In order to use Shelterluv's API, you must generate an API key. You can do so via Configuration from General Shelter > Uploads and Integrations > My Organization's Website.
To generate a new key, use the blue "Generate New Key" option. Then you'll be asked if you'd like to add a description for the key. This is just to label the API for your reference later, so that you know which key has been used for what purpose.
To disable or delete an existing key, use the red "Revoke" option.
You now have the ability to generate multiple API keys. This will be useful for you if you'd like to use the API in multiple ways. For example, perhaps you want to use the API for your website AND Maddie's Pet Assistant. You can create a separate API key for each.
