Restricted API Keys, Conversations (classic) permissions

Restricted API Keys now support granular, resource-level permissions for Conversations (classic), covering actions like listing conversations, sending messages, managing participants, and configuring webhooks. This lets you scope a key to only the operations your integration needs — for example, granting read access to conversations while blocking any ability to delete users or roles — reducing the blast radius if a key is ever compromised. Configure these permissions when creating a Restricted API Key in the Twilio Console.
