Challenge 2: A client is reaching out with a question about a particular error. Hi Plaid Support, I have a user that is complaining that they cannot link their account to First National Bank. The error they get back is INVALID CREDENTIALS. They are _ claiming that they are typing in the correct information. Are there any troubleshooting steps that my user can take? Thanks, Ernie Hudson

Challenge 3: A client is reaching out with a question about implementation. Hi Plaid Support! We were surprised to find out that Plaid allows a user to link the same Item multiple times. We’d like to prevent this from happening. Don’t your docs say that you block this kind of thing? How can we prevent users from linking the same account multiple times? Your Friend, Bill Murray

Challenge 4: A client is reaching out with a question about transactions data. Hi Plaid, I’m recently integrated with Plaid and I’m starting to see duplicate transactions pop up in my database. The pattern seems to be that Plaid returns each transaction and then returns that same transaction again roughly two days later but under a new transaction _ id. Could you please take a look at let me know what’s going wrong here? Here is one example of the duplicates I’m seeing: { "account id": "vokyE5Rn6vHKqDLRXEn5fne7LwbKPLIXGK98d" _ "amount": 2307.21, "iso code": "USD" , , currency _ "unofficial _ currency code": null, _ _ "category": [ "Shops" , "Computers and Electronics" ], "category id": "19013000" _ "date": "2017-01-29" , , "location": { "address": "300 Post St" , "city": "San Francisco" "region": "CA" , "postal code": "94108" , _ "country": "US" , "lat": null, , "lon": null }, "name": "Apple Store" , "payment meta": Object, _ "pending": false, "Pending transaction id": _ _ “lPNjeW1nR6CDn5okmGQ6hEpMo4lLNoSrzqDje” null, , "account owner": _ "transaction "transaction id": "4WPD9vV5A1cogJwyQ5kVFB3vPEmpXPS3qvjXQ" _ type": "place" _ , }, { "account id": "vokyE5Rn6vHKqDLRXEn5fne7LwbKPLIXGK98d" _ "amount": 2307.21, "iso code": "USD" , , currency _ "unofficial _ currency code": null, _ _ "category": [ "Shops" , "Computers and Electronics" ], "category id": "19013000" _ "date": "2017-01-27" , , "location": { "address": "300 Post St" , "city": "San Francisco" "region": "CA" , "postal code": "94108" , _ "country": "US" , "lat": null, , "lon": null }, "name": "Apple Store" , "payment meta": Object, _ "pending": true, "pending transaction _ "account id": null, _ "transaction "transaction _ owner": null, id": "lPNjeW1nR6CDn5okmGQ6hEpMo4lLNoSrzqDje" _ type": "place" _ } , Best, Janine Melnitz
