Hi @Sirfyaad
- If I may, here is a suggestion:
a) when creating a post, the topic name should be the topic you are writing for, not “Not working need help”. You can imagine anyone writing here has something not working and need help too 
b) please give more context. “Expression all correct but trigger not working please help,” does not provide any relevant information that help us into providing help. We all are here on a voluntary basis: without context, we can’t guess what’s going on, and hence we can’t help you.
- Here is an excellent post I invite you to read:

- Now, about your question which, I think, is more “how to add line break in a post request”, here is my suggestion: can you replace this:
"text": "<<CONCATENATE(\"*We have received a new entry in the PhotoVideo team details are given below* \")>>\n
<<CONCATENATE(\" \")>>\n
<<CONCATENATE(\"DATE : \", [DATE])>>\n
<<CONCATENATE(\"TEAM NAME : \", [TEAM NAME])>>\n
<<CONCATENATE(\"PAIR QTY : \", [PAIR QTY])>>\n
<<CONCATENATE(\"HANDOVER QTY: \", [TOTAL QTY])>>\n
<<CONCATENATE(\"HANDOVER TO : \", [HANDOVER TO])>>\n
<<CONCATENATE(\"HANDOVER DATETIMES: \", [HANDOVER DATETIME])>>\n
<<CONCATENATE(\"UPDATE BY: \", USEREMAIL())>>\n",
with something close to this:
"text": "<<CONCATENATE(\"*We have received a new entry in the PhotoVideo team details are given below*,
"DATE :" , [DATE] , "
"TEAM NAME :" , [TEAM NAME] , "
"PAIR QTY :" , [PAIR QTY] , "
"HANDOVER QTY:" , [TOTAL QTY] , "
"HANDOVER TO :" , [HANDOVER TO] , "
"HANDOVER DATETIMES:" , [HANDOVER DATETIME] , "
"UPDATE BY:" , USEREMAIL()
)>>
- My suggestion may be inaccurate. About using line breaks with CONCATENATE(), please read this:
