Expanding a variable in a pipe

[@lbutlr]

I have the following:

| curl -s -d 'payload={"text":"${URL}"}' https://……

But the command is executed with the exact string ‘${URL}’, I assume because it is inside single quotes.

How do I expand this?

Try replacing your single ' with a double quote, the protect your inside
double quotes with backslashes:
curl -s -d "payload={\"text\":\"${URL}\"}" https://
