cURL using bash script with while read text file - bash

Question

Hi there anyone there having the same trouble like mine?
whenever I cURL the $list from the list.txt it just displaying {} which is a blank response from the API does my code should be really working properly or it is just a bug?
I know the $list is working because I can update the database status
Please this is a bit urgennnnttt :(
#! /bin/bash
filename=/var/lib/postgresql/Script/list.txt
database='dbname'
refLink='URL'
authorization='Authorization: Basic zxc'
expireDate=$(date -d "+3 days")
body="Message."
while IFS=' ' read -r list
do
wow=$(curl --location --request POST $refLink \
--header 'Authorization: Basic $authorization' \
--header 'Content-Type: application/json' \
--data-raw '{
"title":"Expiration Notice",
"body":"$body",
"min" :[{"mobileNumber" : "$list"}],
"type" : "Notification",
"action_type" : "NotificationActivity"}')
echo "result: '$result'"
RESP=$(echo "$result" | grep -oP "^[^a-zA-Z0-9]")
echo "RESP:'$RESP'"
echo $body
#echo $wow >> logs.txt
psql -d $database -c "UPDATE tblname SET status='hehe' WHERE mobile='$list'"
done < $filename

Your "$list" JSON entry is not populated with the content of the $list variable because it is within single quotes of the --data-raw curl parameter.
What you need is compose your JSON data for the query before-hand, preferably with the help of jq or some other JSON processor, before sending it as argument to the curl's POST request.
Multiple faults in your scripts (not exhaustive):
Shebang is wrong with a space #! /bin/bash
expireDate=$(date -d "+3 days") return date in locale format and this may not be what you need for your request.
The request and the response data are not processed with JSON grammar aware tools. grep is not appropriate for JSON data.
Some clues but cannot fix your script more without knowing more about the API answers and functions you use.
Anyway here is how you can at least compose a proper JSON request:
#!/usr/bin/env bash
filename='/var/lib/postgresql/Script/list.txt'
database='dbname'
refLink='URL'
authorization='zxc'
expireDate=$(date -R -d "+3 days")
body="Message."
while IFS=' ' read -r list; do
raw_json="$(
jq -n --arg bdy "$body" --arg mobN "$list" \
'.action_type="NotificationActivity"|.title="Expiration Notice"|.type="Notification"|.body=$bdy|.min[0].mobileNumber=$mobN|.'
)"
json_reply="$(curl --location --request POST "$refLink" \
--header "Authorization: Basic $authorization" \
--header 'Content-Type: application/json' \
--data-raw "$raw_json")"
echo "json_reply: '$json_reply'"
echo "$body"
# psql -d "$database" -c "UPDATE tblname SET status='hehe' WHERE mobile='$list'"
done <"$filename"
