This /one-step API can cover two situations:

Pre-transaction Travel Rule: if your VASP as Originator VASP, initiating a Travel Rule request before sending the crypto assets to the blockchain
Post-transaction Travel Rule: if your VASP as Beneficiary VASP, initiating a Travel RUle request after you received crypto assets from the blockchain

This /one-step API will run all verification flows in a synchronous way:

Address Verification(in pre-transaction situation)or TXID Verification(in post-transaction situation)
PII Verification.

If first check failed, Travel Rule process will be terminated right away and your counterparty VASP will not receive your encrypted PII payload.

Please note that, this API will always return HTTP Code as 200 and this API shall time out after 30 seconds.

Once you called /one_step API in a pre-transaction situation, you are required to invoke /notify_tx_id after you successfully execute this asset transfer on the blockchain. This will let your counterparty VASP receive a notification containing the correlation of txId and requestId.

Response Example 4: PII Verification Failed

HTTP Status: 200, VerifyStatus: 200003

{
  "verifyStatus": 200003,
  "verifyMessage": "PII Verification Failed"
}

Just to highlight, when you receive verifyStatus as 200003, it means PII payload sent by your VASP failed to be verified by your counterparty.

There could be various failure reason:

Specific PII field you sent is mismatched with their KYC data,
Certain PII Fields are not included in your PII Payload,
...

You can look into the verifyFields array in the response for the detail reason.
