# Update KYC Submission

> Update an existing KYC or KYB submission with corrected or additional information

Update a previously submitted KYC or KYB record. Use this endpoint when a customer needs to correct information or provide additional documents — typically after a rejection. Only include fields you want to change.

```
PUT https://api.yativo.com/api/v1/customer/kyc/update
```

<Note>
  Include an `Idempotency-Key` header on every request. Supply `customer_id` and `type`, then any fields you want to update. Fields not included are left unchanged.
</Note>

## Request body

<ParamField body="customer_id" type="string" required>
  The UUID of the customer whose KYC you are updating.
</ParamField>

<ParamField body="type" type="string" required>
  `"individual"` or `"business"` — must match the original submission type.
</ParamField>

All other fields from the original submission schema can be included to update their values. See [Submit Individual KYC](/fiat-api-reference/kyc/submit-individual) or [Submit Business KYC](/fiat-api-reference/kyc/submit-business) for the full field reference.
