Attn: Probable regression in Sync Program Member Data REST API endpoint (/members.json)

As moderator, you don’t typically start Nation threads, just finish them. 😉

But... just opened P1 cases for 2 of our clients and am quite sure there’s a widespread REST API problem that started in the last 48 hours. So figured it’s worth sounding the alarm here.

In brief, it’s with the /members.json POST endpoint (a.k.a. Sync Program Member Data). All posts that include PMCF values are returning System Error 611.  A request that only includes the "leadid" value is OK, but also useless.

If you believe you may be affected by the problem, feel free to DM me to review your findings. (But do be sure you know how to test this endpoint.)
