PutParameter

Source: src/AWS/SSM/PutParameter.ts

Runtime binding for ssm:PutParameter.

Bind this operation to a Parameter inside a function runtime to get a callable that writes a new version of the bound parameter — e.g. flipping a feature flag or rotating a stored secret at runtime. For SecureString parameters the binding also grants kms:Encrypt and kms:GenerateDataKey on the parameter’s encryption key.

Pass Overwrite: true to update the existing parameter (the parameter already exists — it is managed by the Parameter resource). Note that a runtime write drifts the value from the deployed desired state; the next deploy converges it back.

Writing a Parameter

const putFlag = yield* SSM.PutParameter(flag);

const result = yield* putFlag({ Value: "on", Overwrite: true });
yield* Effect.log(`flag now at version ${result.Version}`);
