So I was talking to the support engineer at PayTM regarding their integration in my app. Idiots!

Many users in my app want PayTM as the payment option. I am using their API and after trying for a few hours, when it was just not working even though I followed their guide and docs, I decide to call the support. After I described him the errors I was getting, he asked me to follow the docs which, being a developer myself, I already did. When I told him that I have done everything exactly as mentioned in the docs, he asked me to hold the phone. Came back after 1 minute and said, "Sir, I discussed the issue with my TL and he says that our API does not work in PostMan."

I hung up.

I managed to make it work by trying evening I could possibly do. But I am amazed what kind of people are running such a giant company. PostMan is made to test APIs. Idiots!
