HLR responses are requests that are sent to your platform through a GET request. The HLR API response itself will not contain any info for the HLR result. To obtain the result, you need to configure your HLR callback URL within the API settings here. Note: enter the full address (including http://).
Your platform should respond with a 200 OK HTTP header. When our platform doesn't receive a 200 OK header, we will try to deliver the receipt again (up to 10 times).
