Kolmisoft MOR API Integration
Hi Digvijay,
As I told you, you did not convinced me to do the job. I know it was not an easy project for you and for many that wants to do API integration with MOR. You need to work on communication with your customer. Maybe another AAPI integration could run better then this MOR API project. Hope the best for you with your work and your career and hope you understand my point. I did not want to leave any comments above. Where it was mandatory by Upwork I needed to write of choose something. For your effort I did left $50. Hope we can close this gracefully.
Regards and success.
