# Electronic Health Record (EHR) integration
If you're developing an EHR and are looking to integrate with Nabla, you may pick one of the strategies below.
[Get in touch](https://www.nabla.com/copilot-contact/) if you wish to discuss your use case in more detail.
| Method | For | Pros | How |
| ------------------------------------------------- | ------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Front-end integration | Web-based EHRs | Simple and straightforward flow, great for proof-of-concept and simple integrations.
No need to set up the Nabla Core API.
Ability to leverage the existing Nabla UI. | Using the Nabla Assistant [Chrome extension](https://chrome.google.com/webstore/detail/nabla-copilot/gdhbaoemgglcgmkidhnhcellgnehaeol).
On your EHR domain, you may request the "Copy" button from the extension to be replaced with an "Export to ``" button. In that case, Nabla Assistant will export the generated note and structured information via JavaScript.
The EHR web app should listen to `window` events to receive the required information when the button is clicked, and fill the right fields in the EHR (see example below). |
| Back-end integration (through the Nabla Core API) | All EHRs including ones available on mobile apps | For deep UI integration.
Highly customizable. | Server-side integration using Nabla APIs. |
Example of message you can receive in the Front-end integration
