Hello all, There is a problem to solve.

Hi folks, am developing a Crm application for real estate agent - here the problem is how to connect with real estate marketplaces to generate lead management. How to connect them, where? Or can I connect with third party providers for Api integration ore els Need to approach each marketplace individual.

1. Which option is better?
2. How to approach to ask for connecting Api integration for lead management?
