Response Pre-Translation Normalizer Capability

The response pre-translation normalizer capability rewrites upstream responses before the host's native response translation. It is suitable for fixing provider-native payloads before they are handled by the host or by a plugin response translator.

  "capabilities": {
    "response_before_translator": true

Methods

Method	Purpose
response.normalize_before	Returns the normalized response body before response translation.

Request And Response

The request uses ResponseTransformRequest, and the response uses PayloadResponse:

{
  "Body": "base64-normalized-provider-response"
}

Difference From Post-Translation Normalization

• response_before_translator handles provider-native responses.
• The response post-translation normalizer capability handles responses after they have already been translated into the client protocol.

Development Notes

• This is suitable for fixing missing upstream fields or non-standard provider responses.
• Do not output the client protocol format unless the current stage's ToFormat is already that format.
• A plugin can declare both capabilities when it needs to support both pre-translation and post-translation normalization.
