# Credential Resource

The Credential resource represents one credential record for a specific push notifications channel. Twilio Conversations supports the APNS, FCM, and GCM push notification channels. Each push notification channel vendor issues its own Credentials, and they can vary between vendors. The Credential resource allows you to save the Credentials that should be used for push notifications to a specific channel.

## Credential Properties

The Credential resource contains these properties:

```json
{"type":"object","refName":"conversations.v1.credential","modelName":"conversations_v1_credential","properties":{"sid":{"type":"string","minLength":34,"maxLength":34,"pattern":"^CR[0-9a-fA-F]{32}$","nullable":true,"description":"A 34 character string that uniquely identifies this resource."},"account_sid":{"type":"string","minLength":34,"maxLength":34,"pattern":"^AC[0-9a-fA-F]{32}$","nullable":true,"description":"The unique ID of the [Account](/docs/iam/api/account) responsible for this credential."},"friendly_name":{"type":"string","nullable":true,"description":"The human-readable name of this credential, limited to 64 characters. Optional.","x-twilio":{"pii":{"handling":"standard","deleteSla":30}}},"type":{"type":"string","enum":["apn","gcm","fcm"],"description":"The type of push-notification service the credential is for. Can be: `fcm`, `gcm`, or `apn`.","refName":"credential_enum_push_type","modelName":"credential_enum_push_type"},"sandbox":{"type":"string","nullable":true,"description":"[APN only] Whether to send the credential to sandbox APNs. Can be `true` to send to sandbox APNs or `false` to send to production."},"date_created":{"type":"string","format":"date-time","nullable":true,"description":"The date that this resource was created."},"date_updated":{"type":"string","format":"date-time","nullable":true,"description":"The date that this resource was last updated."},"url":{"type":"string","format":"uri","nullable":true,"description":"An absolute API resource URL for this credential."}}}
