Assuming the string is stored in a variable $s.

Is it the only number? Then

grep -Eo '[[:digit:]]+' <<< "$s"

would work.

Or using a Bash regex:

re='request id ([[:digit:]]+)'
[[ $s =~ $re ]]
echo "${BASH_REMATCH[1]}"

You need to use grep -oE '[0-9]*' on string, like:

data="requested producer access with request id 2563 to product exampledomain.test-dev.test.nonprod.com for user : test-user on product test-product-validation-required"

echo $data | grep -oE '[0-9]*'

Output: 2563
