An API gives you access to your Osmek account outside of the system. You can find your API key by going to Account Settings inside Osmek. You can generate as many API keys as you need, and modify permissions for each, depending on what it needs to do.
1. Go to Account Settings
2. Manage API Keys
API Key Permissions
You can set permissions for each API key in your account, limiting access to individual content bins and/or API methods.
The allowed methods field can be "*" (an asterisk) for all methods, or a comma seperated list of API Methods.
When building your app, consider using different API keys for read only, and read/write operations, and different keys for different implimentations. See best practices for more tips.
