Picnic does not accept deposits initiated through external apps (ACH Pull).
What is ACH Pull
This is when you try to use your dollar account details at another bank or brokerage to "pull" money from there to your Picnic account.
This method works like a pre-authorized or automatic debit on a third-party platform.
Understand the difference
ACH Push (supported): you initiate the transfer from your bank/brokerage to Picnic.
ACH Pull (not supported): the brokerage/bank tries to withdraw to the Picnic account as if it were an automatic debit
Frequently Asked Questions
Will ACH Pull work in the future?
We are always improving the experience, but at the moment ACH Pull is not supported.
Can Picnic "manually authorize" a pending ACH Pull?
No. Since this type of debit is not supported, there is no way to manually approve a Pull attempt.
Is Direct Deposit Push or Pull?
It is usually Push (Credit), as it is a transfer to the account (inbound). However, the name may vary by institution.
