Microsoft Ads how to update campaign status to Paused

Question

On Microsoft Ads, I want to pause a campaign through Api. Here is my flow:

1. CampaignManagementExampleHelper.GetCampaignsByIdsAsync(accountId, campaignIds, campaignType, returnAdditionalFields: null);
2. Set campaign.Status = CampaignStatus.Paused;
3. CampaignManagementExampleHelper.UpdateCampaignsAsync(accountId, campaigns);

I got this:

• Error code: 1155
• Error Message: The campaign type field of a campaign cannot be updated.

I didn't change campaign type at all, so not sure what is the cause.

Any suggestions?

Answer 2

Found a work around (step 3):

1. CampaignManagementExampleHelper.GetCampaignsByIdsAsync
2. Set campaign.Status = CampaignStatus.Paused;
3. set campaign.CampaignType = null;
4. CampaignManagementExampleHelper.UpdateCampaignsAsync

Still feels like a bug, but maybe by design.
