Shopify access for marketing agency

[Setinit]

I recently hired a marketing agency to manage my Google and Facebook ads. They request all-time access to Custom scripts, liquid files, and Shopify reports. 

Do they need this access to run ad campaigns?

Yes, they need to add some keywords and meta tags for the marketing. So don't worry you can give the access.

Thank you

They are not doing any custom development work. Why will they need access to the theme files?
