Hello,
I review the attachment and I am able fix all the errors. As I have very good experience in Mailchimp integrate. I have worked with more than 30 famous APIs such as Bitrix24 , Mailchimp, Ship station , Instagram , Amazon, Ebay, Google, Zapier, Facebook, zendesk, Linkden, Twilio, DocSign Zapier, Asana etc.
You can also skype for better communication too.
We will discuss all things and then proceed on the project.
I will provide you quality work and reliability
