Use case
Merger transformer helps in combining data pulled from a source with the current data (both being wrapped within an entity data).
For this example, let’s use a merger transformer in combination with a HTTP transformer. You can refer to what we had discussed under HTTP Transformer (refer point 8).
Guide
Here’s how you can add a merger transformer.
Step 1: You have to temporarily remove the HTTP transformer first.
Step 2: Select Merger Transformer under Data Transformers.
Step 3: Now select a HTTP Transformer under it, and follow the same steps mentioned in point 8 (above).
Step 4: Fill in the field of Template. If you want to merge both data under an object with a new key, mention the key. For example, “xxxx” : “&{@}”.
Step 5: On clicking the Run Test button, you can visualize that the previous data has been recorded. It’s followed by the new key xxxx containing the object obtained from the merger transformer.
