Create a withdrawal to an external bank account.

Withdrawal Types:

• Withdraw to Self: Use external_account_id from the External Accounts API
• Send to Others: Use external_account_id from a Recipient's bank account

The system automatically detects whether the bank account belongs to the customer or a recipient based on the external_account_id.

If destination_address_id is an External Account ID, then the asset, network, and country_code here should remain consistent with the External Account ID.

Sandbox Simulation

In sandbox environments, you can simulate different withdrawal states by appending a suffix to the Idempotency-Key header:

Example:

• Normal: Idempotency-Key: 550e8400-e29b-41d4-a716-446655440000
• Simulate failure: Idempotency-Key: 550e8400-e29b-41d4-a716-446655440000:FAILED
• Simulate pending: Idempotency-Key: 550e8400-e29b-41d4-a716-446655440000:PENDING

Important: When querying by idempotency_key, you must use the full key including the suffix. For example, if you created a withdrawal with 550e8400-e29b-41d4-a716-446655440000:FAILED, you must query with the same full key. Using only the UUID part will return 404 Not Found.

Note: Simulation suffixes are only available in sandbox environments and will be ignored in production.
