@HR3 - Can you post what an example request with API key look like? Please do not use the actual API key in the example.

When we have similar issue I use a URL encoder.

Try entering your full URL here:

Then use the encode feature to covert it to a format that Flow will like.

@HR3 , you just need to specify the API Key parameter name i.e. text 'rest_api_key'. Since there is an equal sign, shouldn't the parameter location be 'query parameter' instead of 'header'? That is the reason I requested an example request message that will be accepted by the REST service.

This page provides some help on setting up the API Key authentication. The actual key will be specified on creating a new connection, as in here. This ensures that same custom connector can be used to connect to the REST service with different API keys in different Flows.

Please reply back if you have any questions.
