The function of an HTTP Transformer is to interact with an API end-point with the implementation of an entity transformer. This can be used to collect data from an endpoint based on previously obtained data.
Here’s how to do it.
Step 1: Click on Add Data Transformer and select the Key Filter transformer.
Step 2: Fill the Request URL section.
Step 3: Fill the Request Method.
Step 4: Select the HTTP Client.
Step 5: On clicking the Run Test button, you will see that the transformer has pulled the specified data.
Note: While utilizing an HTTP transformer, the data retrieved from the HTTP transformer becomes the new reality. In effect, it means that the previous data is no longer reflected in the Entity Data.
(To prevent this from happening a Merger Transformer can be implemented to merge data together.)
