Create Additional API Key
Note: Each account can store up to 15 unique API Keys
An API key is a 96-character GUID that serves as a secure credential for accessing your account and making API calls outside of the user interface. Every API call requires this unique key, which is distinct from the credentials used for SMTP relay communication.
New accounts don't contain any pre-generated API keys. To create a new key, simply click the button below:
At this stage, you can configure custom permissions for the API key and define optional access restrictions. These restrictions limit the API key's functionality to a specific IP address or range, as specified in the designated field.
After clicking the "Create" button, a popup will display your newly created API key. Be sure to copy and save it in a secure location, as you will not be able to retrieve it once the window is closed. For security purposes, the system will obfuscate the key after creation, showing only the last five characters.
You can create additional API keys as needed. This can be particularly useful if you need to share a key with someone while assigning different permissions for its use.
Manage API Keys
This screen contains every API Key that was already created. You can modify their properties or delete them here.
Edit
This option will allow you to change the details of your API Key like permissions or name.
Change API Key
This will generate a new API Key for the particular credentials you chose. This way only the API Key will be changed and the permissions you chose for it will stay the same. This is the only way to regain access to this particular credential if you somehow misplaced the key.
Delete
This option allows you to delete an API Key that you no longer need.
