# Programmable Chat API Credential Resource

> \[!CAUTION]
>
> Programmable Chat has been deprecated and is no longer supported. Instead, we'll be focusing on the next generation of chat: Twilio Conversations. Find out more about the [EOL process here](https://www.twilio.com/en-us/changelog/programmable-chat-end-of-life-notice).
>
> If you're starting a new project, please visit the [Conversations Docs](/docs/conversations) to begin. If you've already built on Programmable Chat, please visit our [Migration Guide](/docs/conversations/migrating-chat-conversations) to learn about how to switch.

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

You can learn more about provisioning vendor-specific credentials in these topics.

* [Configuring iOS push notifications](/docs/notify/configure-ios-push-notifications).
* [Configuring Android push notifications](/docs/notify/configure-android-push-notifications)

## Twilio Console

You can also manage the Credentials for Programmable Chat in your [Twilio console when you are logged in](/console/chat/credentials).

## Credential Properties

Each Credential resource contains these properties.

```json
