Whether you're a on a standard plan or using a White Label, you'll need to sign up as a developer on Gelato to receive your API Key and Application ID so that you can access our restful API.
When signing up for a developer account on Gelato, you should use an email address linked to an admin on your account to receive the related API Key and Application ID.
If you don't use an email address which is already linked to a Sendible or White Label account, the system will automatically create a 'developer' type account for you with limited access to services, etc.
You can sign up for an account on Gelato on this page.
Full documentation on our API is provided once you've signed up for an account.
