Hi,  
When I get the “customer\_verified” webhook from Dwolla, I’m saving the verfiied user’s balance funding source by calling /\<customer\_link\>/funding-sources/ endpoint.

In the sandbox environment, I am finding that sometimes the balance funding source is listed under the embedded links returned, and other times not. I am guessing there’s a race issue, because I do see the balance funding source created in the dashboard regardless. Is this a known bug? How do I get around this problem? Is there a webhook that gets fired when the balance funding source is available?

Many thanks,  
Will

Hi @dubc, Thanks for posting! The balance funding source is attached when the Customer has a verified status. Perhaps, you’re retrieving the customer’s list of funding sources prior to the account completing the identity verification process? Do you have an example request (timestamp, x-request-id header, etc.) where we could take a look to see if this may be the case?

Thanks for the reply.  
I just tried five times in a row and couldn’t repro — but it was happening once every 2-3 times or so for me on Jun 24-25.

The request to retrieve funding sources was happening after the “customer\_verified” webhook was receive, and so the customer was definitely verified. My guess is that there’s a race condition where the balance funding source can be created slightly after the user verification.

I’ll update again if we repro.

Hi I just repro’ed this again.  
Response from AFTER ‘customer\_verified’ webhook:

{  
“\_links”: {  
“self”: {  
“href”: “[https://api-sandbox.dwolla.com/customers/](https://api-sandbox.dwolla.com/customers/){id redacted}/funding-sources”,  
“type”: “application/vnd.dwolla.v1.hal+json”,  
“resource-type”: “funding-source”  
},  
“customer”: {  
“href”: “[https://api-sandbox.dwolla.com/customers/](https://api-sandbox.dwolla.com/customers/){id redacted}”,  
“type”: “application/vnd.dwolla.v1.hal+json”,  
“resource-type”: “customer”  
}  
},  
“\_embedded”: {  
“funding-sources”:   
}  
}

Timestamp is at 2020-07-07T23:35:28.263Z UTC.  
I’m using dwolla-v2 nodejs module to make the request. Not sure what other information can be gathered from that.
