Hi @H_ng_Nguy_n_Duy,
In this screenshot you’re using the Data Tag to send the event to the sGTM container, and the name of the event is “Haha”.
Now, in the sGTM container and based on your screenshot, you’re triggering the FB tag in the “Purchase” event. But the event you’re sending to the sGTM container is “Haha”. Therefore, you must create a new trigger using the “Haha” event name and attach it to the tag.
Additionally, ensure that you allow the custom event in Meta Events Manager.
