There is one submit route in the Borrow API and no separate submit-hash route. Send exactly one body field:

Body	Use when	Result
`{ "signedPayload": "..." }`	yield.xyz broadcasts the signed transaction. Up to 1 MB.	`status` `BROADCASTED` with `transactionHash` and `link`
`{ "transactionHash": "0x..." }`	You already broadcast it. Must be `0x` plus 64 hex characters.	`status` `BROADCASTED`; the hash is recorded, not checked on chain at submit time

Sending both, or neither, returns 400. These are not the Earn field names signedTransaction and hash. A transaction can be submitted once, and only from CREATED. Any later call returns 400 Transaction <id> is not ready for submission. Status: <status>, including after a failed broadcast. Submit an action’s transactions in the order returned, then poll Get an action for CONFIRMED and the action’s final status. The success response is always BROADCASTED; it does not mean confirmed.

Status	Cause
400	Both or neither body field; invalid hash format; transaction is not `CREATED`
404	Unknown `transactionId`, or the transaction belongs to another project
503	Broadcast of `signedPayload` failed; the transaction is marked `FAILED`
