# EPIC FHIR Integration You can now integrate your app on [Epic FHIR](https://fhir.epic.com/) account with the Yellow.ai platform using OAuth. This will let your users access patient details, search for appointment slots, and book appointments. ## 1. Connect Yellow.ai with EPIC FHIR 1. Go to your **Epic FHIR** app and fetch the **Client ID** and **Client Secret**. ![](https://i.imgur.com/MGxkK8J.png) 2. Go to your cloud.yellow.ai bot and click **Integrations**. ![](https://i.imgur.com/BmIVufB.png) 3. Search for **EPIC FHIR**, fill in the **Client ID** and **Client Secret** and click **Connect to EPIC FHIR**. ![](https://i.imgur.com/bHEXvm6.png) :::note 1. Yellow.ai does not store the client’s credentials. We use the OAuth 2.0 approach to integrate with the client’s **Epic FHIR** account. 2. This integration supports the STU3 version of API, so the APIs based on the clients' use cases should be added while creating the **Epic** app. ::: ## 2.
