By default InterSystems IRIS expose your endpoints using http, but can be necessary run https from your dev env and/or get public internet access to your app. You can buy or get a certificate and config a gateway, spending many hours or use a great public service called ngrok. Follow the steps: **1 - Run your app, I will use FHIR template as sample, see:** 1.1 download the app: git clone https://github.com/intersystems-community/iris-fhir-template.git 1.2 go to the app dir: cd iris-fhir-template 1.3 run the app: docker-compose up -d 1.4 get access to the endpoint from postman or other api client: http://localhost:32783/fhir/r4/Patient/1 **2 - You can see the endpoint runs only localhost and using http. Now we use ngrok to resolve this:** 2.1 - Access , create a free account and login in the ngrok. You can see many options, including use ngrok into your yml files. 2.2  - Into ngrok go to Setup & Installation () and download the ngrok specific to your OS. 2.3 - Unzip the file to your app root path (or any path, like your applications folder). 2.4 - Authenticate your client to the ngrok server using instructions in the Authentication > Your Authtoken (). In my case (windows) I ran:
ngrok.exe authtoken 1iCGsc8NEmHTjfe43wmqavSHT2y_7T......... 
2.5 - Ngrok save your authtoken in your home directory, so next times will be not necessary authenticate again, only use the service. 2.6 - Now, you need to know your http port, in my case is 32783 (http://localhost:**32783**). Run:
ngrok.exe http 32783
2.7 - You can see your public https or http address to your endpoint: ![NGROK prompt](/sites/default/files/inline/images/images/ngrok.png) 2.8 - Test your new endpoint in the postman or any rest client, in my case https://9ec669d2221b.ngrok.io/fhir/r4/Patient/1. 2.9 - Ngrok give you many other use case scenarios (webhook, ssh, etc), see: [https://dashboard.ngrok.com/get-started/tutorials.](https://dashboard.ngrok.com/get-started/tutorials)
