Link Google Merchant Center to Google Ads

[Romain]

Hi,

Our app create merchant center sub accounts for our customers and we need to link them to their Google Ads account.

We previously use the ContentApi to send the invitation, and we accept it with the Google Ads api. Everything was working fine for us.

But the ContentApi will be removed next summer, so I started the migration to use the new Merchant API, and it is not possible anymore to send an invitation link from a Merchant Center to a Ads account via this API.

What is the new method to do that ? I tried with CreateProductLinkInvitation of the GoogleAds API but I got this error :

Field 'product_link_invitation.merchant_center' cannot be modified by 'CreateProductLinkInvitation' operation

With this payload
{"productLinkInvitation":{"merchantCenter":{"merchantCenterId":"xxxXXXxxx"}}}

Any ideas ?

Thanks for your help
