Sending data from the Google Tag Manager web container to the server c

Hey - I recently set up server side using Stape and GTM. Then, followed this blog to set up the basic, Sending data from the Google Tag Manager web container to the server container.

I created two Data Tags, one for purchase and the other for common data, is that enough for a basic set up?

Not sure however if its all set up correctly? Tested the set up but I seem to missing something.

Can you help please?

Server side GTM container ID - GTM-593RDQNT
Domain name - https://gtm.womankind.org.uk
Host - gtm.womankind.org.uk

There is no right or wrong approach in general. It all depends on what kind of data and events you need in the platform you want to transfer data to.
It is not possible to see what you have configured just by having a container ID and a link to the sGTM subdomain. You need full access to the containers and an understanding of what you want to configure.
If you are not sure about this - I can recommend you to contact some tracking specialist, for example on Upwork or any similar platform.
