customers API v1.
We will still support those and keep them running until 30/11/2023.

> From 01/12/2023 Custody API v1, Settlement API v1, and Customers API v1 will not be accessible anymore.
> Therefore, we ask all partners still using v1 to plan and implement the changeover to v2 as early as possible. >

## Introduction Welcome to the API documentations of the Tangany API Suite! The Tangany API Suite provides sophisticated regulatory crypto-banking solutions for businesses built atop an uncomplicated Web API. To get started, follow this introduction, begin browsing through our different API Products or check out our Postman collection, including all Tangany APIs. ## API Products ### Tangany Custody API (Wallet as a Service)

Leverage Wallet as a Service to bring digital assets to your customers. This API is our powerful solution to integrate blockchain wallets into any system. It's scalable, reliable, and easy to use. For more details see our [API Documentation](https://tangany.stoplight.io/docs/tangany-custody-api) or start coding with our [quickstart](https://medium.com/tangany/send-ethereum-transactions-using-tangany-waas-2252e94cabe5). ### Tangany Customers API

The Tangany Customers API provides a central, API-based administration of your customers for using other Tangany APIs. It also includes regulatory features like handling KYC data. Checkout the latest [API Documentation](https://tangany.stoplight.io/docs/tangany-customers-api) to include customers data in your solution. ### Tangany Settlement API

The new kid in town is our Tangany Settlement API. This API can be used for blockchain virtualization, for example, to work with omnibus wallets. After you have managed your customer's accounts, you can virtualize transactions to settle those later aggregated to any blockchain. For a more detailed view into that API see our [API Documentation](https://tangany.stoplight.io/docs/tangany-settlement-api). ## Postman Collection To get started with the Tangany API Suite, we offer a public [Postman](https://www.postman.com/) workspace containing API collections from all our API solutions.
