Throughout the ISA transfer lifecycle, Upvest sends webhook events to notify you of progress at each stage. Monitor these webhooks to track transfer discovery, instruction submission, processing, and settlement completion.
The ISA_TRANSFER.* event type notifies you of changes to an ISA transfer's lifecycle.
| Event | Trigger | When It Fires |
|---|---|---|
ISA_TRANSFER.NEW | ISA transfer is initiated. | Immediately when POST /account_transfers completes successfully. |
ISA_TRANSFER.DISCOVERY | Discovery phase begins. | When the ceding provider receives and acknowledges the transfer request (external transfers only). |
ISA_TRANSFER.DISCOVERY_CONFIRMED | Discovery phase completes. | When the ceding provider confirms transfer details and accepts the transfer (external transfers only). |
ISA_TRANSFER.INSTRUCTED | Transfer instruction sent. | When the transfer instruction is prepared and sent to the ceding provider. |
ISA_TRANSFER.PROCESSING | Transfer is processing. | When the ceding provider confirms receipt and begins processing the transfer. |
ISA_TRANSFER.SETTLED | Transfer settlement complete. | When the transfer is complete and funds have been received. |
ISA transfers follow distinct phases depending on transfer type (internal or external):
NEW → INSTRUCTED → PROCESSING → SETTLED- NEW: Transfer request received
- INSTRUCTED: Transfer instruction processed
- PROCESSING: Transfer execution in progress
- SETTLED: Transfer complete
NEW → DISCOVERY → DISCOVERY_CONFIRMED → INSTRUCTED → PROCESSING → SETTLED- NEW: Transfer request received
- DISCOVERY: Discovery phase started with ceding provider
- DISCOVERY_CONFIRMED: Ceding provider accepts transfer
- INSTRUCTED: Transfer instruction sent to ceding provider
- PROCESSING: Ceding provider processing the transfer
- SETTLED: Transfer complete and funds received
Note: DISCOVERY and DISCOVERY_CONFIRMED phases are only relevant for external transfers. Internal transfers skip directly from NEW to INSTRUCTED.
When an ISA transfer is initiated, you receive an ISA_TRANSFER.NEW event:

}Use webhooks to track ISA transfer progress automatically:
Set up webhook listener
Configure your webhook endpoint to listen for ISA transfer events. See Implementing webhooks for setup instructions.
Subscribe to ISA_TRANSFER.* events.
Initiate a transfer
Create an ISA transfer via POST /account_transfers. You receive an ISA_TRANSFER.NEW event immediately.
Monitor discovery phase (external transfers)
For external transfers, wait for ISA_TRANSFER.DISCOVERY and then ISA_TRANSFER.DISCOVERY_CONFIRMED events. Internal transfers skip this phase.
Monitor instruction phase
Wait for the ISA_TRANSFER.INSTRUCTED webhook event indicating the transfer instruction was sent to the ceding provider.
Monitor processing phase
Monitor for the ISA_TRANSFER.PROCESSING webhook event indicating the ceding provider has begun processing the transfer.
Wait for settlement
Monitor for the ISA_TRANSFER.SETTLED webhook event indicating settlement is complete. Do not poll the transfer status endpoint; wait for the webhook instead.
Update user interface
Use the webhook stream to update your application's transfer status display in real time. Once ISA_TRANSFER.SETTLED is received, confirm successful transfer completion to the user.
