Hey Amy!

I'm happy to help. With this particular error, it means that the credentials that were entered are incorrect. I recommend typing in your credentials again, making sure to double-check spelling. I do this all the time, and it's luckily a quick and easy fix!

An access_token is a rotatable token specific to a single Item. It's used to access data for that particular Item. A public_token is a temporary token that can be exchanged for an access_token. It can also be used to initialize Link in update mode for an Item.

Here's a link to our handy docs if you want more information on these two tokens: plaid.com/docs/api/#glossary

I hope this helps resolve your issue! Please reach out if you have any additional questions. :)

Hey George,

I've looked over the error that you're receiving, and it looks like you're missing the "public_key" field in your request payload. Here's how to get access to your public_key: plaid.com/docs/api/#api-keys-and-access

I hope this sheds some light on this issue. Please let me know if you have any additional questions.
