Major challenge we ran into was intergating GitHub APIs and using it to full potential. Like for verifying whether the submitted information is correct or not and verifying if PR is merged or not. Integrating them means making sure they work smoothly together. This was tough because it required a lot of technical know-how and careful planning to get everything working just right. We had to make sure that our system could properly communicate with other platforms and services through these APIs. Despite the difficulty, we worked hard to overcome this challenge, and it was a big step forward in making our system work smoothly and efficiently for everyone involved.
