In the latest release, Boomi has included a very important feature in the HTTP connector. The HTTP operation can now capture the value of the response header and store it into a dynamic document property. This is very useful as some of the applications require a certain cookie value returned in the first call to be used in the subsequent call.
To use this feature, you just need to:
1. edit a HTTP operation
2. scroll to Response Headers Mapping
3. add the specific response header that you want to capture
For more information, please refer to the official documentation.
