API Key for Shopify

[angbarllc]

I need someone from Shopify to provide me with my API Key code for my Shopify store, to merge information with another program.  I have not been able to get simple instructions on where to find that code (it is just one code, for the entire store site), nor have I been able to find a way to contact Shopify via direct email, text, or phone messages.  

If anyone has any help out there on how to get in touch with Shopify, please help.

Thank you,

Angel
