ACH transfer API error

When I bank to bank transfer money Customer to Admin using ACH process, then error is showing like below:
So how can I check the bank balance of a customer?

Can you provide an API like that or suggest how to implement it?

Hi @shraddha_testing – Dwolla isn’t able to check the balance of a Bank funding-source. However, you can utilize Plaid’s API to do so!

We also have an integration with Plaid which lets you add Plaid verified banks to Dwolla.
