Does GivePanel show zero dollar (no donation) fundraisers?
No and here's why...
Facebook reporting is still based on transactions (not fundraisers). Therefore if a fundraiser does not have any transactions it does not exist in Facebook reporting.
GivePanel is based on Facebook reporting (even as we integrate with their reporting API). So unless Facebook change the fact they way they report, we will never see zero donation fundraisers in GivePanel. We do not think Facebook will change this.
Please also bear in mind that a VERY high % of zero donation fundraisers soon get their first donation and can then be seen in GivePanel where they can be messaged, labelled and coded.
