Upload Microsoft Offline Conversions

UPLOADS OFFLINE CONVERSIONS to Microsoft Advertising (Bing), closing the loop between a CRM and Bing ads so bidding optimises toward real revenue instead of form fills. (Google closed the equivalent endpoint to new integrations; Microsoft's is open, so this path works today.) conversion_name = the name of an OFFLINE conversion goal in the account (list_microsoft_conversion_goals; create_microsoft_conversion_goal creates one). conversions accepts a JSON array OR one row per line as 'key=value;key=value' (msclkid=...;datetime=2026-08-01T14:30:00Z;value=2500). Fields: msclkid (REQUIRED; the Microsoft Click Id captured on the site/CRM), datetime (REQUIRED, UTC ISO 8601), value (optional). confirm=false previews; confirm=true uploads.
