Intra Account Transfer
Transfers funds within the same account.
When source_exchange_shard and destination_exchange_shard are the same, Kalshi treats the request as a subaccount transfer. The returned transfer ID appears in the subaccount transfer history.
Cross-exchange-index subaccount transfers run in up to three non-atomic steps. If a later step fails, completed steps are not undone, so funds may remain in the primary account on the source or destination exchange index.

Your API key ID
Base64 signature of the pre-sign text (timestamp + method + path) made with the API key's algorithm - RSA-PSS with SHA-256 for RSA keys, Ed25519 for Ed25519 keys
Request timestamp in milliseconds
Body
application/json
The source exchange instance
Available options:
event_contract, margined The destination exchange instance
Available options:
event_contract, margined The amount to transfer in centicents
Client ID for duplicate prevention. Reuse only to retry the same request: if a transfer from the same source exchange instance and shard was already accepted with this ID, the request returns 409 and creates no new transfer. The returned transfer_id is always generated by Kalshi. Only supported for primary accounts. Transfers involving numbered subaccounts reject this field. If omitted, each request creates a new transfer.
Source exchange shard index (default 0)
Required range:
0 <= x <= 100Destination exchange shard index (default 0)
Required range:
0 <= x <= 100Source subaccount number (default 0 for the primary account). Only supported for event contract to event contract transfers.
Destination subaccount number (default 0 for the primary account). Only supported for event contract to event contract transfers.
Response
Transfer request accepted. The transfer is processed asynchronously.
The ID of the transfer that was created
