INVALID_API_KEY

HTTP 401 · Invalid API key

What it means

The key is not one this API issued, or it was copied incompletely.

What to do

Copy the whole key, including the `ck_live_` or `ck_test_` prefix. A lost key cannot be recovered; create a new one.

Can I retry?

No. The same request will fail the same way until something about it changes.

Quote the request_id from the error if you contact us about it.
