My site is not receiving rewards. What should I check?

Start with your placement's Postback log. It lists every notification we sent and what your server answered.

The usual causes:

• Your server is asleep. Free hosting plans often pause after inactivity and take too long to wake up. Keep the server awake or move to an always-on plan.
• It answers with an error. Your endpoint should reply with a success status within a few seconds, even for a user or transaction it has already handled.
• The address is wrong. Check the URL on your placement settings.

We retry a failed notification several times, so a short outage loses nothing. Use Send a test on the Integration page to check the fix straight away.
