I configured the purchase tag in google tag manager

I also configured the remarketing tags:

add_to_cart purchase view_item view_item_list

I want to use max performance

Should I use the conversion label of my purchase conversion action present in Google Ads for all my Google Tag Manager remarketing tags?

Should I create a conversion action in Google Ads for each remarketing tag and add a different conversion label for each remarketing tag in Google Tag Manager?

Or should I leave the field empty for each conversion label of each of my remarketing tags in google tag manager?

Please enlighten me

THANKS

I don't know how to fill out my conversion labels of my remarketing tags in my google tag manager to advertise google ads

As a frontend developer I've been tasked with the following. The customer is using Google Ads to get traffic to their website A. They can successfully track campaigns in their Google Ads dashboard. Now they want to be able to do the same for website B, which is on the same domain. And they ask me to do it.

Do I need to do anything as frontend developer to make customer able to track UTM campaigns on website B? E.g. do I need to send Google Analytics events, do need to configure something on frontend side?

I found it very hard to find any info on how it actually works (there is a ton of very basic articles on what UTM parameters are, how to generate them and rubbish like that, but nothing about how Google knows when someone landed on a URL with UTM parameters). If anything, I am under impression that it should just work out of the box.

Recently I was exploring Graph APIs(https://developers.facebook.com/docs/graph-api/overview) offered by Meta, while checking through couple of APIs like /message-id and /conversation-id for whatsapp message which I sent to one of my contact number (this contact number I am using as customer number) this APIs are working, instead they are showing error message as follows 'Unsupported get request. Object with ID '{message-id goes here}' does not exist'.

Likewise I am getting same error while trying to fetch details about {conversation-id} which I fetched from webhook, which I integrated to receive notifications about message which I will receive from customer.

Also, a point to note is that.. while reading through Graph API documentation for /messages as well as /conversation APIs is says 'An individual message in a Messenger or Instagram Messaging conversation.' and 'A Messenger conversation between a person and a Facebook Page or an Instagram Professional Account.' does this means this Graph APIs is only accessing for data which is shared over facebook page/messages and/or instagram messages.

What I am trying to acheive using Graph API is to get conversation details for whatsapp business API happened between customer and business.

Please help clear my above concerns.

Thanks, Abhishek
