Hi! I’m getting `400 Bad Request` error on linkTokenCreate endpoint at production  
`Request ID k4V6K6HFdqJQ4qG`

Unfortunately logs do not show details. The same code base works on the sandbox environment as expected.

Could you pleas provide a clue what could be the reason.

Thanks in advance

Best,  
Dmitry

Hi @Dmitry_Ostromogilski – did you mean you are attempting to call [Plaid’s token endpoint](https://plaid.com/docs/api/tokens/)? If so, I’m afraid I wouldn’t be able to help out much. I did find [this](https://plaid.com/docs/errors/invalid-request/#invalid_configuration) in their docs that might be helpful to reference:

> Verify that all field names being provided to [`/link/token/create`](https://plaid.com/docs/api/tokens/#linktokencreate) match the schema for that endpoint. In particular, when migrating from Link tokens, note that some field names have changed between those used for Link token style Link configuration and those used as parameters for [`/link/token/create`](https://plaid.com/docs/api/tokens/#linktokencreate).

I’d recommend reaching out to Plaid’s support team with the above details you shared if you need further assistance.

Thank you for taking the time to review my issue! I’ll contact Plaid’s support immediately.
