Update Tag - Markifact

Replaces a tag in a Google Tag Manager workspace with a full Tag resource payload. Workflow: gtm_get_tag, edit the payload, gtm_update_tag, then version and publish.


App	Google Tag Manager
Operation ID	`gtm_update_tag`
Type	Action
Connection	`gtm` (required)
Credits per run	1
Agent / MCP tool	Yes
Requires approval	Yes (write operation)

Inputs

Field	Type	Required	Default	Description
`account`	DynamicAccount	Yes	-	Select the Google Tag Manager account.
`container`	DynamicAccount	Yes	-	Select the container.
`workspace`	DynamicAccount	Yes	-	Select the workspace.
`tag`	DynamicAccount	Yes	-	Select the tag to update, or provide its tag ID.
`tag_payload`	object or string	Yes	-	Full replacement Tag resource (object or JSON string) matching the Google Tag Manager API v2 Tag spec; the update replaces the tag entirely, so include every field the tag should keep. Workflow: gtm_get_tag -> edit the payload -> gtm_update_tag. Read-only fields are stripped automatically. Server containers use different type codes than web containers: the server GA4 tag is ‘sgtmgaaw’, not ‘gaawc’ or ‘gaawe’. An unknown code is rejected by Google as an unknown entity type, so read the exact code from gtm_list_tags on that container instead of guessing, or add the tag once in the Tag Manager interface and copy it back.

Output

Type: Dict Returns the updated tag as provided by the Tag Manager API.
