Troubleshooting in Yandex SpeechKit

If something went wrong while sending API requests and you need help, contact technical support.

The support team will solve your issue faster if you use advanced HTTP request and response headers.

Request headersRequest headers

When sending HTTP requests, use the following headers:

• x-client-request-id is a unique request ID. We recommend using a UUID. Send this ID to the technical support team to help us find a specific request in the system and assist you.

  You can generate a UUID either online or through the library for the programming language you use.

• x-data-logging-enabled: Flag that allows saving the data provided by the user in the request.

  By default, we do not save any audio or text you provide. If you provide the true value in this header, your data will be saved. This, along with the request ID, will help the technical support team to solve your problem.

ExamplesExamples

For example, you can use these headers to let us know afterwards that your audio was poorly detected and help us refine our speech recognition model.

Here is a sample request using cURL:

export FOLDER_ID=<folder_ID>
export IAM_TOKEN=<IAM_token>

curl \
  --verbose \
  --request POST \
  --header "x-client-request-id: fa18fa9b-176d-4ae0-92b8-bd78********" \
  --header "x-data-logging-enabled: true" \
  --header "authorization: Bearer ${IAM_TOKEN}" \
  --data-binary "@speech.ogg" \
  "https://stt.api.cloud.yandex.net/speech/v2/stt:recognize?folderId=${FOLDER_ID}"

Where:

• FOLDER_ID: ID of the folder for which your account has the editor role or higher.
• IAM_TOKEN: IAM token used for authentication.

Response headersResponse headers

Each server response contains headers that provide even more information about the request execution:

• x-request-id: Unique response ID
• x-server-trace-id: Unique request execution log ID

To retrieve the x-request-id and x-server-trace-id values, your application must log server response headers.

You can find an implementation example for access to gRPC headers in the grpc-go library documentation.
