I know it’s a year later, but I had trouble finding this out via the documentation a well, so figured I’d update this here question.
You can use the ` PUT /contacts/ID/edit ` which takes a map of fields to values. You can add “tags” as a field with the value being a comma separated list of the Tags as you want them to be (i.e. Make sure you add the current tags to your value before submitting, or they’ll be blown out). This is actually true for the endpoint as a whole, in my experience. You have to send ALL fields with their current or updated value or they’ll be blown out.
Something like:
```auto
{
"first_name":"John",
"last_name":"Smith",
...
"tags":"Tag1,Tag2,Tag3"
}
```

I think you can set a special parameter so it doesn’t overwrite if it already exists: [Mautic Developer Documentation](https://developer.mautic.org/#edit-contact) the `overwriteWithBlank` param determines that i think
