Hi,

How can I get a webhook call back after a transfer is complete in sandbox?

Also can you enable my ach addenda in sandbox for [ge\_li@hotmail.com](mailto:ge_li@hotmail.com)?

Thanks

Hi @l0ge0001

Your ach addenda for sandbox has been enabled 😊

To obtain a [webhook](https://docs.dwolla.com/#webhooks) after a transfer, you must first create a [webhook subscription](https://developers.dwolla.com/guides/webhooks/create-subscription#step-1-create-a-webhook-subscription)

Thanks Kelly,

I already created the webhook subscription. After created transfer transaction in sandbox, it is always pending status. I can’t test the “processed” status changing webhook callback.

Oh I see. There are two ways to process pending transfers in sandbox, @l0ge0001 .

You can either hit the “Process BankTransfers” button in the sandbox dashboard, found in the header
