We want to use Microsoft Ads Conversions API (CAPI) for server-side tracking. Currently, we are not seeing the "Send events from your server" or "Conversions API" option in our UET tag settings. Please enable CAPI access for our account.

    CAPI cannot be enabled directly from the UET tag settings by end users. Access to the Conversions API is currently in a pilot program and must be provisioned for the account by Microsoft.

    To proceed:

    1. Contact the Microsoft Advertising account manager or Microsoft Advertising support and request enrollment in the Conversions API pilot for the specific customer account (CID).
    2. After enrollment, obtain the Conversions API auth token from the Microsoft Advertising UI by selecting Use Conversions API for the UET tag.
    3. Use the provided UET tagID and the auth token to send events to the CAPI endpoint: 
         https://capi.uet.microsoft.com/v1/{tagID}/events
      with the header: 
         Authorization: Bearer <ApiToken>

    Until the account is added to the pilot and the token is issued, the “Send events from your server” / “Conversions API” option will not appear in the UET tag settings.
