Trying to retrieve a funding source balance via the API. Am able to receive a response from:
GET https://api.dwolla.com/funding-sources/{id}
but when I request the balance path, I get a not authorized message:
GET https://api.dwolla.com/funding-sources/{id}/balance
Exception: {“code”=>“Forbidden”, “message”=>“The supplied credentials are not authorized for this resource.”}
How can I authorize my API keys to access these resources?
Hi @Stephen_Donahue, that may be due to the funding-source being a Bank and not a Dwolla Balance. The API only supports retrieving the Balance of a Dwolla Balance.
If it is, in fact, a Balance funding-source that you were trying to retrieve the balance of, for which you getting the errors, please let us know!
@shreya - So what I am hearing here is that using the API, I cannot get a balance from a bank account that is not a Dwolla FBO account. Is that true?
If it is, then, what happens if I attempt to do an ACH transaction from a non-dwolla account and there are not enough funds in it to transfer out?
Also, when I am in the sandbox dashboard, for the non-dwolla bank account, I cannot determine how much is in it. I can only see the transactions that supposedly put money in that account.
Thanks
Dave
Hi @dgreenly - That’s correct. We don’t have the ability to fetch an external bank account’s Balance in the API.
If a transfer is made from a bank account that doesn’t have insufficient funds, it would fail with an R01 ACH return after it has been exported from Dwolla. These return codes are documented in our Developer Docs along with the actions Dwolla takes upon receiving them. You can also test these transfer failure scenarios in Sandbox.
For the Dwolla Balance in you Sandbox Master Account, you should be able to view the total Balance in the Dashboard and also via the API.
Here’s a screenshot of the Dwolla Balance in the Dashboard -
is this still the case? I mean to ask can dwolla still cannot fetch account balance from users checking account? How else does dwolla recommend ways to reduce ach return codes.
Hi @jasan – that’s correct. We do not have the ability to fetch a Bank’s balance via the Dwolla API.
One way you could check a User’s balance before creating a transfer is by utilizing a third party bank authentication provider, like Plaid Balance. Dwolla also has a tokenized integration with Plaid Auth for adding verified funding-sources which can be utilized in tandem with their Balance API.
Hope that helps!
