currency convertor api

Hello All,

I am new to this forum and SUITECRM so please bare with me.

I have few questions:

  1. Which tool would be better for crm coding. we have configured it on premise and now we want to add some customization to it. Database is also configured.
  2. I have checked few URLs for currency convertor API but now sure whether they give updated value everyday. could you suggest few?
