Creating a new subuser through SendGrid's API is a multi-step process. This guide will walk you through the necessary steps in order to create a new subuser account using only API calls.
With the subuser creation API call you will be able to establish the new subuser's account and profile settings. This call will create the new subuser account, however it does not apply the sending IP for the account, nor does it establish a domain authentication entry or enable website/SMTP access for the subuser.
Now that you have created the new subuser account, you will need to add an IP so that it can send emails. We advise that you first find an available IP for this subuser. You can do so by using the following call:
When defining the parameter 'list' there are a few options you can choose:
Available - Will list all of the unassigned IP addresses for the account. If a subuser is deactivated _and it _is assigned an IP, that IP will show up on this list since that IP address is not technically in use.
After you have selected the IP that you wish to assign to your subuser account, simply make the API call to append the IP address.
When defining this call's 'set' parameter, you have a few options for appending the subuser's IP:
Specify - Specify the IPs to the subuser
After you have created the subuser account and have appended an IP address, you are now ready to assign an existing authenticated domain to the account. If you have not yet created the required records for authenticating your chosen domain then this step should be skipped.
First, you should find out what authenticated domains you have associated with your account. This call will list your available authenticated domains:
The API response above shows that email.sendgrid.com and email.example.com are both already established domain entries, and can be used by this subuser. If none are displayed then the next step in this process should be skipped.
If you have an authenticated domain entry that you wish to apply to your subuser then you will need to append the whitelabel entry to your subuser:
The final step in creating your new subuser requires you to simply activate the subuser account so that they have website and SMTP access.
