Supported OpenAPI semantics

OpenAPI semantics

Resource schemas (const)

Speakeasy support

✅ Full support

Comments & limitations

When an attribute in an OpenAPI document is specified as

, it is removed from a Terraform schema and automatically included in requests or assumed in responses.

Resource schemas (default)

Speakeasy support

✅ Full support

Comments & limitations

When an attribute specifies a default value, this value will be used whenever that attribute is not explicitly set, ensuring consistency and reliability.

Server configuration

Speakeasy support

✅ Full support

Comments & limitations

The provider includes a

variable, allowing it to be used with any API server. By default, this variable is set to the first entry in the

field of the OpenAPI document.

Global authentication

Speakeasy support

✅ Full support

Comments & limitations

All authentication mechanisms that rely on static authorization are supported, with their values automatically configurable in the provider settings.

Query parameter serialization

Speakeasy support

✅ Full support

Comments & limitations

All query parameter attributes will be available as resource or data source attributes in a Terraform-native format. Might require remapping through
