# Simulate transfer state change

Changes the transfer status to the specified state. The available state transitions are:

- processing — from incoming_payment_waiting
- funds_converted — from processing. Refer to regional guides for special regional requirements.
- outgoing_payment_sent — from funds_converted
- bounced_back — from outgoing_payment_sent
- funds_refunded — from bounced_back. Will not trigger a refund webhook.

{% admonition type="warning" %}
Simulation does not work with email transfers.
{% /admonition %}

{% admonition type="warning" %}
You need to fund the transfer before calling simulation endpoints. Calling the processing endpoint is required even after the funding call has changed the transfer state to processing automatically.
{% /admonition %}

{% admonition type="info" %}
While transfer state simulation calls will respond with 200 in real time, the process internally is asynchronous. Please ensure you give at least 5 seconds in between simulation calls.
