I checked and the trigger works for me.
curl --location 'https://chatbot.smart.botatende.com/api/integrations/trigger-event' \
--header 'Accept: application/json' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer the_token_from_the_integration_must_be_pasted_here' \
--data '{
"phone": "+5511970712782",
"trigger": "teste"
}'
the_token_from_the_integration_must_be_pasted_here - must be replaced with a token for external API calls from the integration(for privacy reasons we are not publishing it here)
