API Integration

I am looking for a Freelancer to help me with an API integration project. Specifically, I need help with data integration. The integration will involve a third-party API, however I do not have access to all the necessary API keys. I need assistance in obtaining these keys and integrating the data into my system. Any experience in this area would be helpful. This project is extremely time-sensitive, so speed and efficiency are absolutely essential.
Iam creating same platform as quest.wall.app so need someone expert to handle the task.
