Using REST API to retrieve data from another system

Hello all,

I work for a school and we have a hudge project to automate our business processes (more than 200!). According to the fact that our school use Office 365 for our studends and teachers, we decided to use Visio to describe our processes (BPMN) and Microsoft PowerApps & Automate to automate them.


For some of our processes, I'll have to retrive data from another system which stores all our students, teachers, courses, subscriptions, notes, etc .. information. This system has a collection of REST API but... and this is my problem, it seems I can't use them to retrieve some data because :


- The security to access this system use a TLS 1.2 system communication with a certificate I received.

- The postman collection is the version 2 and it seems that connectors of PowerApp are only compatible with version 1


So, it is possible, somewhere, to install the certificate I received to use it when trying to communicate with my system ?

I used a system to convert my postman collection into an OpenAPI collection. It seems it could use it to make my requests to my system, but first I need to solve the use of my certificate and the TLS 1.2 protocol.


Do you have an idea about that ..or is it not possible to use the REST API functions to retrieve my data ?

Thanks very much for your help and sorry for my bad english ...

Best Regards
