The PM API is the list of events that PatronManager publishes, that Groundplan uses to pull events into Wordpress. Find your API in Groundplan >> Settings >> PatronManager API data source URL.
- Open up the API and do a Ctrl + F search for the event name or the event ID (the string of letters and numbers at the end of the event URL, after "id=").
- It will look like a bunch of code, but you should be able to tell if the event name and event id are showing up.
- If the event appears in the API, everything is good on the PatronManager end and something's going on with Wordpress.
- If the event doesn't appear in the API, something is not right in PatronManager. Check your settings there to make sure the event is being published.
