If you are an IATA agent, you can configure the platform with your own credentials. At the time of registration, you would have chosen your preferred airlines. Once you submit the request, there will be an email that you receive with the credentials as below.
For example, if you would like to configure Lufthansa:
Click on Add New
Choose Lufthansa, you will see a prefilled form as below.
All you will have to do is choose the POS from the dropdown, after which the API key and Secret Key will be auto filled. Then fill the fields that are empty by copy pasting the corresponding data from the email received and Save. Follow this process for other airlines as well.
