Hi @Mohsen Akhavan ,
Thanks for using Microsoft Q&A forum and posting your query.
Since Function1 send data every 5 mins, I would suggest to write the body to a storage blob location and use Storage event trigger feature in ADF to trigger your ADF pipeline. Inside the pipeline before your Function2 have a lookup activity to read the data of the response body (in blob) from Function1 and pass the output of lookup to your Function2.
Hope this info helps. Do let us know if you have further query.
