52002: Invalid Credential Sid

In order to send push notifications to iOS and Android devices you need to configure a Credential that allows Twilio to send notifications to your app.

You can configure these at different places depending on which Twilio product you use:

• Chat: Configure in access token
• Notify: Configure default Credential in Notify Service or Binding specific one in Binding
• Voice SDK: Configure in access token

• Credential SID is not configured correctly

• If using Chat include Credential SID in access token. Check out this guide
• If using Notify, either configure default Credential SID in your Service or provide the Credential SID in the Create Binding request
• If using Voice SDK, include Credential SID in access token. Check out our documentation for details
