Headers
A JWT signed using your Wallet Secret, encoded in base64. Refer to the Generate Wallet Token section of our Authentication docs for more details on how to generate your Wallet Token.
An optional string request header for making requests safely retryable. When included, duplicate requests with the same key will return identical responses. Refer to our Idempotency docs for more information on using idempotency keys.
Required string length:
1 - 128A JWT signed using your Wallet Secret, encoded in base64. Refer to the Generate Wallet Token section of our Authentication docs for more details on how to generate your Wallet Token.
