Restricted API Keys
Public Beta Notice
Restricted API Keys are currently available as a public beta release. Some features are not yet implemented and others may be changed before the product is declared as Generally Available. Beta products are not covered by a Twilio SLA.
Learn more about beta product support.
Restricted API Keys allow you to decide which Twilio API Resources an API Key can access, and which action(s) the API Key is allowed to take on those API Resources.
Restricted API Keys currently allow you to grant API access to specific Studio, Voice, Messaging, Long Codes, Regulatory Compliance, and SIP endpoints. Please note, we are actively adding more permissions to this product.
For example, if your Programmable Voice application's testing suite makes test Voice calls, you can create a Restricted API Key that is only permitted to send POST requests to create Call Resources.
Or you can create Restricted API Keys that provide your engineering team with access to every Voice endpoint except the Call Recording Resource endpoints.
Warning
Currently, you cannot create Access Tokens for Twilio's client-side SDKs if you're using Restricted API Keys.
Complete the following steps to create a Restricted API Key.

Duplicating a Restricted API Key is a convenience feature that allows you to easily create a new Restricted API Key with the same permissions as another Restricted API Key. You can then modify the Friendly name and permissions with the new Key.

Restricted API Keys allow you to select specific API endpoints that the Key is authorized to access. Currently, you can grant these permissions for Studio, Voice, Messages, Long Codes, and SIP endpoints.
Each permission maps to one or more endpoints/actions for each API Resource.
