Hello

We have a process flow where we want to check if an user_id exists in IAM.

In order to do this we created a Web Connection with the proper Endpoint, however it didn't go as planned because even if in Postman the calls (with the same user & pass) are working

When we try with Web Connection or Http Connector, it is failing with status -23 (web connection) and -7 (http connector) and the following error on error log

In the past we identified that Postman was auto-calculating the "Host” header on the call, we solved the issue by explicitly provide it in the headers, but now seems that is not enough.

Did you encountered this or have any idea how we can solve this issue?

Hi ​@Ionut,

This method of communicating with IAM I discourage. We offer a native Application connector which can be used to communicate with any application present within the IAM database; which includes IAM itself.

No such host looks to me like Indicium is unable to find the host name, maybe because it cannot find it by the name. Perhaps the IP address would work, but then again, the Application connector would be a better choice.

Alternatively, if the IAM you want to reach is not a valid target for the Application connector, I advice to use a Web connection. This is a more future proof way of communicating with any endpoint out of the web.

We are currently working on a better way of interacting with the IAM database using process actions, such as creating a user. Until then, the Application connector or Web connection is the way to go.

@Mark Jongeling Hi, we tried also with Web Connection and directly specify the IP address, but the result is the same, we'll check Application Connector.
