Description

Connects to the external custodian provider (e.g., Fireblocks) using provided API credentials to retrieve wallet data and validate the connection before creating a custodian. This helps verify credentials and preview which wallets will be imported.

​
Input

Expects a JSON body containing:
  • tenantId (long, required) — Identifier of the tenant.
  • accountName (string, required) — Display name for the custodian account.
  • provider (string, required) — Name of the custody provider (e.g., “Fireblocks”).
  • apiKey (string, required) — API key for accessing the provider’s API.
  • secretApiKey (string, required) — Secret key for API authentication.

​
Output

Returns a response object containing:
  • walletsCount (int) — Number of wallets found in the custodian account.
  • validationStatus (bool) — Whether API credentials are valid.
  • message (string) — Additional information about the validation.

​
Examples

  "data": {
    "walletsCount": 15,
    "validationStatus": true,
    "message": "Successfully connected to Fireblocks and retrieved wallet data"
  },
  "isSuccess": true
}

​
Errors

  • 400 Bad Request: Invalid credentials or missing required fields.
  • 401 Unauthorized: Authentication required but not provided.
  • 403 Forbidden: Caller does not have permission to access custodian data.
  • 500 Internal Server Error: Connection to custodian provider failed or unexpected error occurred.
