The key idea of the integration is that Didomi pushes user actions and consent information into Tealium by firing events/direct calls () to indicate when tags that require consent can be loaded. You should then configure load rules in Tealium to only fire tags after consent has been collected for each vendor.
On your side, the integration relies on adding rules, events and conditions to all the tags from vendors that do not support the IAB framework to make them fire on a custom event from the data layer. The Didomi SDK will then fire an event with the list of vendors that the user has given consent to, which will ensure that Tealium only loads the tags matching the user consent.
For instance, after a user gives consent to the vendor google, the SDK will push the direct call didomi-consent-changed and the variable didomiVendorsEnabled with the value google,. The tags setup in Tealium can then be fired through a load rule on the event didomi-consent-changed.
Make sure that our SDK is setup
Before continuing, please read our section on to learn how to do the initial setup of your tag. It is particularly important that our tag gets embedded before all the other tags on your page.
If you are configuring Didomi through the Console, enable the Tealium integration in you Consent notice -> Cutomization -> Integrations:
Embedding the Didomi SDK through Tealium
We recommend not embedding the Didomi SDK through Tealium. By being directly on your pages, the Didomi SDK can load faster and also ensures that IAB vendors can detect a CMP on the page as soon as possible.
Embedding the Didomi SDK through Tealium will result in less consents being passed to vendors and a lower consent rate from their perspective.
Didomi pushes the user consent status through Tealium events and you will use the tealium_event variable to condition your tags.
Enable the Events extension in Tealium to ensure that the tealium_event variable is available in the data layer and can be used in load rules:
For every vendor tag that you need to condition on the user consent status, create or update a load rule that loads the tag when consent is collected and consent has been given for the vendor.
For instance, to load a Google vendor tag, create a rule with the following conditions:
tealium_event equals didomi-ready
AND didomiVendorsEnabled contains google,
When matching vendors by IDs in variables, use the full ID of the vendor with an additional comma (,) at the end to ensure IDs do not get mixed and matched.
Example: Use google, to match the vendor with ID google and not the vendor with ID googleana-4TXnJigR.
With this load rule configured, your tag will be fired when the page loads AND consent has been given on a previous page for the vendor Google. If you also want the tag to fire when consent is given on the current page, also add a rule when tealium_events equals didomi-consent-changed.

How to find your vendor ID?
If you have your own custom events that you use as rules for tags and also want to add an additional condition on the consent status of the user, you need to make sure that your custom events only fire after the Didomi event that you are using (so that the Didomi variables have already been populated). You have two options to do so.
You need to create load rules that will be used to decide when to load each tag in Tealium. Vendors that do not require consent do not need to be updated. do not need to be conditioned either as they will automatically collect the consent status from Didomi through the IAB TCF API.
See for more information on the values of tealium_event.
See for more information on didomiVendorsEnabled and other variables available to condition your tags.
To find your vendor ID, go to the Vendors and Purposes section of your Didomi account and copy the API ID. Learn more about variables in
Check for more details on custom events.
