title: "Internal transfers"
---
To transfer funds between two [internal accounts](/platform/accounts/overview#internal-accounts), include the sender’s account id, customer id, and the recipient’s internal account id in your [transfer](/api-reference/transfer/post-v1-transfer) request. The `source` object contains the sender’s details, and the `destination` object contains the recipient’s details:

```bash title="internal transfer request"

     --header 'Idempotency-Key: 979879887678789_attempt_1' \
