Hi @nicodumans, thanks for reaching out!

I notice you receive `Invalid API Key`, did you replace `YOUR_API_KEY` with a API Key created on the [Nylas Dashboard](https://dashboard-v3.nylas.com) for the specific application?

The API Key value will start with something like `nyk_`

@ram  
I am getting the same problem in the sandbox app

I did replace the “YOUR\_API\_KEY”, I tried replacing manually, also the UI replaces it automatically (there is even a comment at the top of the code snippet in the UI saying they did it for me)  
I tried regenerating the api key and replacing again  
recreating the app  
recreating the grant

nothing worked, any clues?

EDIT: It worked when I recreated the app with USA data residency, this isn’t good for me because I work in Europe, you should probably check this out

Hi @guyh, thanks for sharing, just to clarify your comment:

> EDIT: It worked when I recreated the app with USA data residency, this isn’t good for me because I work in Europe, you should probably check this out

Were you using an US Region `Nylas API Key` with the EU [Nylas API URL](https://developer.nylas.com/docs/dev-guide/platform/data-residency/) (`https://api.eu.nylas.com`)causing the error?
