Check Duplicate

### Check for duplicate customer applications. **Available to:** Organization administrators **Environments:** Live **[Rate Limit](/overview/core-concepts/rate-limits):** No endpoint-specific limit Check whether similar customer applications already exist before submitting a full subaccount request with [`createPartnerSubAccountRequest`](/api/rest-api-endpoints/users/create-partner-subaccount-request). This can help you avoid duplicate application rejections by catching conflicts early. All fields are optional. Provide any combination of `userId`, `taxIdentifier`, `nationalId`, `countryCode`, and `organizationId` to narrow the search. The response returns `ok: true` if no duplicate concern was found, or `ok: false` if potential duplicates exist. **Related Endpoints** - Use [`createPartnerSubAccountRequest`](/api/rest-api-endpoints/users/create-partner-subaccount-request) to submit a subaccount request after confirming no duplicate exists.
