Why is Square retiring Connect v1?
Permalink Get a link to this section

The Connect v1 APIs were introduced in 2014. Since then, Square has collected developer feedback and learned more about building robust APIs. The result is an improved Square API data model (previously known as Connect v2) that supports versioning, lays the foundation for a unified development platform, and establishes scalable patterns for future functionality.

Retiring the Connect v1 APIs will allow Square to expand interoperability with first- and third-party products, implement consistent versioning policies, and support regular iteration on functionality in response to developer feedback.

What will happen?
Permalink Get a link to this section

As gaps between the Square API model and Connect v1 are filled, the corresponding Connect v1 APIs will be deprecated. Square strongly recommends against using Connect v1 APIs for new applications. Deprecated endpoints are clearly flagged in the Technical Reference and Square will provide migration guides for affected developers.

Important

Some Connect v1 functionality will not be implemented in the Square API due to low usage. Where possible, the applicable migration guide provides an alternative approach.

When will my code break?

Connect v1 APIs are deprecating as their replacements become publicly available. Once a given API is deprecated, existing users will have 12 months to update their code before the functionality is retired and permanently disabled. For more information about how Square handles API deprecation and retirement, see the Square API Lifecycle overview.

What happens if I call an API after the retired date?

Your code will break.

Retired functionality cannot be used, regardless of the Square-Version provided during the API call. Square SDKs released on or after the retirement date do not include retired features and REST calls that attempt to use retired functionality return errors.
