Deprecated Server-side SDKs
All v1/v2 SDKs were retired on June 30, 2024 and will not receive further updates. To continue receiving API and SDK improvements, we recommend migrating to our latest APIs and SDKs. You can find instructions for making the switch within the README of each legacy SDK repo below.
/v1 & /v2 Legacy APIs (Deprecated) | 2022
/v1 & /v2 Legacy APIs (Deprecated) | 2012 - 2021
NOTE: /v1 & /v2 Legacy APIs (Deprecated) | 2012 - 2021 SDKs do not support all API operations
If you are currently using a legacy SDK, you may be missing some key functionality. For that reason, we recommend customers use our latest SDKs.
Alternatively, if you'd like to continue using a legacy SDK (e.g: for multi-threading/multi-store support as we work on updating this feature), you can make newer API calls that are not in the SDK by making HTTPS requests outright. For help with this, you can reference our language-specific code examples within the API reference, which lists all available operations.
