But the audience was unsympathetic when she called her father a "tremendous champion of supporting families and enabling them to thrive", with the moderator moving the discussion on amid a chorus of boos.
Trump, who was recently installed as an unpaid White House adviser, was asked to describe her role. Forced by direct questioning, she shed her "I'm going to be a daughter" persona and instead spoke on behalf of her father's administration.
The remarks come after her brother Eric Trump told The Daily Telegraph that Ivanka has "influence" over their father, and after the reports of the Syrian chemical attack Eric Trump was "sure she said: 'Listen, this is frightful stuff.' My father will act in times like that".
"I think even this discussion on feminism and why it's become so loaded is that I think there can be a negativity attached to labeling because it does feel exclusionary of others", she said.
"You're the first daughter of the United States and you're also an assistant to the president", said panel moderator Miriam Meckel, the editor in chief of the German publication WirtschaftsWoche, in her opening question to Trump.
Ivanka Trump replied: "Certainly not the latter, and I am rather unfamiliar with this role as well, as it is quite new to me".
But when she answered some critical questions both regarding her role in the White House as well as her father's past behaviors, her responses were met with jeers rather than cheers.
"I need to address one more point".
"I've certainly heard the criticism from the media that's been perpetuated", Trump responded, prompting laughter from the crowd.
The scattered groans and hisses came as she described her father as "a tremendous champion of supporting families". Who are you representing: "your father as the president of the United States, the American people or your business?"
Ivanka attempted to brush off criticism of Trump by blaming his negative image on the media, and relying on her own testimony as a daughter who "grew up in a house where there was no barriers to what I could accomplish".
At the W20 Summit in Berlin, which focused on the economic empowerment of women, Trump was part of a panel of leaders that included German chancellor Angela Merkel, who had invited her to participate in what was Trump's first worldwide visit as an advisor to her father.
The summit was a women-focused effort within the Group of 20 countries titled "Inspiring women: Scaling up women's entrepreneurship".
President Trump's "America first" stance, including his questioning of multilateral trade deals, has left many wondering how the US will proceed internationally. "There are many different viewpoints and people hold different opinions and perspectives", she said.
"This is very early for me; I'm listening, I'm learning, I'm defining the ways in which I think that I'll be able to have an impact", Trump said.
President Trump tweeted Tuesday that he is "proud of @IvankaTrump for her leadership on these important issues".
"I'm used to it", Trump said, smiling.
She continued: ‶As a daughter, I can speak on a very personal level.
Trump will also visit a technology college run by the Siemens company and go to the German capital's memorial to the 6 million Jews murdered by the Nazis.
