Existing Messages may be associated with a Publication via the Messages sub-page or the Publication Messages page.
A list of available Publications can be found by appending /ministryplatformapi/publications.svc to your church's base URL (for example, https://sample.church.com/ministryplatformapi/publications.svc). To populate a feed, further append the URL with the desired Publication Name as defined on the Publication record.
Once appended (for example, https://sample.church.com/ministryplatformapi/publications.svc/samplefeed), the content of all associated Messages will appear correctly formatted in an XML file. Do not include a trailing slash after the Publication Name.
See attached PHP and XSLT code to render your MP Publications on a server that renders PHP and has access to libXSLT library (which most PHP hosts have).
Add these two files to your server as is, but replace https://sample.church.com/ministryplatformapi/publications.svc/samplefeed
with your feed url.
