The Terraform Plugin SDK (SDKv2) is the legacy SDK for building Terraform providers. Its documentation covers provider schema definitions, resource lifecycle, acceptance testing, and migration guidance to the Plugin Framework. It is versioned and stored in content/terraform-plugin-sdk/.
The content API uses the terraform product slug. The navDataPath for this directory is plugin-sdkv2, and content is served under the /plugin/sdkv2/ URL base path.
For new provider development, HashiCorp recommends using the Terraform Plugin Framework instead of the Plugin SDK. The Plugin SDK remains supported for existing providers. Content directory
