How to combine two JSON in MULE? -

i have started working on mule , trying combine 2 jsons (say 1 coming http post , set payload in sub flow). how can combine 2 jsons.

i tried custom transformer no success.so please suggest how can implement or relevant reference doc same.

that depends on how getting payload different source ..

for example if using scatter-gather , getting payload 2 different source in parallel, can use <combine-collections-transformer doc:name="combine collections"/> or <collection-aggregator failontimeout="true" doc:name="collection aggregator"/> combine both json 1 payload..

this combine both json 1 payload
