I am using the the Facebook Marketing API to upload offline conversions.
The attached code was working until about 2 weeks ago and now reports the following error.
{"error":{"message":"(#100) The parameter data is required","type":"OAuthException","code":100,"fbtrace_id":"HkpzkWB1I5g"}}
I don't understand why it should simply stop working after working as expected for so long. I don't know how to fix it. Any ideas?
