The key in the code is not valid
Code: key_invalid
The key in the code does not exist, has a typo, or was revoked.
How to fix it
- In the dashboard open your venue, Online booking, On your website.
- Copy the code with Copy code.
- Replace the whole old code on the page with it, and publish the page.
For developers: the API also answers with this code when a request carries no valid key or dashboard sign-in.
