What is an Omnisend API key? An Omnisend API key is a unique credential generated in your Omnisend account that allows Upstack Data to securely access and interact with your Omnisend data. It is a long alphanumeric string, typically structured as a 64-character secret followed by a - and a short identifier (for example, xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-xxxxxxxxxx).

​
