This could have happened by:

putting in the wrong API keys
or putting in the Secret Keys in place of the Public Keys.

How to resolve this

Simply go to your dashboard settings and click on the API Keys & Webhooks tab.
Copy your API keys, noting the Public and Secret Keys (Live Keys if your website is Live).
Replace them on the Payment Settings on your website or app, taking care to place the correct key in the correct field.
If you're using the API, ensure only the pk_domain_xxxxxx part of the public key is used. Do not append anything to the string.

Sorry you didn't find the answer you needed 😢
