Merge Contacts endpoint - no response body, merge unsuccessful



Hey all,

API doc says that the "Merge Contacts" endpoint should return a 200 with a response body of "SUCCESS".

Instead, I'm seeing a 200 with an empty response body. The contact I'm attempting to merge is unmerged.

Is this a bug in the API, the docs, both, or user error (aka, me)? Looking forward to any clarifications! I've triplechecked the VIDs are correct - but I could be wrong. The VID is in the URL as circled, I believe:


Hi @LocalMan,

Can you send me your Hub ID, and the vids of the two records you're trying to merge? I can take a look to see if anything is amiss.
