Dec, 2019 - Jan, 20222 yr 1 month

    DESCRIPTION: Leadsquared, a powerful sales and marketing automation platform, plays a pivotal role in generating high-quality leads for BDA (Business Development Activities).

    LIMITATION: The API allows the creation/update of up to 25 user profile records per call, with a maximum of 3 concurrent API calls. Additionally, the system supports a rate of 10 API calls per second for efficient data management.

    • We encountered several errors, such as reaching the maximum limit and profile merge issues, prompting the need to

    implement a 5-second delay before sending the next message to address the issues effectively.

    • We experienced errors during the creation of new leads and activities

    AFTER IMPROVEMENT:

    • Our system operates without encountering daily errors and efficiently processes approximately 1500 messages per minute.

    • After full development, this system was able to handle 30 lac messages per day.
