An API key by itself authenticates nothing. Each call requires four headers together: `X-Api-Key` (your key), `X-Signature` (HMAC-SHA256 of `apiKey + timestamp` — or `apiKey + timestamp + userId` when `X-User-Id` is required — keyed with your API secret), `X-Timestamp` (unix seconds), and `X-Request-Id` (any unique string per request). The signature must be computed by a client script; there is no way to derive it by hand. Use the HMAC Generator flow to compute valid values for manual testing. ## Common Authentication Errors - **Invalid Client ID**: {"error_code":6092,"message":"X-Client-Id invalid","success":false} - **Invalid Secret**: {"error_code":6090,"message":"invalid secret","success":false} - **Timestamp (Older than 10 secs)**: {"errors":{"error_code":6093,"text":"timestamp expired"},"success":false} servers: - url: https://api.saber.money security: [] paths: /api/v2/user/kyc/upload_document: post: tags: - KYC and EDD Operations summary: Send User KYC Documents description: > Share User KYC PII supporting documents (PDF, image, or Aadhar XML) Request must be sent as `multipart/form-data` with the `file` field containing the document. operationId: send-user-kyc-documents-v2 parameters: - name: X-Api-Key in: header required: true description: Your API key (configured in credentials) schema: type: string - name: X-Signature in: header required: true description: >- HMAC-SHA256 signature (auto-generated) To test manually: HMAC-SHA256 of `apiKey + timestamp` (or `apiKey + timestamp + userId` when X-User-Id is required), keyed with your API secret.
