When using the GET Fetch All Properties endpoint we can specify the x-ads-derivative-format and set it to 'fallback' to retrieve SVF1-compatible objectids. Is this option supported for the POST Fetch Specific Properties endpoint?
POST properties does’t support SVF1 compatible IDs currently, one workaround is to call GET properties endpoint to generate SVF1 compatible IDs, and then use POST properties to query data you want.
