FHIR connection with Postman and external systems

Hello, I have questions and issues with connecting the FHIR API to external systems and Postman. I have been reading the documentation but have not been able to get it to work in Postman before getting it to work in the external system. I look forward to your comments and assistance. Thank you.

The FHIR server by default is protected by SSL auth .
It can only be accesible by a client with valid certs ,part of its trust store.

see post here to disbale SSL for the HAPI FHIR in dev mode

Hello, I want to test Postman to generate electronic orders simulating an external system. I configured it to disable the SSL certificate, and it works correctly, but when I place the order, I get a 201 OK, but the order is not reflected in OpenElis, only in Postman with a GET.

The same thing happens with the POST for patients.

@Adrian It appears that the FHIR server is successfully storing the resources (since POST returns 201 and GET retrieves them), but they may not be processed into the OpenELIS core system.

You may want to check the following:

  • Are FHIR resources configured to trigger processing into OpenELIS (e.g., via a service layer or subscription)?

  • Are you posting the correct resource type expected by OpenELIS for order creation?

  • Does your setup require a transaction bundle instead of individual POST requests?

  • Are there any errors in the OpenELIS backend logs during the POST request?
