transactionId parameter to create calendar event endpoint does not seem to work in National Cloud environment

Question

When using the https://graph.microsoft.us/v1.0/me/calendars/{calendar_id}/events endpoint to create a calendar event in a GCC High National Cloud tenant, if the transactionId parameter is included, it causes a 400 response with UnableToDeserializePostBody as the error code.

Is this parameter not supported in graph deployed against National Cloud environments? Is there a plan to support it in the future?

Answer 1

check whether extension is added when creating an event

 const eventData = {
      subject: subject,
      body: {
        contentType: "HTML",
        content: description, // You can customize this as needed
      },
      start: {
        dateTime: startDateTime,
        timeZone: startTimezone, // Adjust the timezone as needed
      },
      end: {
        dateTime: endDateTime,
        timeZone: endTimezone, // Adjust the timezone as needed
      },
      extensions: [
        // Include the transaction ID as an extension
        {
          "@odata.type": "Microsoft.Graph.OpenTypeExtension",
          extensionName: "transactionId",
          transactionId: `sch${transactionId}`,
        },
      ],
    };

Hi @Elyes Graba

Since this issue seems to be specific to the National Cloud Graph endpoint, I would recommend you to raise a support case with Microsoft Graph, a Support Engineer will be able to assist you better. You can raise support ticket from:

Hope this helps.
