What is an API Key?
If you want to use Sendlane’s API then you need to get your API Key. The API Key will let the other program know that it has access to to the calls.
To access your API Key you need to logon to your Sendlane account and click your account settings. Then scroll down a little bit and you will see a section titled “Security Credentials”.
There you will see the API & Hash key’s. Go ahead and copy and paste your API key into the appropriate field of the alternate program.
