Adoption of GraphQL in Meta Ads Manager - Bryan Yang & Yuanchao Zhu, Meta Within Meta, there are products still adopting GraphQL. Ads Manager is a large product that is iteratively transitioning to GraphQL from a REST-based API, GraphAPI. This talk will cover why we chose to migrate, challenges we faced and strategies to adopt GraphQL iteratively, without a full product rewrite.
